Actually it&rsquo;s not an issue that stems from TMG itself but the way TMG server is configured (using authenticated rules on TMG server) triggers the problem. en-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.technet.com/b/nettracer/archive/2011/09/21/java-applications-and-tmg-access-rules-that-require-authentication.aspx#3454935Thu, 22 Sep 2011 13:48:21 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3454935MuratKa1<p>Thanks for the feedback Richard.

The Firewall Client authenticates to the TMG firewall transparently. The application is unaware that it is communicating through an authenticating proxy.
