Getting the Java Version I want in a SunOS account

Question

I have an account on a Unix server. I can't get it to point to the version of Java I want when I am in BASH.

The version of Unix is:

SunOS 5.10 Generic January 2005

This is what I have in my .profile:

#====================================================================
#   set the environment
#====================================================================

ANT_HOME=/apps1/apache-ant-1.8.4
export ANT_HOME

#  $PATH:/user1/acme21 needs to be included to make anything work
PATH=.:/usr/jdk/instances/jdk1.6.0_24:$ANT_HOME/bin:$PATH:/user1/acme21
export PATH

JAVA_HOME=/usr/jdk/instances/jdk1.6.0_24
export JAVA_HOME

CLASSPATH=.:/user1/sterus01/TestProgramsLib/mail.jar:/user1/sterus01/TestProgramsLib/activation.jar:/user1/sterus01/TestProgramsLib/log4j-1.2.16.jar:/user1/sterus01/TestProgramsLib/mail.jar:ojdbc14.jar
export CLASSPATH

env | grep DIS

# Use the bash shell, get many conveniences
bash

When I run echo $JAVA_HOME and echo $PATH I get

bash-3.00$ echo $JAVA_HOME
/usr/jdk/instances/jdk1.6.0_24
bash-3.00$

and

bash-3.00$ echo $PATH
.:/usr/jdk/instances/jdk1.6.0_24:/apps1/apache-ant-1.8.4/bin:/usr/bin:/usr/local/bin:/usr/ccs/bin:/usr/bin:/usr/sbin:/etc:/usr/ucb:/usr/local/sudo:/usr/local/sbin:/user1/acme21
bash-3.00$

Yet "which javac" reveals:

bash-3.00$ which javac
/usr/bin/javac
bash-3.00$

and "which java" reveals:

bash-3.00$ which java
/usr/bin/java
bash-3.00$

Is there anything I can do to get it to point to the Java version I specified in my .profile file?

Thanks in advance Happy Holidays Steve

I do not agree with my question being closed and voted down. I do not agree because I think getting the version of Java I want set up in a Unix account is about programming and is about software development. That is what I was trying to do when I ran into the problem that led to me creating the post. No disrespect. I value the moderation at stackoverflow. It is nice to ask a question without getting slammed, like on Usenet. — Steve, Apr 18 '13 at 18:29

Are you sure your java and javac executables are in /usr/jdk/instances/jdk1.6.0_24 ? Perhaps they are in /usr/jdk/instances/jdk1.6.0_24/bin/.

I suspect this:

PATH=.:/usr/jdk/instances/jdk1.6.0_24

isn't right, and you need instead

PATH=.:/usr/jdk/instances/jdk1.6.0_24/bin

to pick up the binary directory within that Java installation.

p.s. I wouldn't put the current directory (.) in your PATH. Otherwise someone can substitute a trojan-like program (e.g. a substitute for ls) in a directory. You'll pick that up when you cd into the containing directory and type ls (there's an entertaining story relating to this in the Unix Power Tools book)

That was it! Thanks. Thaks for the tip about removing the current directory from the path as well. – Steve Dec 21 '12 at 15:36
