Hi Minh,

It seems like you have atleast two versions of java installed (the sun
version you downloaded and the jdkgcj version). And, your
environment variables are pointing to a nonstandard/old version of java

To fix this,  you need to update your PATH variable to point to the
Sun java install.  Typically, this is installed in /usr/share/bin or
/usr/bin/java.   Once you update your PATH variable to point to the
correct java version,  "java -version" will return:
  java version "1.4.0_01"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
  Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)

If you have difficulties, email me (off-list) and I'll try and help.

Also,  the brite-users list is archived at:
and linked from the contact page.

Good luck,
