Accessing OpenJMS server from different machines

Hi All,

I am running the OpenJMS server on my m/c using "rmi_jms.xml"  as configuration file. I am not able to make connection to this server from a different machine. I am getting the following exception.

javax.jms.JMSException: Failed to locate server, url=//localhost:1099/OpenJMSServer: Connection refused to host: localhost; nested exception is: 
 java.net.ConnectException: Connection refused: no further information

Cannot connect to message server: 172.16.1.78:1099...

Can anybody tell what is wrong.
Do I have to change something in the configuration file before running the server so that it can be accessed from other machines.
