Dear Carlos, haven't used mod_wsgi so far, but remember there was a patch submitted to the list related to mod_wsgi :

If there is interest, I can further > clarify. > > Pat That hasn't been discussed further, but maybe Pat can comment on what the patch was good for or what problem it solves? BTW, the error you encounter may not be related to the python interpreter not finding jcc.dll but rather that jcc.dll cannot be loaded in the current process - e.g. because of wrong path in environment. I can for example reproduce this by setting PATH=C:\ and invoke python: Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import jcc Traceback (most recent call last): File "<stdin>", line 1, in <module> File "c:\Devel\Python27\lib\site-packages\jcc-2.13-py2.7-win32.egg\jcc\__init__.p y", line 31, in <module> from jcc import _jcc ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden. >>> A typical problem in not being able to import lucene/jcc is a missing DLL (msvcr71.DLL) which is required by the loaded DLL. Sometimes it helps to load the DLL directly - in a command shell (interpreter) environment for example a windows dialogue may popup and tell you about the missing DLL. That may not work in a server process... Hope that helps. Regards, Thomas > -----Ursprüngliche Nachricht----- > Von: Carlos Ferreira [mailto:to.carlos.ferre...@gmail.com] > Gesendet: Donnerstag, 16.
