Hi folks, Last week I posted the following question to the usenet group comp.lang.python but unfortunately I did not get any response. Sorry for cross-posting ... Ok here goes: I'm new to Jython - not to Python. The good thing about Python is that there are many packages available which can be installed easily by means of setuptools. Today I installed Jython, because I'm thinking of integrating some Python code into a web application which will be hosted on a web server with Tomcat behind it plus Jython. I found this webpage and followed the instructions about installing setuptools: http://www.jython.org/jythonbook/en/1.0/appendixA.html Unfortunately, it did not work for me. These are the errors I got: C:\TEMP\jython>java -jar D:\usr\lib\jython25\jython.jar ez_setup.py Downloading http://pypi.python.org/packages/2.5/s/setuptools/setuptools-0.6c11-py...

Any help will be appreciated. As you'll understand I'm using Windows XP ;-) Kind regards ... -- GMX DSL Doppel-Flat ab 19,99 €/mtl.!

Take a look ath the jython.bat, and you'll see the work that is done behind the scenes. It is not even close to java -jar jython.jar. |
