Re: java.lang.LinkageError: Class org/apache/xbean/finder/ClassFinder violates loader constraints
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.

Re: java.lang.LinkageError: Class org/apache/xbean/finder/ClassFinder violates loader constraints
I think I ran into this problem while changing trunk to try to use transitive dependencies and introduced the xbean-finder classloader plugin to solve it. I think you'll have to move your development to trunk or backport the fix. Personally I'd use trunk. thanks david jencks On Dec 5, 2008, at 3:27 AM, Vamsavardhana Reddy wrote: 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.

Re: java.lang.LinkageError: Class org/apache/xbean/finder/ClassFinder violates loader constraints
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. ++Vamsi On Fri, Dec 5, 2008 at 11:30 PM, David Jencks [EMAIL PROTECTED]wrote: I think I ran into this problem while changing trunk to try to use transitive dependencies and introduced the xbean-finder classloader plugin to solve it.
