Nested exception from ejbStore

Question

I am throwing applicaton exceptions (subclasses of RuntimeException) from ejbStore - in case an update to the database fails because a unique constraint was violated. I get a weblogic.transaction.RollbackException back. I tried to use the getNested()method, but my import of the RollbackException class failed in compilation, even though the compilation classpath includes weblogic.jar. Also, I'd prefer not to use a vendor-specific exception if possible. When throwing the same application exceptions from ejbCreate, it was possible to catch a RemoteException and get the nested exception out of it. Thanks for any help!

Answer 1

First, an application exception is hardly a subclass of
RuntimeException. Application exceptions should derive from
java.lang.Exception and for those the container would just throw the
application exception to the caller. If you want to rollback the
transaction you can do so by doing EjbContext.setRollbackOnly() and then
throw the exception.
Having said that you should still be able to extract the underlying
exception from the javax.transaction.TransactionRolledbackException the
container throws (I haven't heard of
weblogic.transaction.RollbackException and even if such exists it should
be a subclass of TransactionRolledbackException) by doing exception.detail .
I've had some problems in 6.0 as in some cases it does not include the
underlying exception but in 6.1 and probably in 7.0 (haven't used it a
lot) it work fine.
