Problems to adding Jboss Monitor

Hi Everybody

I�m have a very serious problem about adding a Jboss Monitor. Both pc�s (jboss server and Application Manager) are Linux and my Jboss is 4.0.4.

I�m already tryed everything and i can�t succesfull.

The following is the list of configurations are made:

- changes in /etc/hosts file. There are communication between the pc �s . The ping command really works (both IP and host name)

-changes in <jboss-server>/http-invoker.sar/META-INF/jboss-service.xml like the following:

<attribute name="InvokerURLPrefix">http://</attribute>;
<attribute name="InvokerURLSuffix">:8080/invoker/EJBInvokerServlet</attribute>
<attribute name="UseHostName">true</attribute>
replace them with the following line,
<attribute name="InvokerURL">http://10.1.9.50:8080/invoker/EJBInvokerServlet</attribute>;

<attribute name="InvokerURLPrefix">http://</attribute>;
<attribute name="InvokerURLSuffix">:8080/invoker/JMXInvokerServlet</attribute>
<attribute name="UseHostName">true</attribute>
replace them with the following line,
<attribute name="InvokerURL">http://10.1.9.50:8080/invoker/JMXInvokerServlet</attribute>;

<attribute name="InvokerURLPrefix">http://</attribute>;
<attribute name="InvokerURLSuffix">:8080/invoker/readonly/JMXInvokerServlet</attribute>
<attribute name="UseHostName">true</attribute>
replace them with the following line,
<attribute name="InvokerURL">http://10.1.9.50:8080/invoker/readonly/JMXInvokerServlet</attribute>;

-changes in <jboss>/bin/run.conf, adding the following lines:

-Djava.rmi.server.hostname=<external hostname>
-Djava.rmi.useLocalHostname=false

Can anybody help me?

Thanks and Regards
