Get method calls of IMethod through eclipse CallHierarchy

Question

I am looking to get IMethod, IType or IJavaElement in which a IMethod is being called. I explored org.eclipse.jdt.internal.corext.callhierarchy.CallHierarchy. I have written this code but its not giving me anything in wrapper or in location. Please guide me.

public void getMethodCallers(IMethod[] methods){

CallHierarchy hierarchy = new CallHierarchy();
IJavaSearchScope searchScope= SearchEngine.createWorkspaceScope();
hierarchy.setSearchScope(searchScope);
CallLocation location = hierarchy.getCallLocation(method[0])
MethodWrapper [] wrapper = hierarchy.getCalleeRoots(methods);



}

This post describes in detail how to achieve this: Java: Find all callers of a method – get all methods that call a particular method
