one solutionn to this, but it might not efficient. Before you execute the method call to your COM server, put a Thread.sleep(your_interval) to pause the execution for a couple milliseconds, this will force the call to be delayed. For my opinion, the middleware queueing concept is a good idea, but it takes time to be implemented. Hope this helps.

It's all happening asynchronously (?) with little control on the Java side -----Original Message----- From: James Stauffer [mailto:[EMAIL PROTECTED]] Sent: 21 January 2003 15:10 To: JDJList Subject: [jdjlist] Re: Slowing down processing Out of curiousity why do you want to throttle the method calls?

I suspect I am going to have to create proxy objects to put in the queue that understand their own parameters, return values and timeouts. It would be nice if you could queue a function call.
