One tool that can help in debugging applications is the logging mechanism. You can perform both client-side and server-side logging. Client-side logging writes log messages from the Flex client to a file on the client computer. Server-side logging writes log messages from the BlazeDS server to a designated logging target, which can be the log location for the servlet container, System.out, or a custom location.
