Jambi ships as a single Java library, or JAR (Java Archive) file, plus a handful of tools, including an interface layout and design tool, and an Eclipse plug-in. Trolltech uses its vaunted Qt C++ library as the GUI engine and puts Java wrappers around it. This approach uses the JNI (Java Native Interface) to call the necessary functions from Java. More here.

In Java you already have classes for network/sql/xml/file/etc access in the standard class library so a lot of Qt is not strictly necessary.
This is often missed by people who refer to Qt as "GUI Toolkit".
Qt is to C++ what the Java Classlibrary is to Java.
So obviously on Java, where it basically is just a "GUI Toolkit", there is a lot less need for it.
Interestingly, dispite only a small portion of Qt being of additional value for a Java developer, it is still considered for just its GUI portion.

Yeah it all depends on whether the classes are worth the money. As a C++ developer, Qt is easily worth the money. It is so far above any other C++ toolkit out there that I believe I get my money back in gained productivity very quickly.

Trolltech seems to realize this and charges significantly less for Jambi than the C++ version of Qt ($1780-$3560 vs $3300-$6600).
