Testing EJBs

What's the fuss about testing outside of a container

Some frameworks stress the importance of testing an EJB within its container. Others argue that it's important to test an EJB outside of its container. In today's
Forums, prasadgc writes "Think about this: Is a POJO testable outside its container (i.e., the JVM)? Is a servlet or JSP testable outside the web container? Why is it a requirement for EJBs alone to be testable outside their container? All Java components (POJOs, servlets or EJBs) are managed components to some degree, because they rely on a containing framework to do some (or a lot) of their work for them."

SKaffman writes "One aspect which I'd like to see given more emphasis is that of deployment descriptors, specifically regarding the use of "hide-the-nastiness" tools like xdoclet. Would you expect xdoclet to still have a place in your model, or do you see no need to have it generate the reams of redundant code and complex descriptors which we have now?"

Ron Hitchens continues the Effective Java Programming Language Guide forum with Item 33: Beware the performance of string contatenation. Ron writes that "This has to be one of the most common Java programming mistakes. Do you understand how implicit string concatenation is performed? Do you know when it's safe to concatenate strings with the "+" operator and when you should use a StringBuffer object to build up a string?"

This allows sites to hide their internal structure, gracefully handle moved content and planned outages, etc.
