Liferay

Sorry for being so late in posting this, but I haven't been doing much looking at the forums lately. I've been working with liferay and maven2 in the last few months. It's easy to use maven2 to build a portlet since you only need to include the portlet related jars in your pom.xml and then the liferay related xml's in your webapp/WEB-INF directory... basically you are just using the maven2 webapp artifact and adding the portlet libraries... the following is an example of what we add when building one. Using maven, I can stand up a new portlet and have it ready to deploy within a minute or two. The only thing to watch out for, is that everytime liferay releases a new version, you have to manually figure out what they changed and update all the dependencies yourself. I lose probably all the time I save, trying to deal with the version upgrades since libraries are always changing. Currently 4.3.1 is giving me a fun headache. Here are the 2 relevant sections that I think will help you, everything else is just a normal portlet webapp (with the liferay xmls included):
