Jar file has no source attachment

I've created a custom B2B application using the step-by-step guide, but am having trouble viewing the Java code within the SAP delivered classes. For example, when I try to look up the code within the ShowProductDetailAction.class, I get the following message:

The jar file sap.comcrmisaisacoredefault.jar has no source attachment.
