Integration

Hi guys, I installed iplanet web server on windows xp. I have some jsp files which were working correctly with apache. Later when i try to open a jsp file, http://localhost/myfolder/index.jsp, with sun iplanet web server, i get the following error message:

Server Error
This server has encountered an internal error which prevents it from fulfilling your request. The most likely cause is a misconfiguration. Please ask the administrator to look for messages in the server's error log.

Then according to this message i saw the error log and get the following:
