I want to ask a question about the java web application. When I start to learn the JSP, I always hear about the Java EE web application. But I don’t know the actually meaning of that word. Can anyone explain this word to me? Thank you.

There is a hierarchy of Java distributions.
Starting with Java ME — micro edition for embeded applications on small machines like phones.
Moveing on to JavaSE which is the standard edition most programmers are familier with.
Then moving up to J2EE — enterprise Edition. In addition to SE a J2EE distribution must support several Enterprise level libraries and APIs in the javax…. series of interfaces. The most important of these are the “transactional container”, EJB and WS* web services APIs.
These interfaces are implmented by third parties some open source such as GlassFish and JBOSS but mostly by proprietary (end expensive) products like WebLogic or WebSphere.
