The document discusses using Flex and Java Servlets to implement file uploads. It provides an architecture that uses RemoteObjects to enable communication between the Flex and Java components. The Flex interface allows users to select a file to upload, and displays upload progress. The FileUploadServlet on the Java side handles the actual file upload using Apache Commons FileUpload library.

This binary protocol uses Java classes directly to provide data to Flex. The RemoteObject component uses HTTP to transport binary ActionScript over the communication channel.RemoteObject Protocol
