I am trying to configure jms setup between two servers. The sender is on (server A)jboss 5 and the receiver is on (server B)jboss 4(which is using remote queue from server A.

When i try to run both on jboss 5 or jboss 4, it works. But when the receiver is on jboss 4 and sender is on jboss 5, then it throws below Exception.

Caused by: java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.jms.client.JBossConnectionFactory (no security manager: RMI class loader disabled)

Exception Trace:

I found below link which seems similar to the issue that i am facing but not able to get exactly on from which server to which server i need to have client libraries under war file?. https://access.redhat.com/solutions/45133

More Details:-

In my Case, jboss 4.0.4 and jboss 5.1.0 both are hosting the messages for different queues. -- jboss 5 is hosting the message and listener is on jboss4 for QueueA. -- jboss 4 is hosting the message and listener is on jboss 5 for QueueB.

What we want to achieve:- Jboss 4 on server A should communicate with RemoteQueues which are configured on jboss 5 on server B, which is not working and throwing above Exception. Communication is not happening between both servers.

  • So is JBoss backwards compatible ? If not, I guess there is no guarantee that a message published from JBoss5 will work with JBoss4. – Axel Podehl Apr 09 '19 at 12:07
  • Your question really isn't clear where the messages are being sent (e.g. to the JBoss 5 server or the JBoss 4 server), and you also don't make clear where the exception is being thrown. These are important details. – Justin Bertram Apr 09 '19 at 20:49
  • For what it's worth, the Red Hat article you linked is regarding RMI which is completely different from JMS. It really has no usefulness here. – Justin Bertram Apr 09 '19 at 20:51

The bottom line here is that JBoss 4.x uses JBossMQ as the JMS implementation and JBoss 5.x uses JBoss Messaging as the JMS implementation. The two are not directly compatible therefore you need to decide which server will host the messages.

If you want the JBoss 5 server to host the messages then all the clients (including those running on JBoss 4) will need to use JBoss Messaging client libraries.

If you want the JBoss 4 server to host the messages then all the clients (including those running on JBoss 5) will need to use JBossMQ client libraries.

If you're hosting messages on both JBoss 4 & JBoss 5 servers then the clients for each will need to use the corresponding client libraries for whichever broker their working with.

  • I have tried jboss 5 clients on jboss 4(including of 4) and jboss 4 clients on jboss5 (including of 5), but still i am getting the same exception mentioned in my question. – Ashok Apr 18 '19 at 05:36
  • jboss 5 is using all profile and jboss 4 is using default profile. – Ashok Apr 18 '19 at 05:44
