Programatically reading browser proxy settings & authentication

hi,doesn anyone know to read the default browser proxy settings while proxy requires authentication? I would have to set the proxy address together with username and password to a XFire client... and would have to extract them somehow somewhere.

Nevermind about this, I managed to figure out a workaround. This was actually question about XFire and Commons HTTPClient -- it seems that java web start is unable to pass on proxy information to Commons HTTPClient. Instead using java HTTPUrlConnection worked with proxy authentication, so I'm content with this solution, at least so far. Seems to be a "feature" in commons package.
