Question Updating environment variables
ok, this definitely falls in the n00b category... I'm trying to upgrade Java on my server and just need to update the PATH, CLASSPATH, and JAVA_HOME environment variables.

This is what they currently are:
PATH=/usr/local/jdk1.5.0_15//bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/java/bin:/usr/local/ant/bin:/root/bin
JAVA_HOME=/usr/local/jdk1.5.0_15/
CLASSPATH=/usr/local/jdk1.5.0_15//jre/lib

This is my java install directories under /usr/local:
4 drwxr-xr-x 9 root root 4096 Sep 19 2008 jdk1.5.0_15
4 drwxr-xr-x 10 root root 4096 Sep 23 2008 jdk1.6.0_07
0 lrwxrwxrwx 1 root root 11 Sep 23 2008 java -> jdk1.6.0_07

And this is the java that is being used:
[root@dev local]# which java
/usr/local/jdk1.5.0_15/bin/java

I looked at my /etc/bashrc and it is calling /etc/profile.d/java.sh, which looks like this:
export JAVA_HOME=/usr/local/java
export ANT_HOME=/usr/local/ant
export PATH=$PATH:$JAVA_HOME/bin:$ANT_HOME/bin

What's confusing me is that I can see that the java.sh is indeed running but things aren't working out properly.
1) I can see the java.sh appends the last 2 entries of the PATH shown above. But the first entry in the path goes to the jdk1.5 with a double //bin.
2) JAVA_HOME does not point to /usr/local/java but to /usr/local/jdk1.5.0_15/

Any ideas how to figure this out?

Thanks!

AIRPORT2-IPINSPECTOR(1) 				      General Commands Manual					   AIRPORT2-IPINSPECTOR(1)

NAME

       airport2-ipinspector - WAN monitoring utility for the Apple AirPort Extreme Base Station ("Snow")

SYNOPSIS

       airport2-ipinspector

DESCRIPTION

       airport2-ipinspector  monitors the WAN interface of the base station and sends an email notification whenever the external (WAN) IP address
       of the base station changes.

OPTIONS

       airport2-ipinspector accepts no command-line options. airport2-ipinspector is a wrapper script around the IPInspector.jar jar file  located
       in /usr/share/java/airport-utils.

       You  can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The full path to the Java Virtual Machine to use.  By  default,  the  wrapper  uses  JAVACMD;  if  it  is  not  set,  it	looks  for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
