Hi All,
Any ideas on how to scan a image using JSP, this jsp has to talk to some
methods.
2) How to save the image which is there in the frame, may be this has some
thing to do with applets.
Waiting for your response
Bye
Srikanth

This is working when both are on the same machine what about when the jsp is
running on a web tier and the ejb itself is deployed on different machine.
How do I connect my jsp with the ejb.
I've try using j2ee server but is not working.
Regards,
Mircea
