Bug 21583 Generate Javadoc won't link prereqed projects
In the export wizard for generating javadoc, there is no easy way to link the javadoc from a prereqed project. The wizard has a screen for linking in javadoc from libraries included in the classpath, but projects in the classpath do not show up. I got a temporary workaround from the news group. Just add a "-link URL_TO_OTHER_PROJECT_JAVADOC" in the javadoc options page, but there should be an easier way to do this.
