RE: [openjms-user] RE: Object Messages

The com.surfkitchen.proxy.logging.LogBean class needs to be in 
the same or parent class loader to that of the openjms jar.
 
If you include the openjms jar in your webapp, along with
the jar containing LogBean, the problem should go away.

Subject: [openjms-user] RE: Object Messages



Hi,

I am developing a logging application which is sending ObjectMessages to a
Jms queue. I am targeting JBOSS 4 where the application seems to run fine
within JBOSS JMS server. However I also have to support Tomcat / openjms
configuration.

 

At the moment I am getting a Class not found exception on the queue listener
class. The class not found it refers to is within the war file deployed.
Connection to JMS is being done through tcp connector.

The object sent is serialised ok. Does anyone have any experience with
something like this ?

 

Thanks

 

Ben
