I am using rome-1.0.jar behind a http proxy, and running into problems. I have tried to export the http_proxy environmental variable, or use System.setProperty() to set the proxy host and port in Java, or supply them through -Dhttp.proxyHost and -Dhttp.proxyPort to java, and none of them worked. I read some people had similar experience in the past, and wonder if there is a known solution to this problem.
