Yes, that is the same I would/want/must do, jai and java3d (and any
other extention) really need to be in the proper versions.
I'm not sure, but this could be a problem for different products using
java, since for example the uDig derivates take the jre if it is
inside the install folder, else they search for the JAVA_HOME, which
can be any installation on the system (usually jai-less) or none.
Not sure if it would be possible to place a version of java somewhere
and create links in the needed places.

The jre has to keep its structure in order to have the libs in the
right place. For windows this will mean a bin at same level as the lib
folder. I will have to try that out however. I will in any case have
to read through all the docu here to see how things were already done.

What would the purpose of geotools be in that case? A library ship?
Udig already ships with a geotools pack inside its libraries, even if
that is never the most advanced.
JGrass is basically an extention of uDig, but I'm not sure how this
later packaging should be done. Anyways, JGrass is pretty unstable
these days, so I agree with your proposal. I will have to talk to the
Refractions guys however, since they are the real lead of uDig, so
probably they would want to do this.
