Re: FileUpload - read timed out / stream ended unexpectedly

[Brian Cook]

It sounds like the file attachment fields in your HTML are being left 
blank.  I.E. the user is clicking the submit button with out attaching a 
file.  This returns the file parameter(or item) as blank and throws a 
FileUploadException.

You will need to throw in a condition to check to see if the file name 
is blank and if so not call the method that does the uploading.

Example:

   // Read the parameter/item that should hold the file name
   String itemName = item.getName();
   // Check to see if the file name is blank.
   // for some reason doing an if compare to null did not work for
   // me
   if(itemName.length()<2)
   {System.err.println("Oppsss no file to upload");}
   else
   {			// Open else in readParam method
        System.out.println("If triggered");
        File fullFile = new File(itemName);
        File savedFile = new 	 
File(getServletContext().getRealPath("/"),fullFile.getName());
        item.write(savedFile);
        System.out.println("Ok, the file should have been written 
somewhere....");
   }  			// Close else in readP
