ssl-explorer complains of no JAVA_HOME


Hello all,

I am trying to get ssl-explorer up and running so I can test it out an I am running into a problem. I am trying to install the servers on my Fedora Core 6 machine and it is giving me the following complaint:

JAVA_HOME points to a missing or invalid Java runtime,
please set JAVA_HOME environment variable or provide
-j <java-home> argument.

Even when I run it with the -j option it still gives me the same complaint.

Can anyone tell me how to set the JAVA_HOME Environment Variable?

I have tried specifying the following in my /etc/profile.d/java.sh:
export JAVA_HOME=/opt/jre1.5.0_11/bin

I have tried the following on the command line as root:
export JAVA_HOME=/opt/jre1.5.0_11/bin

nothing has worked for me.

Hi.

The JAVA_HOME variable should point to the Java install directory, so just chop the /bin off the end of the path:
Code:
export JAVA_HOME="/opt/jre1.5.0_11"

How can I tell if this worked? is there an echo command I can use that should tell me what the environment variable points to?

Of course (I should have known). - Thanks for that. It does show what I have that it is set.

[lem@linux ~]$ echo $JAVA_HOME
/opt/jre1.5.0_11

Unfortunately when I try to run it, I still get the same error.

[root@linux linux]# ./install-service
Detecting Java
JAVA_HOME points to a missing or invalid Java runtime,
please set JAVA_HOME environment variable or provide
-j <java-home> argument.

Anyone got any ideas of what I can do?

Obvious question:
Does /opt/jre1.5.0_11 actually contain a Java installation?

Also, what type of file is install-service ? Is it a shell script, or a binary? If it's a shell script, you could probably take a look inside it, and see how it determines whether or not the JAVA_HOME variable points to a Java install.

These are the lines which matter:
Code:
if [ -n "${JAVA_HOME}" ]
then if [ ! -d "${JAVA_HOME}" -o ! -f "${JAVA_HOME}/bin/java" ]
The first checks whether $JAVA_HOME is null.
The second checks first to see if $JAVA_HOME is a directory, then checks that $JAVA_HOME/bin/java exists.
One of these chacks is failing.

Could you run the following, and post the output:
Code:
echo $JAVA_HOME
ls /opt
ls -ld $JAVA_HOME
ls -l $JAVA_HOME/bin/java

Ah.

Your $JAVA_HOME still points to /opt/jre1.5.0_11/bin . It should point to /opt/jre1.5.0_11/

Through all this, I forgot about that file. I made the change and I was able to install the service:

[root@linux linux]# ./install-service
Detecting Java
Using /opt/jre1.5.0_11/
Detect OS redhat
Service installed

Thanks for all the help guys I really appreciate it.
