Tracker in websphere portal 6

[viswam konkepudi]

Hi,

While migrating from web sphere portal 5 to 6

I have a scenario like this

RunData _runData = RunData.from(request);
Composition composition = (Composition)_runData.getAttribute("com.ibm.wps.composition");
if(composition == null) {
composition = Tracker.getRootComposition(_runData);
}
String title = LocaleHelper.getTitle((com.ibm.portal.Localized)composition, request);


But in portal 6 there is no Tracker.getRootComposition(_runData)

So how can achieve this.

Thanks In Advace
