[Jython-users] com.python.compiler.JavaMaker -NoClassDefFoundError

[Brian P. <bp...@wi...>]

I'm compiling to class files like this:
jythonc --core --deep --jar my.jar *.py

If I look in the jar, sure enough, the whole compiler "package" is not
there?  Any idea what I might be doing wrong? (The code runs fine
through "jython".)

Java Traceback:

[Jython-users] Jython/Python Question

[chuck c. <cc...@zi...>]

I checked out the FAQ and the Jython vs. CPython docs and wasn't able to
find an answer to the following.  I have this code:
def test():
    print noname

try:
    print "line 5"
    print "line 6"
    test()
    print "line 8"
    print "line 9"
except ValueError:
    print "shouldn't happen."

When I run it under python I get the following stack trace:
line 5
line 6
Traceback (innermost last):
  File "test.py", line 7, in ?
    test()
  File "test.py", line 2, in test
    print noname
NameError: noname

Under Jython I get:
line 5
line 6
Traceback (innermost last):
  File "test.py", line 10, in ?
  File "test.py", line 2, in test
NameError: noname

I lose some granularity in Jython.  If I were to call the extracted method
(test in this case) several times within the try block I can't tell on
which line the failing call resulted from.  It always reports from the
except line.  Why is this?  Is it the expected behavior?

cheers
chuck

It is a bug. I have added a bug report about it and expect a fix to be
included in beta1. 

Thanks for reporting it.

you need --all to get the compiler and parser. Try:

jythonc --all --jar my.jar *.py

(--all implies --deep).
