Proxy Server for Connection to WebEx Meeting Center
The WebEx server is always located outside the corporate firewall, and Windchill servers are usually located inside the firewall. Your site might require the use of a proxy server for HTTP connections through the firewall. To enable the Windchill server to connect to the WebEx server, modify the wt.manager.cmd.MethodServer entry in wt.properties. For example:
wt.manager.cmd.MethodServer=\

cmd.exe /C start "MethodServer" /MIN \

"$(wt.java.cmd)" -classpath "$(wt.java.classpath)" \

-Djava.protocol.handler.pkgs=HTTPClient \

-Dhttp.proxyHost=proxy.mycompany.com \
-Dhttp.proxyPort=8080 \
-Dhttp.nonProxyHosts=.mycompany.com \

-Xms32m -Xmx64m -Xnoclassgc -noverify
wt.method.MethodServerMain
The bold-faced entries are the required changes.
In this example the proxy server is located on host proxy.mycompany.com and is listening on port 8080. This proxy server is to be used for all HTTP connections, except those with host names ending in .mycompany.com.
