As shankar_r mentioned, post the object browser view of the component that you are attempting to interact with and the hierarchal tree of ancestor objects leading up to it. That's the only way we can help you remap.
As noted above, the problem is probably not with the JCCalendarComponent itself but with one of the parent objects in your Alias tree. So, do the following to trouble shoot:
1) Get the component on screen so that it is visible in the object browser
2) In NameMapping, start with one of the parent objects of your component at the highest level of the tree, right click on it, and select "Show in object browser". If it works, that component is fine and go down to the next one. if it doesn't work, you've found your problem component.
3) Go back to your object browser and the problem component. Make note of properties that will uniquely identify it
4) Go back to name mapping, right click your problem component and select "Edit".
5) Make the necessary edits.
