Hi, In our company, we access internet through a http proxy server (with user name and password). One of my EJB3 application needs to access outside web service. But I don't know how to set up jboss, so that it realizes the existence of the proxy server and uses it. Because of that, I am getting a "Caused by: java.net.UnknownHostException" exception. It is greatly appreciated if someone can help. Thanks in advance. Peter View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4184915#...
