Answer 1

The latest version of XQDT requires the dynamic languages toolkit [3.0.0, 4.0.0). In other words, the DLTK version must be >= 3.0.0 and < 4.0.0. If you're using Eclipse Juno, you'll need to download the DLTK from the Indigo update site (http://download.eclipse.org/releases/indigo), not the Juno update site. The XQDT plug-in doesn't like the fact that the version number of the DLTK from the Juno update site is > 4.0.0.
