Using Yahoo Query Language in Liferay(YQL)

Yahoo Query Language (YQL)

The Yahoo Query Language is an expressive SQL-like language that lets you query, filter, and join data across Web services. With YQL, apps run faster with fewer lines of code and a smaller network footprint.

Download Liferay YQL portlet from following location

You can find source and war file

https://sourceforge.net/projects/meeralferay/files/LiferayYQLPortlet/

Note: Portlet developed in Liferay 6.1GA2 EE version

If you want deploy in CE version you just do changes in liferay-plugin-package.properties

Understanding YQL:

Yql provide syntax’s like sql so that we can fetch data from yahoo web services.

We already know about web service like SOAP and REST but YQL is very simple to use in web sites.

This is very special language to yahoo to fetch yahoo data .

But we can also provide our data available to YQL using data tables.

The following scenarios we can use YQL

Fetch Weather Information
Fetch Stock Market Information Up to date
Currency conversion
Fetch yahoo news

How to use YQL:

Open Yahoo console from fowling URL

http://developer.yahoo.com/yql/console/

Select any tables which are left side

Select any tables it will populate sample query in console text box

You can click on Test button and see the result.

Here YQL provide to kinds of data JSON and XML before click on test button you can select any of formats then data will be showed in result part.

Once the result is desirable then copy the URL which showed in bottom this URL can be used to get content.

Once get content you can display into your website

Example:

Lets us assume we want display weather information in our web site:

Go to Yahoo console

http://developer.yahoo.com/yql/console/

Execute following YQL query

select * from weather.forecast where location=90210

Select JSON and Test

In the result you can see the data related to weather you can identify json or xml structure and retrieve in website.

We can use YQL in different ways:

I suggest you use two ways

YUI YQL java script library

Simple jquery AJAX

YUI YQL java script library:

To use YQL in your application first we need following YQL and YUI library

And use YUI use method and add required modules we need to add yql module when we work with YQL

The following is complete code

YUI().use('node','yql', function(Y) {

var res = Y.one('#res');

var woeid = '2502265';

Y.YQL('select * from weather.forecast where woeid='+woeid, function(r) {

var el = Y.Node.create('<div class="mod"></div>');

el.set('innerHTML', '<h2>Weather for ' + zip + '</h2>' + r.query.results.channel.item.description);

res.set('innerHTML',r.query.results.channel.item.description);

});

</script>

<div id="res">Weather Info Here</div>

Simple jquery AJAX:

We can also used jquey Ajax to execute YQL queries

Generally All YQL queries requested by following URL

http://query.yahooapis.com/v1/public/yql

We need to pass following parameters to above URL

q : the YQL query which you desire

format: type of data xml or json

env: env is type of parameter which specified where data table are available

For more info we need read about data tables

diagnostics: is Boolean value it will give error information in response if anything fails

callback: is optional parameter

The following is example:

http://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid=2502265&format=json&diagnostics=true&env=http://datatables.org/alltables.env&callback=

Note:

When we execute any YQL statement in YQL console for each statement we will gate URL in the bottom

If see URL you can identify url and its query string but here all parameters are encoded format.

For know what parameters using you yql statement you can decode URL. The following is URL decoding in online.

http://www.url-encode-decode.com/

$(document).on('ready',function(){

var weatherQuery='select * from weather.forecast where woeid=2502265’

$.ajax({

url: 'http://query.yahooapis.com/v1/public/yql',

dataType:"json",

data: {

q:weatherQuery,

format:"json",

diagnostics:"true",

env:"http://datatables.org/alltables.env",//env:"store://datatables.org/alltableswithkeys",

callback:""

type: "get",

success: function(r){

$('#res').html(r.query.results.channel.item.description);

beforeSend: function(){

complete: function(){

error: function(){

}

});

</script>

<div id="res">Weather Info Here</div>

YQL can fetch against yahoo web services

The following are some information about data tables

You can see all tables and execute query in YQL console and find the data structure and use

Get Stocks quotes information:

Table: yahoo.finance.quotes

Query: select * from yahoo.finance.quotes where symbol in ("YHOO","AAPL","GOOG","MSFT")

Get Stock Market Indexes

Table: yahoo.finance.quoteslist/ yahoo.finance.quotes

Query: select * from yahoo.finance.quotes where symbol in ("^hsi","^bsesn","^nsei","^dji","^ixic")

Get Top Stories from news table:

Table: yahoo feed

Query: select * from feed where url='http://news.yahoo.com/rss/topstories'

Get Weather Organization ID(Weoid) from Longitude and Latitude

Table: geo.placefinder

Query: select * from geo.placefinder where text="22.2500,114.1667" and gflags="R"

For more info about gflags: http://developer.yahoo.com/boss/geo/docs/control-parameters.html

Get Weather Organization ID(Weoid) from Address

Table: geo.placefinder

Query: select * from geo.placefinder where text='Central,Honk Kong' and gflags='R'

WE can also fetch html from websites using YQL

If some time we did not find any web services simple from web page you can fetch data and you can filter the content.

Here in where condition we need to pass xpath notation

Fetch some use full data from Yahoo finance page like all Stock indexes

select * from html where url="http://finance.yahoo.com/" and xpath='//div[@class="desc"]'

select * from html where url="http://finance.yahoo.com/q?s=yhoo" and

xpath='//div[@id="yfi_headlines"]/div[2]/ul/li/a'

Note:

We can open page and identify the required content from page using Chrome inspect element option.

Find the xpath of content and apply to YQL.

Important Points:

YQL is like sql statements to fetch content from yahoo web services.
These all information they provided as data tables. So that we can use YQL against data tables to fetch the content.
YQL provide xml and JSON formats.
Each YQL statement can be provided as web URL so that we can directly execute in browser and see the result.
To fetch the content from data table yahoo provides one URL and we need to use that public URL and pass some query parameter to get result. By this we can send Ajax calls.
Yahoo provide special module YQL module from their java script library i.e. YUI.
We can use YUI yql library to get content from data tables.
YQL very convenient way to use in web site because we can use this with java script libraries like jquery,YUI or other java script libraries.
YQL also provide way to fetch html content for web page as json or xml format so that we can use this data in website this scenarios happen when we don’t have web services.

Liferay Auto fields

Nagul Meera Mahankali

Liferay Auto fields

The following example gives you the information about how to use liferay auto fields in liferay development.

Life ray auto fields concept provides you can add multiple input fields dynamically to the form.

Means if you want add multiple input fields to the form based on user choice.

Download Auto field portlet from following location

https://sourceforge.net/projects/meeralferay/files/LiferayAutoFieldsPortlet/

Note: Portlet developed in Liferay 6.1GA2 EE version

If you want deploy in CE version you just do changes in liferay-plugin-package.properties

Liferay 6.1 EE version

liferay-versions=6.1.1

Example:

Adding multiple phone numbers

Adding multiple addresses

Add multiple images or document

When we get above requirement we can use auto fields.

Here we have to identify which fields you want make it multiple times such fields you have to wrap into particular div or field set. We have to provide that element id to the auto filed script so that when we click add button that wrapper content will be cloned.

At time of clones all names and ids of fields will become unique.

The following g is example code for auto fields

Add following script in jsp page

<%@page import="javax.portlet.ActionRequest"%>

<%@ include file="init.jsp" %>

<portlet:actionURL var="editArticleActionURL" windowState="<%= WindowState.NORMAL.toString()%>">

<portlet:param name="<%=ActionRequest.ACTION_NAME%>" value="getAutoFieldsData" />

</portlet:actionURL>

<h1>Liferay auto fields example</h1>

<aui:form action="<%=editArticleActionURL%>" method="post" name="LiferayAautoFieldForm">

<aui:input fieldParam='phoneNumber0' id='phoneNumber0' name="phoneNumber0" label="Phone Number" />

<aui:select id="phoneTypeId0" name="phoneTypeId0" label="Type">

<aui:option value="11006" label="Business"></aui:option>

<aui:option value="11007" label="Business Fax"></aui:option>

<aui:option value="11008" label="Mobile Phone"></aui:option>

<aui:option value="11009" label="Other"></aui:option>

<aui:option value="11011" label="Personal"></aui:option>

</aui:select>

</div>

<aui:layout>

<aui:column>

<aui:button type="submit" value="Save Phone Numbers" name="SavePhoneNumbers"

onClick="saveData();"></aui:button>

</aui:column>

</aui:layout>

<aui:script use="liferay-auto-fields">

new Liferay.AutoFields(

{

contentBox: '#phone-fields',

fieldIndexes: '

<portlet:namespace />

phonesIndexes'

}

).render();

</aui:script>

</aui:form>

Add following AUI java script in jsp page.

<aui:script use="liferay-auto-fields">

new Liferay.AutoFields(

{

contentBox: '#phone-fields',

fieldIndexes: '<portlet:namespace />phonesIndexes'

}

).render();

</aui:script>

Add following code in Action class

public void getAutoFieldsData(ActionRequest actionRequest,ActionResponse response)

throws Exception {

System.out.println("=============getAutoFieldsData==");

String phonesIndexesString = actionRequest.getParameter(

"phonesIndexes");

System.out.println("=============phonesIndexesString=="+phonesIndexesString);

int[] phonesIndexes = StringUtil.split(phonesIndexesString, 0);

for (int phonesIndex : phonesIndexes) {

String number = ParamUtil.getString(actionRequest, "phoneNumber" + phonesIndex);

System.out.println("=============phoneNumber=="+number);

int typeId = ParamUtil.getInteger(actionRequest, "phoneTypeId" + phonesIndex);

System.out.println("=============typeId=="+typeId);

}

Liferay LDAP Integration full detailed information

Nagul Meera Mahankali

Liferay LDAP Integration

Liferay 6.1 version:
Please go through following link to get understanding about Ldap liferay integration

http://www.liferaysavvy.com/2013/02/life-ray-ldap-integration.html

Click on Add button you can add your LDAP server configuration. You can also add multiple LDAP servers.

Server Name: anything that your choice.

Server Types: This server you have used like Apache AD, Microsoft AD or OpenLDA.

Base Provider URL: this is LDAP URL to connect your server. General port number for LDAP is 389.

Base DN: This specify that where exactly your user nodes available

Example:

meera.com is my company

I have organization units Finance, IT

In organization I have users

Then Base DN likes: CN=users,OU=finance,DC=meera,DC=com

If I have two users in names are Peter in finance and Tom in IT

Then exact user Node like this

CN=Peter,CN=users,OU=finance,DC=meera,DC=com

CN=Tom ,CN=users,OU=IT,DC=meera,DC=com

The following are the base DN for above server

CN=users,OU=finance,DC=meera,DC=com : find users in meera company finance organization

CN=users,OU=IT,DC=meera,DC=com : find users in meera company IT organization

OU=IT,DC=meera,DC=com : find users and others type objects in meera company in IT organization

OU=finance,DC=meera,DC=com : find users and others type objects in meera company in finance organization

DC=meera,DC=com : find users and other objects /nodes in meera company in both organizations IT and finance

Above all we can specify as base DN based on your requirement

Principle: this is like user name to connect to your LDAP server means admin username

Credentials: this is password means admin password of LDAP

Once you complete all above then click on test server button and see the result you will get following pop up

Now we successfully connected to LDAP server

Configure Authentication Filter and Import Filter

Now go to user section in same screen you can find following screen

You can find first text box is Authentication Search Filter

Note: Here authentication filters and import filter is very important.

Authentication Filter:

This means in which base user will be searched in ldap when user trying login in life ray means when we use liferay authentication by emailAddreess then we need to map liferay email address with appropriate attribute in ldap

(mail=@email_address@)

When its by screen name

Then we need to map liferay screen name with appropriate attribute in LDAP

(cn=@screen_name@)

(sAMAccountName==@screen_name@)

Note here whatever attribute you are going to use then value of attribute should not be duplicate.

Import filter:

This is used to search users from ldap based on filter and all matched results will be imported into

Liferay User_ table

Here we need to consider one thing whatever the import filter used that results should have email address related ldap attribute and screen name mapping ldap attribute otherwise we will get more exceptions.

Here generally we import mostly users means in ldap is objectClass=person.

We can also narrow the filter by using ldap filters more details how to pass ldap filter go through following link

http://docs.oracle.com/cd/E19528-01/819-0997/gdxpo/index.html

Note: Some times in ldap all nodes may not be persons and if persons them may not have email address related attributes or screen name attribute in ldap then we get more import problems

So here we need to give proper import filter so that all nodes have mail related attribute or screen name related attributes

Generally the life ray screen name equal attribute cn or sAMAccountName

Similarly liferay email address equal attribute in ldap is userPrincipalName or mail

These attributes should be present in each object class=person node otherwise import issues we can expect.

Example import filer

(objectClass=person) means it will search all ldap nodes that would be object class is person nothing but user. Some time object class may be organizationUser too.

Another Example Filter:

& is operator like and operator in java similarly | is like || operator in java

(&(objectClass=person)(|(department=finace)(department=it)(department=sales)))

The above meaning is the node is person and he is belongs to any one of the department.

Import mappings

Import mapping used when user is import from ldap to liferay User_ table.

Here we are mapping required attribute for liferay from ldap.

In ldap has many attribute for user or objectClass=person.

So we map each appropriate ldap attribute with liferay attributes

Example

Liferay attribute	LDAP attribute
emailAddress(should not duplicate)	mail / userPrincipalName
Screenname(should not duplicate)	cn/ sAMAccountName / name
password	userPassword
First Name	name/
Last Name	sn
Job Title	title
Group	department

Now we successfully created LDAP server and we also specify the user mappings to import users into liferay

Now we need set some configuration so that when user should be import what are the password policies we need when create password.

The following screen show that configurations

Enabled:

This is starting point to LDAP integration when we enable then only LDAP is integrated to Liferay so we should enable when you want integrate ldap with liferay.

When we enable LDap when the user going to authenticate will search in LDAP tree if user find then it will set ladapAuthentication true and user will be imported.

This for every user when they login first time or first attempt then user will be imported.

Required:

Make exceptions for omni admins so that if they break the LDAP configuration, they can still login to fix the problem

Import Enable:

When we enable this all LDAP user will be imported into liferay User_ table and related entries in other tables like Group_

Import on Startup Enabled:

when we enable this all users will be imported at the time of liferay server starts.

Once user is imported then one entry is created in LOCK_ table. This specifies that for what intervals import should be happened. This property we can set in portal properties

Use LDAP Password Policy:

When enable Use LDAP Password Policy option in configuration then when login it won’t ask change new password. Only ask terms and conditions otherwise it will ask change to new password when user is attempt first login.

Important Observations:

GroupFriendlyException:

Reason when the user import it is based on liferay user attributes mapping to ldap attribute user will be created.

Generally cn or sAMsaccount as screen name.

When user imported cn will become as screen name in User_ table. And one more entry is created in group_ table the friendly url same as screen name means /the secreen name or /cn

When this Friedly URL is duplicate in Group table then you can see GroupFriendlyException when you get these exceptions the user won’t be imported.

So here we need to very much care full screen name should not be duplicate mean in ldap there are thousands of users, we need to identify attribute value in ldap that should not be duplicate.

If the ldap some thing duplicate mean cn or saMsAccount then should not use these attribute as screen name.

One more thing when we enable import enables then all users will automatically import into User_ table based on configuration.

So here thing is when we enable import enable option in configuration means all ldap users will be imported into liferay.

If we not enable import enable then each user their first login will be imported.

Import on start up means when server start then all user will be imported automatically. The entry will be created in LOCK_ table there you can see expiration Date column. One expiration date less than current date then again import will be start until import won’t be activated.

We can choose authentication either by email Address or by screen name

If we choose any one email mapping in ldap attribute and screen name mapping in ldap should not be duplicate if such case we get

UserScreenNameException or UserEmail Address exceptions

When we use authentication by email address as our authentication type its better we can make auto generated screen name then it won’t be any problem when all users is importing. But email should be unique.

When we use screen name it should not be numbers in start of screen name. If such case please set portal property users.screen.name.allow.numeric=true.

You can also change screen name valuator according to your choice by following property.

users.screen.name.validator=com.liferay.portal.security.auth.DefaultScreenNameValidator

Input a class names that implements com.liferay.portal.security.auth.ScreenNameValidator. This class will be called to validate user screen names

users.screen.name.generator=com.liferay.portal.security.auth.DefaultScreenNameGenerator

Input a class names that implements com.liferay.portal.security.auth.ScreenNameGenerator. This class will be called to generate user screen names.

Email address should not be starting with number such case you will get UsereEmaillAddress exception.

You can change userEmaildAddressPolicies you can also skip email address when user in imported by following property.

Related Properties:

users.email.address.required=true

Set this to false if you want to be able to create users without an email address. An email address will be automatically assigned to a user based on the property "users.email.address.auto.suffix".

users.email.address.auto.suffix=@no-emailaddress.com

Set the suffix of the email address that will be automatically generated for a user that does not have an email address. This property is not used unless the property "users.email.address.required" is set to false. The auto generated email address will be the user id plus the specified suffix.

users.email.address.generator=com.liferay.portal.security.auth.DefaultEmailAddressGenerator

Input a class names that implementscom.liferay.portal.security.auth.EmailAddressGenerator. This class will be called to generate an email address for a user that does not specify anemail address. This class will only be used if the propertyusers.email.address.required" is set to false.

users.email.address.validator=com.liferay.portal.security.auth.DefaultEmailAddressValidator

Input a class names that implementscom.liferay.portal.security.auth.EmailAddressValidator. This class will be called to validate user email addresses

users.full.name.generator=com.liferay.portal.security.auth.DefaultFullNameGenerator

Input a class names that implementscom.liferay.portal.security.auth.FullNameGenerator. This class will be called to generate a full name from the user's first, middle and last names

users.full.name.validator=com.liferay.portal.security.auth.DefaultFullNameValidator

Input a class names that implements com.liferay.portal.security.auth.FullNameValidator. This class will be called to validate user first, middle and last names.

Important LDAP Properties In liferay:

ldap.factory.initial=com.sun.jndi.ldap.LdapCtxFactory

Set the values used to connect to a LDAP store means LDAP implementation class

ldap.referral=follow

ldap.page.size=1000

Set the page size for directory servers that support paging. This value needs to be 1000 or less for Microsoft Active Directory Server.

If you want more search results for Microsoft AD server then AD server admin can configure this number in AD configuration. Please contac admin to set this value from AD server configurations.

ldap.range.size=1000

Set the number of values to return in each query to a multivaluedattribute for directory servers that support range retrieval. The range size must be 1000 or less for Windows 2000 and 1500 or less for Windows Server 2003.

ldap.auth.method=bind / dap.auth.method=password-compare

Set either bind or password-compare for the LDAP authentication method. Bind is preferred by most vendors so that you don't have to worry about encryption strategies.

LDAP Password Import Algorithm:

Set the password encryption to use for comparing passwords during import and to use for encrypting passwords during export. Comparing password during import will only be used when the property "ldap.auth.method" is set to password-compare. If the encryption is set to NONE, which is the default value, passwords are considered as plain text. The SHA-51 algorithm is currently unsupported.

#ldap.auth.password.encryption.algorithm=BCRYPT

#ldap.auth.password.encryption.algorithm=MD2

#ldap.auth.password.encryption.algorithm=MD5

ldap.auth.password.encryption.algorithm=NONE

#ldap.auth.password.encryption.algorithm=SHA

#ldap.auth.password.encryption.algorithm=SHA-256

#ldap.auth.password.encryption.algorithm=SHA-384

#ldap.auth.password.encryption.algorithm=SSHA

#ldap.auth.password.encryption.algorithm=UFC-CRYPT

ldap.attrs.transformer.impl=com.liferay.portal.security.ldap.DefaultAttributesTransformer

You can write your own class that implements com.liferay.portal.security.ldap.AttributesTransformer to transform the LDAP attributes before a user or group is imported to the LDAP store.

LDAP Connection Properties:

Specify the settings for LDAP connections. Any property prefixed with "ldap.connection." will be passed to the LDAP context as an environment variable. See the following link:

http://docs.oracle.com/javase/6/docs/technotes/guides/jndi/jndi-ldap.html#POOL

ldap.connection.com.sun.jndi.ldap.connect.pool=true

ldap.connection.com.sun.jndi.ldap.connect.timeout=500

ldap.connection.com.sun.jndi.ldap.read.timeout=15000

ldap.import.interval=10

ldap.import.method=user or ldap.import.method=group

We have choose any one of two

Set either user or group for import method. If set to user, the portal will import all users and the groups associated with those users. If set to group, the portal import all groups and the users associated thosegroups. This value should be set based on how your LDAP server stores group membership information.

ldap.import.lock.expiration.time=86400000

Set the lock expiration time for LDAP import. By default, the expiration time is 1 day.

ldap.import.group.search.filter.enabled=true

If set to true, the group filter will be applied, but only to groups in the specified base DN. If set to false, the filter will not be applied and all groups that are associated with the imported users will be imported regardless of the base DN.

ldap.import.group.cache.enabled=true

Specify whether group DN lookups will be cached during LDAP import and login. If set to true, this will speed up LDAP import and login, but updates to group attributes will not be recognized until the cache entry expires. The cache size and timeout may be configured in the configuration file specified in the property "ehcache.single.vm.config.location".

ldap.import.create.role.per.group=false

Set this to true if the portal should automatically create a role per group imported from LDAP. The role will be assigned to the group so that users can automatically inherit that role when they are assigned to the group.

Set these following values to be a portion of the error message returned by the appropriate directory server to allow the portal to recognize messages from the LDAP server. The default values will work for Fedora DS.

ldap.error.password.age=age

ldap.error.password.expired=expired

ldap.error.password.history=history

ldap.error.password.not.changeable=not allowed to change

ldap.error.password.syntax=syntax

ldap.error.password.trivial=trivial

ldap.error.user.lockout=retry limit

ldap.import.user.password.enabled=true

Set this to false when the LDAP user's password should not be imported.

ldap.import.user.password.autogenerated=false

Set this to true to auto generate the password for imported users from LDAP This property is only in use if the property "ldap.import.user.password.enabled" is set to false.

ldap.import.user.password.default=test

#ldap.import.user.password.default=screenName

Set either screenName or plain text as the default password for the imported LDAP user. Setting the value to screenName will use the user's screen name as the password for the imported LDAP user. Setting the value to any other plain text value will use that value as the password for the imported LDAP user. This property is only in use if the properties "ldap.import.user.password.enabled" and "ldap.import.user.password.autogenerated" are both set to false.

ldap.user.ignore.attributes=

Set the user attributes that are controlled from the portal. When adding or updating a user from LDAP, these attributes will be skipped.

#ldap.user.ignore.attributes=aimSn,comments,facebookId,facebookSn,greeting,icqSn,jabberSn,jobTitle,languageId,msnSn,mySpaceSn,openId,prefixId,reminderQueryAnswer,reminderQueryQuestion,skypeSn,smsSn,suffixId,timeZoneId,twitterSn,ymSn

Note: If you want change any portal properties related to LDAP simple you can create portal-ext.properties file and add properties and change to required value. This file should be in Liferay_Home directory.

Important java classes involved in LDAP liferay integration:

com.liferay.portal.security.auth.LDAPAuth.java
com.liferay.portal.security.ldap.PortalLDAPImporterImpl.java
com.liferay.portal.security.ldap.DefaultLDAPToPortalConverter.java
com.liferay.portlet.login.action.LoginAction.java

Example of LDAP tree

CN=Users ,OU=finance,DC=watsons,DC=local DC=com

CN=Commn Name

OU=Organization Unit

DC=Domain Name

CN=Users,DC=watsons,DC=local
