Welcome!

The gwt-chatrooms-portlet is very simple portlet which demonstrates how to write Liferay portlets using GWT. It is not stable, not secure, not even complete, and should NOT be used in production environment.

Its only purpose is to provide demo code for the following blog posts:

• Liferay GWT portlet - how to make it "instanceable" and use GWT RPC
• Liferay GWT portlet - replacing GWT-RPC with JSON
• Liferay - preserve GWT portlet state between reloads
