Re: [udig-devel] uDig 0.6 problems with JAI in Windows 2000

[Chris Holmes <cholmes@xxxxxxxxxxxxx>]

I had major problems with this back with 0.4, which is why I am waiting
for the windows installer.  If you are a java developer, with lots of
jre's and jdks, then udig does not do a good job of getting the right one
(imho, as I spent half a day on this, it's just not flexible, ignores your
JAVA_HOME when I think that's what it should use first, since it's
actually under the control of the programmer, instead of random registry
variables).  I think the suspicions about the JDk may be correct though,
if I remember right.  If you do the jdk install of the jai stuff then it
goes into the private jre, when udig uses the public one.  So I think you
need to download the installers that say they are for the jre, and install
a jre only.  I believe that finally got me working with it.
