Proxy setting

[GoogleCodeExporter]

Hi Nabeel,

Your application works well with the network without proxy. But when I
tried to use it in the network with proxy, it doesn't work. The following
exception is throwed:

I tried to set up the proxy, but it still doesnt work, something like this:
        Properties systemSettings = System.getProperties();
        systemSettings.put("http.proxyHost", "proxy");
        systemSettings.put("http.proxyPort", "8080");
        System.setProperties(systemSettings);

Do you have any hint???

Thanks in advance,
Quyen

Hi Quyen
Can you add this code and let me know if it works? (Note https instead of http)
systemSettings.put("https.proxyHost", "proxy");
systemSettings.put("https.proxyPort", "8080");

If this doesn't work I will try to setup a proxy at my end and debug it.

Regards

Hi Nabeel,

Just for your information:
-authentication process uses https protocol
-retrieving data uses http protocol

Cheers,
Quyen

Hi again,
Now i can connect to the proxy with HTTPS but i have a new error :-)

Caused by: java.io.IOException: Unable to tunnel through proxy. Proxy returns 
"HTTP/1.0 407 Proxy Authentication Required"

I must use my user name and password but i don't really know how to set these. 
I 
tried:
systemSettings.put("https.proxyUserName", "xxx");
systemSettings.put("https.proxyPassword", "yyy");
But it doesn't work even with http.proxyUser...

Ty.

Has to be reopened for the proxy authentication issue.
