Do I need install some java ext libray. my JRE is jdk1.5.(jre-1_5_0-windows-i586.exe). and I can see the jai_core.jar file in jre\lib\exe directory.

Then I modified my own eclipse3.0m2 jre to the installer package's jre subdirectory. I think the install packge jre should contain the JAI library. right? then I run the udig in Eclipse . but it still  prompt the warn dialog: "Java Advanced Imaging is not installed.Map view...................." .

I think we need to check your "Run" again ... step 1 made sure you set
the following:

-Dosgi.parentClassloader=ext

This is needed or JAI will not befound by the plugin classloader(s).

Do you have this one? You may also want to confirm that your "Installed
JRE" is indeed pointing at the one from udig 0.6.
1) Window > Preferences > Intalled JREs
2) Select your JRE and press Edit
3) Ensure the following JAI jars are listed under Use default system
librarie:
jai_codec.jar
jai_core.jar
jai_imageio.jar
mlibwrapper_jai.jar

If they are not in the list then we need to find you a different JAI to
run against.
