No, there’s still no document that describes the configuration, but it’s rather simple. On the Window > Preferences > MyEclipse > Application Servers > JRun 4 preference page, just point it to the JRun directory and set the server name you’d like to start. You can even leave the server name blank to launch the default.
You’ll also need to be sure that the JRun 4 > JDK preference page is set to launch JRun with a full JDK, not just a JRE, just like the other servers. That’s about it.
