I just began a project, and I have to use Liferay, so I figured the best way to develop new portlets would be the new IDE, but I don't have much time (8 weeks).
It's the first time I have to work with portlets, so it's a little difficult to start without documentation.
Will this documentation be released soon or should I pick another framework to start to work with?

The documentation here would not be comprehensive on portlet development in Liferay but rather just how to use the Liferay Portlet wizard in Liferay IDE. But there is lots of information you need online for Liferay 5.2 documentation that would include portlet development.

I basically did what was described in the video, but when I was trying to add the new portlet to a page in Liferay (as in 2:15 min in the video) the portlet wasn't loaded. It was listed in the selection dialog so it was obviously deployed, but when I added it there was just an animation indicating that it was still loading.
Meanwhile in the console of the Liferay/Tomcat-Server there was an exception being thrown in an infinite loop. The exception starts of with:
"Caused by: javax.portlet.PortletException: javax.servlet.ServletException: javax.portlet.PortletException: javax.servlet.ServletException: javax.portlet.PortletException: javax.servlet.ServletException: Servlet execution threw an exception
at com.liferay.portlet.PortletRequestDispatcherImpl.include(PortletRequestDispatche
rImpl.java:109)"
and is followed by a stack trace of probably hundreds of lines.
What did I do wrong? Why does it work in the video but not on my machine?
These are the software components I am working with:
Eclipse JEE Helios
Liferay Portal Tomcat 6.0.4
Liferay Plugins SDK 6.0.4
Liferay Eclipse Plugin 1.0.1
If you need any more information to understand my problem, feel free to ask!
Any help would be much appreciated!

Same here. I haven't been able to add a simple sample portlet to the portal. The server gets into an infinite loop with exceptions. I'm using the tomcat bundle 6.04 and the plugin sdk 6.04 on Eclipse Helios. Any help will be highly appreciated.

I had the same problem with infinite loop of exceptions. Out of pure desperation I tried to return to the clear starting state, and it worked.
In my case I have delted all the projects from Liferay IDE (including source files), and also all remaining/forgotten portlets from ..liferay-plugins-sdk-6.0.2\portlets\

A work around was posted in the Issue by Gregory Amerson
Here is the quote:
Hey guys, this problem has been fixed in SVN but I haven't gotten the nightly builds fixed as I haven't had a chance to discuss the issue with Brian Chan.
But it is easy to avoid it with the current release of the IDE by simply changing the name of the JSP folder for the mode jsps to be something other than an exact match for the portlet name. See issue IDE-160
-----
Super big thanks to everyone for such a quick reply. I have tested the work around and passed it along to coworkers.
Cheers!

This video is great and helps a lot to create simple portlets.
But, is it possible to have a demo of how to develop portlet with struts actions?
I've tried to modify the portlet.xml to make a StrutsPortlet but the class was missing in my libs... Is there a tutorial somewhere on how to implement solutions with struts actions in a new portlet using liferay ide and liferay-plugins-sdk?

You will likely have to include the struts jars in your portal dependency jars in the liferay-plugin-package.properties. I hope to support more struts development in the future that will make it more straight forward.

Hey guys, if you want to get the fixed portlet wizard that avoids the infinite loop exceptions you can install the nightly build (development stream) here:

I´m a newbie to liferay and pretty frustrated since I´ve been figthing with this infinite loop for couple of days and nothing seems to work out. I tried to rename the folder and installed the nightly build but still no success.

Hi,
Did anyone face problem using service builder in the IDE. First time it works fine. When i tried to add another entity and try to build-service and then deploy it gave me error in the server. So i switched back to using service builder from command prompt.

Hi Bindu
That problem will arise if you use browser version below IE7 & mozilla below 3.5
so use greater versions to work

I successfully created a Portlet per this video. The problem I'm having is modifications to my JSP don't appear when I refresh the web page hosting my portlet.
The only way I can get my JSP changes to show up in the browser is to right click on my project in Eclipse then select Liferay -> SDK -> Deploy. Then when I refresh the page hosting my portlet I can see the changes.
How can I make the modifications to my project files automatically deploy?
