Programmatically Determine Connector Port Numbers etc.

Hi

I am writing a custom JSP tag and I need to be able to determine how
the servlet container is configured. Specifically, I want to be able to
do things like get a list of the port numbers in use and which schemes
they are using (e.g. HTTPS on port 8443).

Is this possible?

I know I can manually read my server.xml file or whatever, but I need
the JSP tag to be able to ask the servlet container.

Your advice would be appreciated.

Generally that sort of stuff is considered none of your business and
Java does not give you hooks to find it. I take it you have looked.

This leaves you next studying the native API looking for some C++
access to what you want. Then you can build some JNI glue to get what
you want.
