[Jython-users] Problem with throwing java exceptions

[Chris A. <at...@nm...>]

I am having problems throwing a java exception from my jython code and
catching it in java.

I have the following class structure:

SomeIF.java
    ^
    |
SomeImpl.java



SomeIF.java
    ^
    |
BaseImpl    -- python class
   ^
   |
SpecificImpl - python class


BaseImpl looks like the following:
class BaseImpl(SomeIF):
  def __init__(self):
    pass

  def prehook(self, arg1, arg2):
    raise JException(arg2, "msg")

  def posthook(self, arg1, arg2):
    return None

when BaseImpl.prehook() is called, my java code gets the exception as a
JException.

Specificmpl looks like the following:
class SpecificImpl(BaseImpl):
  def __init__(self):
    pass

  def prehook(self, arg1, arg2):
    raise JException(arg2, "msg")

when SpecificImpl.prehook() is called, my java code gets
org.python.core.PyException

Just for grins, I placed BaseImpl and SpecificImpl in the same module.

Both exceptions are caught by the same method which has the following code:
public void extest(SomeIF impl) {
  try {
    impl.foo();
  }
  catch(Exception e) {
    System.out.println(e.getClass().getName());
  }
}

I am creating the instances of BaseSomeImpl and SpecificSomeImpl in the
jython interpreter and passing them to my java code.

Any thoughts on what might be wrong?

Thanks,
Chris
