Hi Deep,
As you can see am a "Green horn" to this forum and WS dev
"Greenhorn" doesn't necessarily mean you are new to technology, but new to Javaranch

.
Which class should I be calling - the Port class ?
Well, if you know your second web service is going to be on the same JVM as the first, you can call methods on endpoint interface (endpoint implementing class object) directly.
what are the implications if 1000's of requests need to be processed. Would the direct call as you said, be able to handle ?
This would be similar to any
Java application based on your design. Typically, those many number of threads are spawned by the JVM to serve incoming requests unless you have taken any special care on "synchronization".
Cheers,
Naren
