I have worked this out and can access the RMIAdaptor from a non-master node. Here is
the jboss-service.xml of the jmx-invoker-adaptor-server.sar which was copied from
deploy to deploy-hasingleton:

Notice that the original NamingAlias entry was removed, and both the JndiName and name
of the JRMPProxyFactory were modified.
Now the trouble is not that I can't find the RMIAdaptor, but once I do it complains of
the wrong number of arguments when I use the RMIAdaptor.invoke() method, even though I
am using the correct number of arguments as specified on p. 92 of the JBoss 3.2.3
Admin/Dev Guide. Here is the offending code:
| // add this user's info to the singleton MBean
| rmiAdaptor.invoke(new
ObjectName("grover.mbean:service=AllUserInfo"),
| "addUserInfo",
| new Object[]{userInfo},
| new String[]{"com.hsp.grover.util.UserInfo"});
|
The error messages I get from JBoss:

It is quite strange because I have used the RMIAdaptor.invoke() method a few lines
earlier in this doGet() with no errors using the same number and type of arguments.
Does anyone have any ideas as to why this is happening ?
