Ajay,
I suspect you don't actually get a JMS ConnectionFactory with the JNDI
configuration you have there. Could you check the JNDI configuration
and especially the name for the your ConnectionFactory? Also, could you
try using the new <jms:provider/> endpoint to see what exception that
gives you?
Regards,
Gert

hi,
Iam having the same problem again and again. I really dont know how I can
get rid of this problem when I use JNDI template. Iam using camel basic
example.

Camel MyRouteBuilder.java
public class MyRouteBuilder extends RouteBuilder {
public void configure() {
//send a message to a JBI endpoint...
from("timer://tutorial?fixedRate=true&delay=3000&period=30000")
// 1
.setBody(constant("<message>Hello world</message>"))
// 2
.to("jbi:endpoint:http://intra.agfanet/jms/myProvider1";);
}
}
My intension is to write on a queue name queue/testQueue. So that the
messageDrivenBean deployed on Jboss gets this message. But, Iam having the
following errors and exceptions.
