hi Deniz
Try this one out:
use the service() method to trap u r data from the applet. Then use
encodeURL() method of HttpServletResponse .... this method takes only the
name of the new url that u want to open.
Else in ur showDocument() method from the servlet pass the session variable
as a parameter
best of luck
