If the client has JVM and permissions can be arranged to listen on a specific port (and any firewalls are going to allow the traffic etc) then: When sending your small form include a java applet that creates a task that simply listens on a specific port. Your asynchronous process can then return a message to that port.
This has been done. (with IBM MQSeries java API) Good Luck & regards, David. -- To unsubscribe: <mailto:[EMAIL PROTECTED]> For additional commands: <mailto:[EMAIL PROTECTED]> Troubles with the list: <mailto:[EMAIL PROTECTED]>
