Apache Tomcat also works very nicely and there are lots of support. It is also very lightweight for full JEE apps.

Yes, Tomcat also has a very easy to use web interface and is nice and lightweight. The last I can remember is that Tomcat isnt a full scale EE
server in that it doesnt support EJB and MQ.

However for 2cute2shy's purposes Tomcat would also be a good choice.
