I am trying to create a simple caching XMBean using JBoss 3.2.1 and everything is working fine until I try to use the proxy for the MBean I get the following exception on the client:

The code fragment that is failing is as follows:
try {
SimpleCache xmbean = (SimpleCache) ctx.lookup("jrmp/SimpleCache");
xmbean.create("test");
assertTrue("Able to call MBean without security", false);
} catch (NamingException e) {
} catch (CacheException e) {
}
The proxy fails when calling the xmbean.create("test") method.

The com.sempra.cache.jmx.JmxSimpleCache simple contains an instance of
com.sempra.cache.DefaultSimpleCache that implements com.sempra.cache.SimpleCache. All
work is delegated to this object. Attached is the JmxSimpleCache, DefaultSimpleCache,
and SimpleCache classes/interfaces. Any constructive advice would be helpful. I have
searched the forums, but all the searches are returning hundreds of postings. All of
the ones I have looked at are unrelated
