}
catch(Exception e) {
e.printStackTrace();
}
}
The servlet.jar file is in server/lib directory. I am running on windows
xp machine.
Your help is appreciated.

One thing to ensure is that you're not trying to include servlet.jar inside your
webapp (since it's built in to Tomcat already). Including servlet.jar is
pretty much guaranteed to cause you very wierd errors, and this could certainly
be one of them.
On the other hand, it is important to include commons-fileupload.jar and any
JARs it depends on (see the docs) in your webapp's WEB-INF/lib directory.
