Subject Re: java.lang.LinkageError: Class org/apache/xbean/finder/ClassFinder violates loader constraints
Date Fri, 05 Dec 2008 11:27:40 GMT
Another thing I am noticing is that
module.getClassFinder().getClass().getClassLoader() returns
"configs/j2ee-deployer/2.1.3/car" classLoader, whereas
ClassFinder.class.getClassLoader() return "configs/openejb/2.1.3/car"
classLoader.
