Hi Martin, I'm not sure why you are getting the exception. As far as I know, what you are attempting should work. I would recommend moving the <AutoWebApp> out of the <Host> declarations an putting them in server.xml. I believe they will still do what you expect if placed there. I don't know if there are side effects if you try to use it context local.
There should be separate work directories created for both virtual hosts. Each should compile its own numguess.jsp. Try setting the debug level on <SimpleMapper1> to 1 and check the log for "Host = ..." and make sure the request is going to the virtual host you expect. I'll see if I can try some experiments and see if I can duplicat this when I get a chance. Cheers, Larry > -----Original Message----- > From: Martin v.
