http Status 500

Help I'm looking to find a fix for webapps running on a tomcat with IIS6 running on it too. Why am I getting this message.

HTTP Status 500 -

Have you tried the simplest thing? Reading the error message that you get!
It clearly says:
java.lang.ArrayIndexOutOfBoundsException

Somewhere in your code you are using an index that is too large or too small. It is like trying to access an array with an index greater than its length. Try reading the whole message until you find the first class or file that you have created(that it is yours). The message says the line where the error occurred.

Or you may be accessing an empty array...

Somewhere your code is getting null value or instance of object, you need to debug code better
