First, try
locate -r 'bin/java$'
I see this:
[...]$ locate -r 'bin/java$'
/usr/local/bin/java
/usr/local/ImageJ/ImageJ/jre/bin/java
/usr/java/j2re1.4.2/bin/java
/usr/java/j2re1.4.1_02/bin/java
/usr/java/j2sdk1.4.1_02/bin/java
/usr/java/j2sdk1.4.1_02/jre/bin/java
Try this command:
ls -l /philtr/j2sdk_nb/j2sdk1.4.2./jre/bin/
I suspect that gives an error message.
I don't think the period after 1.4.2. should be there, because I
happen to know that people at Sun would never make a directory
name ending in a period. It just isn't done, even though there
is no rule against it.
So try this:
ls -l /philtr/j2sdk_nb/j2sdk1.4.2/jre/bin/java
You should see something like
-rwxr-xr-x 1 philtr philtr 24564 Jun 20 05:04 java
Once you have found your java executable, fix PATH. Try
PATH=/philtr/j2sdk_nb/j2sdk1.4.2/jre/bin/:$PATH
and then
java -version
This works until you exit the shell where you fixed PATH.
So either change your .bash_profile, or put the PATH into
the script.

Not something to do. The _ is just another letter in the variable name.
JAVA_IMPL=`java -version 2>&1 | head -1 | cut -f1 -d' '`
That line means the following:
Set the variable JAVA_IMPL to the string following the equal,
after expansion.
The stuff after the equal means: execute the pipeline and
replace the backquotes and all inside with the output of the
pipeline. The pipeline executes 'java -version', i.e. it
runs java with the option asking it to print the version.
It assigns stderr to the same file as stdout (2>&1), and
pipes the output into the head -1 command. That
discards all but the first line of the output. The
single line goes into cut -f1 -d' ', which takes the first
field delimited by blanks.
So JAVA_IMPL is set to be the first word of the first line
output by java -version. In the case of Sun's 1.4.2, that
is "java".
But I don't see where JAVA_IMPL is used. It isn't exported,
and it isn't reference in this script.

Hmm. Should have read all the way down. You found the right
bin/java above, but made a typo in your PATH= command.
Actually, I find that the two files are identical:
cmp /usr/java/j2sdk1.4.1_02/bin/java \
/usr/java/j2sdk1.4.1_02/jre/bin/java
produces no output.

This should have worked.
Rumor has it that 1.4.1_02 works better with freenet. I have
both, but use 1.4.1_02.
