how can i view the eclipse documentation and help offline within the IDE. currently when i try to view any help topic, it tries to get connected to the net.
If your talking about the documentation in Help > Help Contents the help is generally served from your machine. However, Eclipse uses a local instance of Tomcat to serve the help so you might be seeing an alarm in your firewall software about opening a socket. You can adjust the port that the internal Eclipse help system runs on at Window > Preferences > Help > Help Server. When all the options are blank (as by default) it uses a random port on your machine for Tomcat to server the help docs.
Note, that doesn’t mean that it’s not possible to have part of the help docs served remotely, because it certainly is. Howevr, that’s not the “general” case with the bundled Eclipse help documentation.
