title: Attaching javadoc to libraries
body: <p>as an example, I'd like to attach the javadoc to org.eclipse.swt
  As I've read in similar threads, I went to the build path, expanded the swt library node and tried to enter the url as the javadoc location:</p>
  
  <p><a href="http://help.eclipse.org/indigo/advanced/content.jsp?topic=/org.eclipse.platform.doc.isv/reference/api/index.html" rel="nofollow">http://help.eclipse.org/indigo/advanced/content.jsp?topic=/org.eclipse.platform.doc.isv/reference/api/index.html</a></p>
  
  <p>Trying to validate it however tells me that typical root files like package-list or index.html couldn't be found. Obviously pretty weird since the url ends with index.html. Am I doing something wrong?</p>
