In jsp page the form field set as

<form name="frm" id="frmLoad" method="post" enctype="multipart/form-data">

isMultipart is printed as true(boolean isMultipart = FileUpload.isMultipartContent(request);)

       `out.println("Content Type ="+request.getContentType());` is printed as null

Write concise code and test it at your side or add fragement of servelt code and jsp code in your post. — KV Prajapati, Dec 07 '11 at 09:12

This exception indicates that either method="post" or enctype="multipart/form-data" is missing from the <form> element. But as they are apparently present, the cause lies elsewhere. Perhaps you're nesting forms, or misinterpreting the results, or not running the code you think you're running.

In any way, writing Java code in JSP files should be avoided. Use a servlet. You can find a concrete example in this answer: How to upload files to server using JSP/Servlet?
