How to setup and invoke an EJB deployed on multiple remote servers from within another server instance

[bessen]

I followed the documenentation to set up outbound socket and outbound connection to invoke an EJB on a remote server from another server instance and it worked. Now I have a follow-up question. If I want to invoke an EJB deployed on JBoss remote server 1 and remote server 2 from server 0. What should I do? I need to set up two outbound socket bindings and two outbound socket connections? When I want to invoke the EJB from the JBoss remote server 1 or 2, should I do? How does JBoss server 0 knows which one to invoke my EJB call?

Hi Brian,

usually you would use an InitialContext ctx = new InitialContext(server1Properties) and new InitialContext(server2Properties) for that call.

There you can specify, which URL you want to use (connection to the server).

A different approach would be (in case you are in a cluster and want to call methods on all servers) using distributed MBeans (by using the cluster JMX notification). If you are interested in that, give me a short note on that.

Best regards,

Mark,

Thanks for your quick response.  I have tried to call EJBs from another JBoss 7.1.0.Final using your approach and it did not work. That was why I followed the instructions from the JBoss Web site:

https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+server+instance

  and it worked with one remote server. My question is if I want to make EJB connections to two or more servers then what I should configure and how I should connect to each remote server (EJBReceiver)?

Hi Brian,

try the https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI JNDI approach. It's more convenient, because you can supply properties. I'd propose also to give it a try specifying all the properties for the InitialContext(properties), there is a section about specifying EJB client context properties.

Best regards,

Mark
