applet-to-servlet : making it work ...

[achana chan]

Hi again.
After one week I am still trying to set up an HTTP URLConnection to the applet and "tunnel" thru to Tomcat. I have researched several sites and books, using Karl Moss's "Java Servlet Developer's Guide" as a principle source of examples. I have even paid a big company to help out only to be told they do not support Apache/Tomcat.
I have not been able to establish reliable sessions.
My Apache seems to be collaborating well with Tomcat , http://MyServerName/com/ServletName will retrieve data from db-server and display on browser. Works find like that.
However, when I try to "tunnel", that's when I get these errors from the JAVA console :
