[uploadfile]

[Guojun Zhu]

I am using netbean 5.5beta2 with tomcat 5.5.17 for a jsp. 
 
I keep getting error like this
 
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from 
fulfilling this request.
exception
org.apache.jasper.JasperException: Exception in JSP: /index.jsp:51
 
48: ServletFileUpload upload = new ServletFileUpload(factory);
49: 
50: // Parse the request
51: List /* FileItem */ items = upload.parseRequest(request);
52: %>
53:   
54: 
 
I have put the common jar file in the web-inf directory of the web 
subdirectory, where index.jsp sits.    It complies fine.  The jsp works file 
without revoking by the form query.  

Here is the file invoke the jsp 

   
 
  <form name="tt" action="index.jsp" method="POST" 
enctype="multipart/form-data">
      <input type="text" name="text" value="" />
      <input type="file" name="file" value="" />
      <input type="submit" value="submit" name="submit" /></form>
 
 
Here is the jsp code
