Has anybody got any idea how this is achieved with eclipse. Alternatively is
the a nice simple GUI front-end for jdb which doesn't involve Eclipse?

Go to Preferences and make sure that you /are/ using Java 6.

Go to Properties for the project and make sure that /it/ is using Java 6, too.

I use RAD 7 (Rational Application Developer 7), which is based on Eclipse. Sometimes it complains that it cannot find java.lang.Object, which impedes the build a tad. Invariably it's due to project metadata being out of whack, thinking it's using a JRE that doesn't exist in the current IDE configuration being the most common that I've seen.

This happens sometimes when I import projects from an earlier version of the IDE.
