Anonymous authentication is an additional feature that you need to create in
your web application. It doesn't come by default in any app servers. So there
is no need to disable it when configuring Tomcat.
There is a good article in JavaWorld discussing about anonymous authentication
in J2EE.
Without knowing the details of your problem (you may want to provide a
stack trace next time), I think the problem is in the java client. Did
you use JSSE to implement the client? The java sockets for accessing

You can't do this if both sites are on different machines since tomcat
user ID (defined as a cookie by default), is tied to an url. If both
