I'm considering developing an application as portlets, to be integrated in Liferay portal. Are there any significant disadvantages or restrictions in developing such an application, as opposed to developing a normal web application using Spring framework? Liferay seems to require that all content is added as portlets. Another option I p...
Hi, I'm currently working on a portlet for the Liferay portal server. I'm using the liferay-ui:icon constructs in my JSP code which support already the localization in many different languages.

I have a GWT app that I want to build as a Portlet. I have already done that with Liferay but the portlet generated (.war file) cannot be deployed into Apache Pluto.

Hi, I am implementing jsr 186 portlets, with some servlets to the mix to implement some ajax. The problem is if I only make AJAX calls for some time, I lose the session.

I know this is not specifically a programming question, but programmers will often have to do this work. How do I create a website with Liferay portal - the docs are pretty light on this fundamental issue and are all for version 4.4. I am using version 5.2 and the docs don't seem to be relevant. Do you know what the basic steps are. So...

This has many obvious benefits. However. I ...

I have a Struts portlet being used in a Liferay Portal environment. I have been localizing my resource strings using standard resource files so far.

I'm having a strange problem and no luck debugging. I was tasked with writing a JSR168 compliant portlet to search a database. When you open the portlet, you're given 6 search boxes for different criteria to search several thousand records.
