I have been encountering problems when attempting to re-generate deployed code when splitting EJB's from one group into multiple packages. Does VAJ expect (or require) one package per EJB group?
Prasad Thammineni VAJ does not expect nor require one package per EJB group. For example, the EJB samples - "HelloWorld" and "Increment", that are shipped with VAJ reside in two different packages. They are both in the same EJB group "IBMEJBSamples".
For a list of limitations imposed by VAJ 3.02 refer to "Limitations" section in Chapter 1 of the product documentation titled EJB Development Environment.
