Hi Christopher and Derik,
thank you for your messages. I am using the same build-area for some
time already. It dates Kepler 2.2, or maybe even earlier... I recall
now, that there was a request to use build-area-2.3 some time ago -
maybe this is the problem? I will redo my tests with it later this
week and report here if it helped.
Thanks, regards,
Tomek

Just another datapoint: I was also able to 'Instantiate Component'
ptolemy.actor.lib.python.PythonScript in kepler-2.3 and kepler trunk.

Hi Tomek,
I just checked Kepler-2.3 and the Kepler devel trunk and I was able
to instantiate
the Python actor.
PyJavaInstance should not be present in the Kepler devel trunk. I
did the update
to Jython-2.5.2 on November 5, 2011, which is when I edited
ptolemy/actor/lib/python/PythonScript.java and removed the use of
PyJavaInstance,
Can you check your copy of PythonScript.java and make sure that it
does not use
PyJavaInstance?
Also, when I looked at your log, I see that the path to the Ptolemy
II tree was:
/home/tzok/code/kepler-codebase/ptolemy/actor/lib/python/PythonScript.xml
In my devel tree, this would be something like:
~/src/kepler/ptolemy/src/ptolemy/actor/lib/python/PythonScript.java
Note that my Ptolemy II tree is in "ptolemy/src", whereas yours is
in "ptolemy".
The error message says "PythonScript.xml" because MoMLParser was looking
for a MoML class, which would be defined in a .xml file. This is
not a problem.
Perhaps you have an old development tree?
Here are the tests I ran.
Note that PyJavaInstance is *not* present in the PythonScript uses
in my Kepler devel tree, but
it is present in the PythonScript in Ptolemy II 8.0.1.
bash-3.2$ grep PyJavaInstance
~/src/kepler/ptolemy/src/ptolemy/actor/lib/python/PythonScript.java
bash-3.2$ grep PyJavaInstance

sorry for double post.

Hi,
I am aware that this topic is few months old, but I would like to
reopen the
discussion. It seems that the current version of Kepler is still
not working
with Jython 2.5.2
First of all, I have my Kepler from trunk (with Ptolemy set to
HEAD revision)
and it is up-to-date. Here is my Jython version:
$ java -jar ptolemy/src/lib/jython.jar
Jython 2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06)
[OpenJDK 64-Bit Server VM (Oracle Corporation)] on java1.7.0_03-icedtea
However the actor ptolemy.actor.lib.python.PythonScript does not
work. When I
try to instantiate it, I get the following error: (a more detailed log is
attached)
java.lang.NoClassDefFoundError: org/python/core/PyJavaInstance
>From the discussion I assumed there is a workaround implemented
in Kepler to
use PyJavaType.wrapJavaObject instead of PyJavaInstance, but the
error I get
indicates the opposite. So what is the status of PythonScript
actor? Is this
update to Jython 2.5.2 supported?
Best regards,
Tomek
