I mentioned Jump
in passing last week and a helpful reader pointed me to its successor,
uDig. uDig looks pretty
cool. It is written as an Eclipse RCP application, which is fun.
Read the
tutorial, some screenshots are there.

My correspondent (I’m not sure of the etiquette here so I opted to
keep him anonymous) also writes that this won’t work with Classpath
yet, as we don’t have Java3D; but he adds: “However, no one expects
that situation to last indefinitely and we are all looking forward to
escaping the java trap.” How nice to hear that.
