java: gij

i got this when i tried running java on my box

# java
Usage: gij [OPTION] ... CLASS [ARGS] ...
          to invoke CLASS.main, or
       gij -jar [OPTION] ... JARFILE [ARGS] ...
          to execute a jar file
Try `gij --help' for more information.

apparently, my box points to gij instead of sun's java.
to point the java shell command to the other java...

you can edit the java command link:
1. locate the java command used by shell
# which java
2. remove the symbolic link that points to gij
# rm /usr/bin/java
3. create a new symbolic link pointing to the java to be used
# ln -s <path to my java> /usr/bin/java

or just set JAVA_HOME variable in the .bash_profile file:
JAVA_HOME=<path to my java>

which ever way you want to go
