How do I enable logging?

Check out the Logging page.

Using a proxy

It is recommended that the user set JVM arguments to configure this application for their proxy.

https.proxyHost      Hostname of proxy server                      web-proxy
https.proxyPort      Port on server of proxy                       8080
https.proxyUser      Optional username for proxy authentication    someone
https.proxyPassword  Optional proxy server password                secret

These properties can be set with JVM args in your Eclipse run configuration:

-Dhttps.proxyHost=web-proxy -Dhttps.proxyPort=8080 -Dhttps.proxyUser=someone
-Dhttps.proxyPassword=secret ...

If necessary, set this up in code by doing the following:

System.setProperty("https.proxyHost", "web-proxy");
System.setProperty("https.proxyPort", "8080");
System.setProperty("https.proxyUser", "someone");
System.setProperty("https.proxyPassword", "secret");
