Hi Sacha,
Thanks for replying.
I had posted this to Jboss Forum before hitting this list.
The reason behind posting this query to
Ejb-Interest forum is to know whether there is anything wrong
With my approach in general or any other such general issue.
I am using Jboss-3.0.3 and could not find any backlog in
jboss-service.xml.
Here goes the snippet from Jboss-Service.xml.
<!--
==================================================================== -->
<!-- Invokers to the JMX node
-->
<!--
==================================================================== -->
<!-- RMI/JRMP invoker -->
<mbean code="org.jboss.invocation.jrmp.server.JRMPInvoker"
name="jboss:service=invoker,type=jrmp">
<attribute name="RMIObjectPort">4444</attribute>
<!--
<attribute name="RMIClientSocketFactory">custom</attribute>
<attribute name="RMIServerSocketFactory">custom</attribute>
<attribute name="RMIServerSocketAddr">custom</attribute>
-->
</mbean>
Thanks,
Saroj
