problem with running jpype with mod_python

As Python's urllib module is too slow, I'm using Java code wrapp开发者_如何学Pythoned with JPype in my web site. When I tested my web site with Django web server, there was no problem. However when I switched the web server to apache2 + mod_python, following error occurs. I googled many times but couldn't find the answer. Is there any solution to the error?

Another solution for your original problem: find other ways to get faster url retrieval.

httplib2 might already be a good solution: no problem to get it working as it's just a python library, but support for Keep-Alive connections can speed up things a lot, plus the caching support will help too (but only if you are often requesting the same url of course). And it's very easy to use.

If that doesn't get you far enought: PyCurl, the python binding for libcurl is probably the most obvious choice (there are also wrappers to make PyCurl easier to use, as PyCurl is apparently a bit low-level).

Anyway, just to say there are options that do not require java, that are easier to get working (and that will be probably end up faster as well)
