Hi, guys: Here is the scenario: I have a Websphere server whihc sits on a remote machine, I will create a file on the server machine's local file system. Multiple clients (on different machines) will send request ids to populated that file to form a queue of request ids. Now, I have another main client ( on another machine) which will send request to the websphere server to poll if that file containg a queue of request ids has new ids filled. The server has no ability to send events to the main client, so, the client has to constantly poll the server to see if new ids filled. If there new ids, the main client will retrieve them from the server. This is kind of new to me. My question is: we usually have the client/server structure with a running server waiting for client requests; if this is a web server such as Websphere, how does the main client send requests and poll the queue on the web server's local file system? Thanks a lot.
