Not so sure about NetBeans but in MyEclipse Ant is pretty fussy. I can set up <path id= to point to various libs and then a <path refid= to the main class path and openjpac doesn't find the classes. Now I find if I add my classes and libs to the openjpac class path instead of the ant config then it works. Not really sure why but don't really care either :)
I didn't have this issue on OpenJPA 1.2.x Chris -----Original Message----- From: Rick Curtis [mailto:curti...@gmail.com] Sent: Tuesday, 18 May 2010 12:25 AM To: users@openjpa.apache.org Subject: Re: Ant based enhancement I'm not an ant expert, but I do notice that in the blog posting the openjpac task specifies a <classpath> element. Try working that element in to see if it clears up your problems.
