Hi friends,
i tried implementing the two jsp files(got from Commons FileUpload) as shown below But i got an error called "Http status 500"
This is my jsp code in the front end


UploadFiles.jsp
<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>

ProcessFileUpload.jsp
<%@ page contentType="text/html;charset=windows-1252"%>
<%@ page import="org.apache.commons.fileupload.DiskFileUpload"%>
<%@ page import="org.apache.commons.fileupload.FileItem"%>
<%@ page import="java.util.List"%>
<%@ page import="java.util.Iterator"%>
<%@ page import="java.io.File"%>
html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Process File Upload</title>
</head>
<%
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>

I deployed the above jsp using tomcat
i created 3 empty notepad files and tried to upload it
but i got the error as follows

org/apache/commons/io/output/DeferredFileOutputStream

This error is the key. Is that class in your commons IO jar? Is that jar in your classpath?
