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!

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list. Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)). FILES
