Hi, Our current project is based on J2EE1.4. We use EJB 2.1 in our services tier and hibernate in the persistence tier. We use Java 5 SDK. Should we migrate to JavaEE5? Does it give me any benefits apart from ease of development? We have addressed most of the development chores by having a framework around the J2EE APIs and using EJB doclets to simplify the creation of deployment descriptors. Migrating to Java EE makes sense only if it provides performance benefits. Are there any performance benefits provided by Java EE 5 apart from that provided by Java 5? Thanks in advance. regards, Anand
