Hopefully someone has had to deal with this before. I'm deploying two EAR files (isolated) that can only communicate through the remote interface. In order to enforce this I have set the JBoss Isolated and CallByValue options to true. When standard operating procedure happens things are normal. Entities serialize nicely and all is well with the world. On most methods in the remote interface there are multiple exceptions that can be thrown, each in a certain instance. However when they get back to the other EAR the catch blocks won't/can't recognise them. All are annonated with @ApplicationException and everything compiles okay. I have tried both including and excluding the exceptions from the client jar in the calling EAR to no affect. I am also unable to cast the exceptions to the correct class. Any help would be appreciated. Thanks, Grant The stack trace of the exception is below. | 13:41:36,684 ERROR [STDERR] au.gov.deh.ieda.bus.pitem.pd.exceptions.PimInvalidSearchTermException: Valid taxon must be greater than zero |
