To make sure that Java is in the path

1. Log in to the system as SuperUser.
2. Type the following command:
   
   java -version
   
   This should return something similar to the following:
   
   java version "1.4.2"
   Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
   Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)
   
3. To determine where the Java binary lies in the system, type the following command:
   
   which java
    
4. If the location is not /usr/bin/java, add a symbolic link to that location, as in the following command:
   
   ln -s /usr/java/j2sdk1.4.2/jre/bin/java /usr/bin/java
