Michael, We just cut OpenEJB 0.8.2 a few minutes ago. We are excited about this release as it contains some classpath enhancements, new documentation, and several fixes from Apple.
Download that here: https://sourceforge.net/project/showfiles.php?group_id=44351&release_id= 108833 Some details on the classpath changes are here: https://sourceforge.net/tracker/index.php?func=detail&aid=603784&group_i d=44351&atid=460291 Drop the new OpenEJB libraries in place of the old ones and see if the problem doesn't magically go away. Let us know how it goes.
