B4J Question [ABMaterial] Use a application without the application path.

Hi, sorry if my question is ... I didn't find the answer here.

Normally I call an application with the correct port number and application name like this:

http://serverame:portnumber/AppName

Is it possible to call a "standard" application if there is no application name in the URL like this:

http://serverame:portnumber

I think yes (and hope) but how?

Thanks in advance.
