Trying to call a method cluster wide on a service that extends HAServiceMBeanSupport fails with a
message like this:

2009-04-15 18:22:12,325 ERROR [org.jgroups.blocks.MethodCall] (Incoming-19,127.0.0.3:47610) found no method called echo in class org.jboss.ha.framework.server.HAServiceImpl$RpcHandler with (java.lang.Boolean) formal parameters

Looks like the handler linked in HAPartition is not the correct one or not able to cope with remote
method calls.

Example:

public interface EchoMBean extends HAServiceMBean
{
boolean echo(boolean echo);
}

public class Echo extends HAServiceMBeanSupport implements EchoMBean
{
public boolean echo(boolean echo)

{ return echo; }

}

</mbean>
</server>

public void testTrueEcho() throws Exception
{
MBeanServerConnection[] adaptors = this.getAdaptors();
ObjectName on = new ObjectName("cluster.rspfilter:service=Echo");
Object[] args = new Object[] {"echo", new Object[]

{true}

, new Class[] {boolean.class}};
String[] signature = new String[]

{String.class.getName(), Object[].class.getName(), Class[].class.getName()}

;
List resps = (List) adaptors[0].invoke(on, "callMethodOnPartition", args, signature);
log.debug("Response list: " + resps);
assertEquals(1, resps.size());
if (resps.get(0) instanceof Exception)

{ throw (Exception)resps.get(0); }

assertTrue(((Boolean)resps.get(0)).booleanValue());
