Java EE (Java Enterprise Edition) General Discussion

Hi Friends,

I am developing a small web application using jsp, spring, and tomcat 5.0. In my application i need to to up-load one file at add page. it also contains some form fields. In servlet i am using the multipartformdatarequest. its work fine when i am running it locally. but it gives exception when it runs on the main server on uploading.

code i used for parsing the MultiPartFormDataRequest is :

public ModelandView addFile(HttpServletRequest request,HttpServletReqponse response)
{
      MultipartFormDataRequest mrequest = null;
     if(MultipartFormDataRequest.isMultipartFormData(request))
     {
            try
            {
                     mrequest = new MultipartFormDataRequest(request);
             }
             catch(Exception e){
                      e.printstacktrace();
               }
      }
}

the code inside the try block generates an exception. so i m not able to get the mrequest object for further operation. This code sometime work fine. but most time it fails.

the exception stack trace is :
