I have configured a proxy in my java source code as:

systemSettings.put("http.proxyHost", "www.proxyserver.com");
systemSettings.put("http.proxyPort", "8080");
systemSettings.put("http.nonProxyHosts", "10.x.y.z");

Here 10.x.y.z is the actual IP of my weblogic server.
But whenever code tried to connect to weblogic server, I receive error as:

Caused by: java.net.ConnectException: t3://10.x.y.z:7001: Destination
unreachable; nested exception is: java.net.ProtocolException:
unrecognized response from proxy: ‘HTTP/1.0 403 Forbidden’; No

It seems that setting http.nonProxyHosts is not working as expected. I tried to find solution over the Internet, but most of them says remove proxy settings. I can not remove proxy, as my code tries to connect to some of the Internet URLs. Also note that, weblogic server is on remote machine.
Can you please give me a hint, what must be the issue here?

    I resolved the issue. I had setup the proxy initially when connection with weblogic was setup. So due to some network restrictions I believe it didnt work. In modified code, I used the same 3 lines to setup proxy:

    System.setProperty("java.net.useSystemProxies", "false");
System.setProperty("http.proxyHost", "www.proxyserver.com");
System.setProperty("http.proxyPort", "8080");

    The only difference is, I did it at exact place where I needed. So for initial connection setup with weblogic proxy wont be used. I also did not have to bypass, weblogic server URL to not to use proxy.

    @Arcadien: I appreciate your efforts to help me. Thanks.
