Hi,
i want to use RMI to start/stop jobs in my application. The following line throws an UnmarshalException:

Code:

JobDetail job = scheduler.getJobDetail(key);

Exeption:
Code:

Caused by: java.rmi.UnmarshalException: error unmarshalling return; nested exception is: 
 	java.lang.ClassNotFoundException: de.csconnect.udb.business.dienste.impl.TestJob
 	at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:178)
 	at org.quartz.core.QuartzScheduler_Stub.getJobDetail(Unknown Source)
 	at org.quartz.impl.RemoteScheduler.getJobDetail(RemoteScheduler.java:720)
 	... 2 more

I know that i cannot access the class TestJob (different codebase), but all i want is to use its interface JobDetail. Is there a way to tell RMi just to unmarshall the interface? Any other idea how this problem may be solved?

Thanks Björn

No, RMI does not work that way.

The FAQ has links to some RMI references, also there are many out there if you just google.

Hi,
thanks for the quick answer, suddenly i realize you only need the interface of the service, but the implementation of the passed objects. So there is no way to write an app that starts/stops jobs via rmi without having the same codebase, right? Is there an other technique i might use?
