Managing a deployed CEP application

Question

Hi all
After the CEP server managed to deploy and start my application, I have a few initialization steps to perform myself (reading configuration file, etc.). I want to be able to undeploy the application in case any of these steps fail.
I tried using the code example found on the AppDeploymentMBean documentation ( [http://download.oracle.com/docs/cd/E12839_01/doc.1111/e14303/toc.htm] ), but I keep getting a - java.net.ConnectException: Connection refused: connect - exception from the connect method on the second line.
I don't have much experience with JMX or management beans, so I'll appreciate any help you can provide.
Also, If you think there's a better way to perform this, I'd like to hear it.
Thanks,
Roy

Hi Roy,
CEP is built on Spring DM. Thus the spring bean lifecycle and OSGI lifecycle apply to a CEP application. Beside that, we also support CEP specific lifecycle management.
Here is an instruction for it:
1) spring lifecycle interface:
InitializingBean, DisposableBean
2) osgi lifecycle interface:
You can implement your own activator to start/stop your application. You need to implement BundleActivator
3) cep lifecycle interface:
This might be what you want.
In order to process application configuration, you can use @Prepare, @Activate @Rollback.
spring-like lifecycle interfaces: RunnableBean, ActivatableBean,SuspendableBean,ResumableBean
As for the detail please go through the CEP docs.
