How do I add a Lifeline for a Sun Java class?

[tomkalafut]

I drag and drop my classes from the Class Model into my Sequence Diagram (as simple links) to add a Lifeline.  How would I do the same for say a Sun Java class like java.security.KeyStore, so that Keystore's methods pop up in the drop down Message text box in the Message Properties dialog?

Do I need to Import (Binary Module) the entire rt.jar file into my Class Model, or is there a simpler way?  Should I Import each Sun Java source file into my Class Model as needed?

Yes, you need to import any Java classes you want to include into your model.  EA doesn't include a built in library of classes available for each of the various frameworks (and framework versions) of the languages supported.
