Try setting the contextclassloader to the classloader of your bundle i.e.,
ClassLoader ccl = Thread.currentThread().getContextClassLoader();
try
{
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
// do context init
}
finally
{
Thread.currentThread().setContextClassLoader(ccl);
}
That should do the trick.
