I had written a file upload application using
jsp and
servlets using apache.commons.fileupload package. The application uses port 8080 to upload files to server (in a particular folder). I checked the application with 790 MB rar file uploading. It's working. Try to wrtie a servlet that upload the files using apache.commons.fileupload package (can be downloaded from apache's site). even if the firewall is on the application can upload file through port 8080 of
Tomcat server. Hope you will be able to write the code to upload the file, else you can ask for the application code to me.
