You should make sure you have the sbt.web project on your server. It sounds like the ForumsService dojo file isn't found.
Also make sure that your managed-beans.xml file is configured, and set properly to point to your connections server.
Here is a snippet which shows the path invocation for ForumService. You can see many more examples in the GitHub Project and reference the wiki which describes your first JS App http://www-10.lotus.com/ldd/appdevwiki.nsf/xpDocViewer.xsp?lookupName=SDK+docs#action=openDocument&res_title=Adding_the_SDK_to_your_web_application_SDK1.0&content=sdkcontent
require(["sbt/connections/ForumService", "sbt/dom", "sbt/json"],
function(ForumService, dom, json) {
var forumService = new ForumService();
var forumUuid = "%{name=ForumService.forumUuid}";
var promise = forumService.getForum(forumUuid);
promise.then(
function(forum) {
dom.setText("json", json.jsonBeanStringify(forum));
},
function(error) {
dom.setText("json", json.jsonBeanStringify(error));
}
);
}
);
