Technical Challenges / Resolution Implement high-performance file upload capability in servlet which parses HTTP request and supports Form-based POST method to automate file uploading to central server. Implement high-performance file upload capability in servlet which parses HTTP request and supports Form-based POST method to automate file uploading to central server. Resolution: To cut development time, researched on available open source solutions. Resolution: To cut development time, researched on available open source solutions. Commons FileUpload package from Apache was chosen because just a single method can be called to parse the servlet request, and flexibility to process the list of items later on.
