Tip: The mapping configuration for the Community Services connectivity<br />

should contain two case-sensitive mapping rules as indicated here. Some<br />

pieces of the Java code contain the lowercase “c” in “communityCBR” and<br />

some pieces of the Java code use the uppercase “C” in “CommunityCBR.”<br />

This difference may prevent connections if the proxy is case-sensitive.<br />

Example mapping for Meeting Services<br />

This example illustrates the mapping configurations that enable a Java applet<br />

client to connect to the Meeting Services.<br />

If the incoming URL from the Java applet is:<br />

http[s]://proxy.ibm.com/st01/MeetingCBR<br />

the mapping rule on the reverse proxy must translate this URL to:<br />

http://sametime.ibm.com:8081/MeetingCBR<br />

Example mapping for Broadcast Services<br />

This example illustrates the mapping configurations that enable a Java applet<br />

client to connect to the Broadcast Services.<br />

If the incoming URL from the Java applet is:<br />

http[s]://proxy.ibm.com/st01/BroadcastCBR<br />

the mapping rule on the reverse proxy must translate this URL to:<br />

http://sametime.ibm.com:554/BroadcastCBR<br />

HTTP tunneling simplifies the Java applet mappings<br />

During a Sametime server installation, the administrator has the option of<br />

allowing or not allowing HTTP tunneling on port 80.<br />

If the administrator does not allow HTTP tunneling on port 80 during the<br />

Sametime server installation, it is necessary to configure separate mapping rules<br />

for each of the three Sametime services (Community Services, Meeting<br />

Services, and Broadcast Services) as just shown.<br />

When HTTP tunneling on port 80 is not allowed, each of the Sametime services<br />

listens for HTTP connections on a different port, and separate mapping rules<br />

must be established for each of the services. The mapping rule must specify the<br />

port on which each of the services is listening for connections.<br />

If the administrator allows HTTP tunneling on port 80 during the Sametime server<br />

installation, the Sametime clients connect to all of the services on a single port.<br />
