Subject [fileupload] - aborting file upload
Date Thu, 16 Nov 2006 02:42:04 GMT
Hi,

I am using commons-fileupload v1.1.1 on Websphere Portal v5.1. My file 
upload works as expected except when the file size exceeds the specified 
maximum size. 

parseRequest() throws a FileUploadException as expected, this exception is 
caught and processed appropriately and the code executes successfully. 
However the web page continues to churn, with the progress indicator 
increasing slowly. After 5 minutes the page displays the standard "This 
page cannot be displayed" error. And the stacktrace below is generated in 
the log. Has anyone experienced this or know of a way around it? Thanks 
for any advice.

A fragment of my code:

            DiskFileItemFactory factory = new DiskFileItemFactory();

            factory.setSizeThreshold(100*1024); 
            factory.setRepository(new File("C:\\temp\\"));

            PortletFileUpload upload = new PortletFileUpload(factory);
            upload.setSizeMax(1024*1024);

            Iterator itemsIter = upload.parseRequest(request).iterator();

            while (itemsIter.hasNext())
            {
 
                ....
                ....
                ....
        }

        catch (FileUploadException e)
        {
            System.out.println("**************************** FILE UPLOAD 
ERRROR");
        ...
        ...
        ...
            return;
        }
