Javaranch tip:

If you are going to post more than a line or two of your code, wrap that
code in a set of UBB Code tags.
Doing so will help to preserve your code's indenting, making it easier to read.
If it is easier to read, more people will actaully read it and you will
stand a better chance of getting help with your question.
See UseCodeTags for more
help with UBB code tags.

Are you sure that your servlet is getting called???

Post your web.xml, if you can.

Moreover it seems you are not putting any logging system or System.out.println to debug. Without debugging the app you can never find whats wrong.

In the servlet, I don't see anything being sent to the client. No output, no redirecting, no forwarding. Maybe I should look again ?

In your servlet you can either call getServletOutputStream() or getWriter() method on the response object. You cant call both.
Since your jsp is also a servlet, and getWriter() will be automatically called by the container to provide you out implicit valriable. So you cant call getServletOutputStrem() in JSP. And using your out variable you cant send any binary data. So you cant process images in your JSP

Welcome to JavaRanch!

We're pleased to have you here with us in the servlets forum, but there
are a few rules that need to be followed, and one is that proper names are
required. Please take a look at the
JavaRanch Naming Policy and
adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.

You can change it here
 
I agree. Here's the link: http://aspose.com/file-tools
