Completing this procedure saves proxy preferences in the user's messenger.properties file. If you also configure the im.jnlp file to use a proxy, and the proxy differs from that in the user's preferences, the user's preferences are used.
Invoke Java Web Start.
From the File menu, choose Preferences.
Select Manual option in the Preferences dialog.
Enter the following details:
HTTP Proxy. Enter the Name or the IP address of the proxy server.
HTTP Port. Enter the port number of the proxy server.
No Proxy_Hosts. Enter the name of any domain that you can connect directly, bypassing the proxy server. Use commas to separate multiple host names.
Click OK to save the proxy settings.
