I'm sure this isn't possible but figured I'd check -- Using Adobe, is there a way to open a PDF from a webpage. The PDF would then be viewed and marked up if necessary.

Eclipse recognises these as valid because I can hit ctrl-space and they pop-up. I also get Javadoc for javax classes. But there is no Javadoc for these a...
I have an abstract superclass that has JPA annotations on it mapping some of its fields. The class itself has the @MappedSuperclass annotation. Can I specialize/add or change just one element of an inherited annotation without re-specifying the entire annotation? ...
