Subject Re: java.lang.LinkageError: Class org/apache/xbean/finder/ClassFinder violates loader constraints
Date Fri, 05 Dec 2008 19:07:15 GMT
The openejb classloader is getting into the way because of the plugin's
dependency on j2ee-corba-yoko/xxx/car.  This is a dependency that is not
required as of now (may be it will be reuquired if ejb binding is used).
Removing this dependency got me past the linkage error.
