Hi Kero,
Can you give me an example of where Jess prints an exception rather
than rethrowing it? In general, exceptions from Java code are set as
the "cause" of a JessException, and rethrown. For example, any
exceptions that occur during a call to run() will be thrown from
run(). You can recover the original exception by calling getCause() on
the JessException object.

Hello!
We are writing unit tests around or software with JUnit and JMock.
When we run certain tests, Jess will call Java methods.
In the unit tests, JMock provides stubs for these methods.
With the expectations set, these method calls may raise an exception.
Jess catches this exception and prints it.
Thus, JUnit does not see the exception.
So when JMock flags a failure, our tests still pass.
A similar thing will happen in the deployed system, of course.
Is it possible to let Jess re-throw the exception?
We tried to find a flag to set on Jess, but could not find any.
We know that try/catch in Jess can install a handler, but we do not
know how to wrap such try/catch when we call Rete.run() from Java.
Other suggestions?
Bye,
Kero.
