Hi Kaustubh,
Thank you very much for the info. But there are some issues.
Imagine I have declared a variable in first servlet and instanciated in
the init method.
but when I try to use that variable in the second servlet, it would give
me a compile time error saying that variable is undefined.
Secondly I need the request and response object for the JNI function
(which i intend to call in init() method) and which is not available in
the init() method.
If you need any more explanation on this pl mail me.
Kindly help
Regards,
San.
