Access Felix Gogo Shell in Liferay 7.2/DXP Portal Environment

Meera Prince

Apache Felix Gogo shell is command line interface (CLI) to interact with Liferay Module Framework or OSGi container.

It will provide set of predefined commands to access bundle or modules information like list bundles installed in OSGi container, Services Registry Information and Dependency Management related details.

We have many ways to access the Apache Felix Gogo shell

Command Prompt in Windows
Putty Terminal
Liferay Blade CLI
From Liferay Portal Control Panel

Command Prompt in Windows

Make sure portal server should be started before start using Apache Gogo shell.

Open command prompt in windows and use following telenet command.

telnet localhost 11311

Use simple command lb it will list the bundles installed in the OSGi container.

Gogo shell using 11311 is default port number configured by Liferay Portal and we can change the port number as well.

Use disconnect to end the session.

Note:

Should not use shutdown, close, and exit commands in the Gogo shell and it will lead to showdown OSGi framework.

If you see “Telnet is not recognized as an internal or external command” enable Telenet in windows. Follow below link
