I have an intermittent problem generating deployed code for EJB's within VAJ. This normally occurs if I have had to delete the bean, move it to another package or if it has become invalidated for some reason or other. Most of the time, the only error message I get is "Could not compile required classes" which is helpful!! It seems that a number of people have experienced this having looked on some Java forums, but no one seems to have an answer!?
