Here is the sample code I am trying to run from http://www.theserverside.com/tt/articles/article.tss?l=HttpClient_FileUpload but keep getting the errors:

Listing 9-4. UploadFiles.html
<HTML>
  <HEAD>
    <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=windows-1252"/>
    <TITLE>File Upload Page</TITLE>
  </HEAD>
  <BODY>Upload Files
    <FORM name="filesForm" action="ProcessFileUpload.jsp"
    method="post" enctype="multipart/form-data">
        File 1:<input type="file" name="file1"/><br/>
        File 2:<input type="file" name="file2"/><br/>
        File 3:<input type="file" name="file3"/><br/>
        <input type="submit" name="Submit" value="Upload Files"/>
    </FORM>
  </BODY>
</HTML>

        System.out.println("Content Type ="+request.getContentType());
 
        DiskFileUpload fu = new DiskFileUpload();
        // If file size exceeds, a FileUploadException will be thrown
        fu.setSizeMax(1000000);
 
        List fileItems = fu.parseRequest(request);
        Iterator itr = fileItems.iterator();
 
        while(itr.hasNext()) {
          FileItem fi = (FileItem)itr.next();
 
          //Check if not form field so as to only handle the file inputs
          //else condition handles the submit button input
          if(!fi.isFormField()) {
            System.out.println("\nNAME: "+fi.getName());
            System.out.println("SIZE: "+fi.getSize());
            //System.out.println(fi.getOutputStream().toString());
            File fNew= new File(application.getRealPath("/"), fi.getName());
 
            System.out.println(fNew.getAbsolutePath());
            fi.write(fNew);
          }
          else {
            System.out.println("Field ="+fi.getFieldName());
          }
        }
%>
<body>
Upload Successful!!
</body>
</html>

but I keep getting the following error:

Can someone tell what am I doing wrong. I have commons-fileupload-1.1.jar in my classpath. I even tried someother samples but keeps getting the same error
i.e. parseRequest(request); I really want to upload an xml file only and read it's content from memory in the servlet and do the processing. Any help is appreciated.

Thanks

The org.apache.commons.io package is not part of commons-fileupload-1.1.jar.

Thanks, How can I make sure that uploaded file is xml file. I want to upload only xml files. Is there a way that I can restrict upload of files to certain types. Thanks
