[Jython-users] jython2.5b1: demo problems

[Gregor L. <gre...@ao...>]

Hi all.
beeing new to Jython I've just installed jython2.5b1

Trying out the included demos I ran into several problems.
While some of the demos worked correctly, some produced
error messages, e.g.:

running Graph.py produces:

Traceback (...
  File "Graph.py", line 53, in <module>
    p = awt.Panel(layout=awt.BorderLayout())
TypeError: readonly attribute

and running simpe.py produces:

Traceback (...
  File "simple.py", line 14, in <module>
    frame = awt.Frame('AWT Example', visible=1)
        at org.python.core.PyObject.__tojava__(PyObject.java:257)
        at ...

           nine similar lines alltogether

        at 
org.python.core.PyObjectDerived.__setattr__(PyObjectDerived.java:1026)

java.lang.NullPointerException: java.lang.NullPointerException

Several (but not all) examples from the applet directory produced 
similar error messages.

So I wonder if there something went wrong with my installation. I'm 
using jre 1.6.0_11. On the other hand these demos run without problems 
when using jython 2.1.

What do you think? Are these problems caused by an imappropriate 
installation or are they a beta-1 instability - in which case they 
probably should be reported to some different mailing list?

Regards,
Gregor
