I have checked the net and 99% of the time it is a classpath problem- but I still cannot fix it!
I am getting this with a run a preconfigured build.cmd file.
'package javax.ejb does not exist'
classpath = D:\jbuilder5\jdk1.3\javax.jar;D:\Program Files\Blazix;.
javax.jar contains javax\ejb, which contains the classes.
