I don't know if this is documented but you can change the java download location that comes up in the meeting room. In the new MRC it does a Java check before entering room and if you don't have correct version it says "The version of Java installed on this machine is not supported. To continue, click here to install an updated version, " which goes to Sun download site. Although helpful having this link it confused some users and we had already created a custom package for Java anyways. So if you want to change this go your sametime server and edit the file Lotus\Domino\data\domino\html\sametime\webattendstep_java.js and edit the first line:
var JavaInstallURL = "http://java.com
So change the "http://java.com
" to wherever you put the file
and users can go right to your package.
