Re: RES: RES: OutofMemoryError running Ejbdoclet

Frank/Raphael,

    I did some hacking with my Ant build scripts and discovered it 
wasn't XDoclet causing the problem.  It looks like the problem had to do 
with the fact that I was continuously calling my <init> target that 
provided the taskdef definitions.  Once I ensured that the <init> target 
was only called once, the build scripts completed with no errors and I 
actually cut the build time in half.  Sorry about the confusion and the 
incorrect assumption.

    Thanks for all of your help.


Regards,

Jeff
