jde-javadoc-make question

I'm sure this is a configuration option.  I didn't see anything in the 
list, but when I generate my JavaDoc, I don't get the links for the JDK 
classes.  Can I assume that because the source is located in the ZIP file? 
 Perhaps, I need to unzip the src.zip?  jde-help-show works, but that's 
not tied in with the JavaDoc stuff?

Constructing Javadoc information...

c:\j2sdk1.4.2_13\src.zip(java/awt/BorderLayout.java):107: class 
BorderLayout is public, should be declared in a file named 
BorderLayout.java

(source unavailable)

Thanks,
Jeff
