hop of those help? No, the help system you point to is an eclipse plugin based system, useful with RCP programs. See http://wiki.eclipse.org/RCP It will only run in the context of an RCP application. You might be able to write an RCP app that contains only help, launch it, and communicate with it through http from your java app, but it's not a simple integration ... and you still have to build your help documents so that org.eclipse.ui.help can see them.
help you fix your problem Try enabling Preferences > General > Workspace > Refresh using native hooks or polling. Depending on what OS you're using it will refresh more or less quickly. It's not exactly what you want but it might solve the problem. Another option that I haven't tried myself but that looks like it could be made to work is to use eclipse-remote-control to trigger an external command you have set up in Eclipse (Run > External Tools > External Tools Configurations...), if you create a new "Program" configuration there you can in the "Refresh" tab set Eclipse to refresh the workspace when that external tool config is executed.
