Yes, I tried it.
If I don't let the service method to return it works. I just don't want the
streams to go out of scope.
Most of the examples of applet servlet communication need to create the
URLConnection object everytime I send a object. If I don't let the service
method return (of course on certain conditions & not always), I can send as
many objects as I can with jus one connection.
I hope this should work!!!
Any comments??
Best Regards,
Rahul
