Here I want to report my experiences using Java EE 5 and in particular WebLogic Application server:
EJB 3.0 Post Construct talks about my understanding of the specification, that
Non ASCII Char and HTTP Request instead is a different, incompatible, behaviour in managing NON-ASCII char between Tomcat and WebLogic
With WebLogic Split Deployment with Maven you can read an introduction on using this very productive way of working with WebLogic, using Maven and a new plugin
Generics Support and Fast-Swap talks about the fact that using this new WLS feature you must be careful using generics and protected methods.
