Could you post the details of the error from the Eclipse Error log (Window > show view > other > General > Error log)? Thanks!

Switch you web facet version from 3.0 to 2.5. To do this with the new Liferay project wizard click on the "Advanced project confiiguration..." and under the "dynamic web module" switch from 3.0 to 2.5 and try again.

I had the same problem with Eclipse Indigo:

Such an error is usually related to a missing plugin. Not sure which one(didn't care to do detailed research), so I installed a few that might be related and then it worked. I guess it was either "Eclipse Java EE Developer Tools" or maybe "Eclipse Java Web Developer Tools". But since I have installed a couple of others too, I can't say for sure. (Help -> Install New Software).

Thanks Christoph , I was having this error and after installing "Eclipse Java EE Developer Tools" and "Eclipse Java Web Developer Tools" it was fixed
I'm using liferay 6.1 GA and I could create el portlet plugin with dynamic web module 3.0

I ran into a similar problem, where a hook I wanted to import wasn't installing Dynamic Web Module correctly.

This link can help in solving the issue : http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.jst.j2ee.doc.user%2Ftopics%2Ftchangefacet.html. It led me to a solution.

Right click on the project -> Properties -> Project Facets. There you can select the Dynamic Web Module version.

If you have issues applying the Dynamic Web Module in the project, you might need to exclude docroot from the build path. Right click on docroot folder of project -> Build path... -> Exclude. Then you will be able to apply the Dynamic Web Module version that you want by getting into the Properties as I just mentioned.

Regards.
