[Jython-users] Re : Embedding Jython, where do error messages go?

[Sébastien LE C. <sl...@ya...>]

Hi Joonas,

As far as I can see, Jython throws a PySyntaxError
when there's a syntax error in the script, so you would have to catch
the exception thrown by interp.execfile, and print the stack trace to
your console in the catch.


Regards,
Seb

But if the script contains an error, the interpreter doesn't seem to give any error messages - it just stops. I think it's supposed to give some feedback, though.
