Hi,

This is the output of the commands suggested:

root@myserver # which java
/usr/bin/java

root@myserver # java -version
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 2.2)
IBM J9SE VM (build 2.2, J2RE 1.4.2 IBM J9 2.2 Linux amd64-64
j9xa64142-20061124 (JIT enabled)
J9VM - 20061121_1035_LHdSMr
JIT  - r7_level20061020_1803)

My path:

root@myserver # echo $PATH
/sbin:/usr/sbin:/usr/local/sbin:/opt/gnome/sbin:/root/bin:/usr/local/bin:/u=
sr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin:/opt/kde3/bin:/usr/lib=
64/jvm/jre/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/opt/jruby/bin:/usr/local=
/bin:/usr/local/sbin:/suptools/bin:.

Thank you
