Most likely a defect in the Java classlib you're using. Other possibilities include a buggy JNI component or (less likely) someone trying to hack their way past the sandbox. This is Java's security mechanism telling you that you have data of the wrong type for the code expecting to manipulate it.

thanks for your reply.
i am using 2-3 other servlets in the same context and they are working.
the method the error talks of is used to get the system date and store it in a certain format.
do you think that could be the problem.
I agree. Here's the link:
