Using Spring JMS DefaultMessageListenerContainer within Oracle CEP

Question

Hi everyone,
I need to use a DefaultMessageListenerContainer Spring bean (from spring-jms.jar), have the wlevs bean factory to assemble it (it depends from a POJO) and set it as a property of an Adapter bean.
How do I do it?
I tried to put the spring-jms.jar into the xbootclasspath but it depends from spring-core.jar. If i put spring-core.jar into the xbootclasspath, the server dies screaming.
Documentation says i can use legacy Spring beans within an OCEP application, well how do i do it? Can anyone tell me the right steps to do?

Answer 1

Thanks for the answer :), i just had to import the appropriate packages into the MANIFEST.MF, put all the classes referring to spring-jms into the bundle and away i went.
The application starts, listens to the JMS destination (an Oracle AQ queue) and dequeues messages correctly.
I still have a problem when i try to suspend/uninstall the application from the OCEP visualizer.
The JMS listener is encapsulated into an OCEP ResumableBean/SuspendableBean. It gets created and started (with a call to DefaultMessageListenerContainer.start()) within the beforeResume() method. I hoped that putting a call to DefaultMessageListenerContainer.shutdown() within the suspend() method would do the trick but... the undeployment hangs for a while, then the following is printed on stdout:

I also tried a call to DefaultMessageListenerContainer.setTaskExecutor passing it an anonymous class like this:
container.setTaskExecutor(new TaskExecutor() {
@Override
public void execute(Runnable task) {
logger.debug("Submitting runnable task");
executorPool.submit(task);
where executorPool is an instance field of the OCEP bean initialized like this: executorPool = Executors.newFixedThreadPool(8);
Anyway the result is the same, when i perform the uninstall from the OCEP visualizer the application is undeployed, but with the same painful message.
Any hint on what i'm doing wrong?
Thanks in advance!
