[Jython-users] Missing Lib files in post 2.0 versions of Jython

[Adam K. <AK...@ma...>]

I noticed that the most recent distributions are missing lib files like
zipfile.py and zlib.py, but older distributions had it.  Is there some
reason for this?

Subject: [Jython-users] Running jythonc classes from web server cgi


	I seem to be having a strange problem when I call a jythonc-compiled
jython program from a cgi. The program will run correctly if i "su -
nobody" (the server runs as nobody) and execute it by hand, but when I
try to call it from a cgi python script, I get the following error in
the apache log:

ValueError: insecure string pickle

ValueError: insecure string pickle




Apache 1.3.20 (custom compiled)
Python 1.5.2
Jython 2.1a3
Sun JDK 1.3.1_01
Redhat 7.1
Linux 2.4.7 (custom compiled)



	What I am essentially trying to do is this:

1) A Python/GTK program is used to generate, and then pickle data in the
python format

2) A Jython program is then used to unpickle the data, convert to Java
data, and export a Java serialized file

3) A Java Applet reads in the serialized file.



	I don't have a problem with any of this unless I'm running it on the
web server. I am running jythonc-compiled files because the web host
does not have jython installed. I am doing the conversion through CGI
because both the applet and the PyGTK program are GPL, and I can't
distribute jython.jar with GPL'd code, because I don't believe it's
compatible with the GPL. I figure that I can code the PyGTK program to
attach to the website and automate the conversion process remotely, and
since I'm not distributing the jython.jar, everything is kosher.



	If anyone has any pointers offhand, please let me know. If posting
some
or all of the code would be helpful, just let me know.

	Thanks a lot guys.
