Hi There,
i am trying to establish a connection to a certain url using a notes java agent. I have managed to write some code that works as a standalone app but as soon as I introduce the code in a notes agent I get the following error:
java.net.UnknownHostException: www.ibm.com
java.net.UnknownHostException: www.ibm.com

System.out.println( e );
