java.lang.ExceptionInInitializerError at driver load attempt.

This short Java Class:

import java.sql.*;

public class TestIt
{
static public void main (String args[])
{
try {
// Load the driver here ...
Class.forName ("org.postgresql.Driver");
}
catch (Exception e) {
System.out.println ("Yep, got an exception.");
e.printStackTrace();
return;
}
}
}

give this Java stack trace (at the Class.forName call):

java.lang.ExceptionInInitializerError: [exception was
kaffe.util.NotImplemented: java.lang.Runtime.addShutdownHook()]
at java.lang.Class.forName(Class.java:native)

Any idea what is going on here? The postmaster was started with pg_ctl start
-l logfile -o "-i".

I have the Java J2SE (Java 2) jdk 1.3.1_02 installed in /usr/java.
I am using the RedHat 7.2 supplied precompiled driver which is installed in
the /usr/share/pgsql/jdbc7.1-1.2.jar file.

My system is a AMD k6-2 550MHz.

Has anyone ever seen this error before?

Thanks.

Hello,

Can you please check which javac you're using? You can check this with 'which javac'. This will probably say /usr/bin/javac which is a part of the kaffe rpm in redhat 7.2. Kaffe is an open source implementation of a java virtual machine and class libraries (http://www.kaffe.org) and is't completely finished yet. You can remove this kaffe package with 'rpm -e kaffe' if you only want to use the sun jdk or you can use the full path to the javac of the sun jdk or maybe you can change the path to /usr/java/bin/:${PATH}.

Kind regards,
Dries

Thank you Dries. Yes, I was using the /usr/bin/java and /usr/bin/javac. I
didn't know I even had such in my /usr/bin directory. After using the
"correct" /usr/java/.../bin/java and javac everything works fine. I guess I
had better get my /usr/java/bin in front of my /usr/bin in the PATH env
variable. That explains why we were seeing the references to kaffe in the
stack trace.

Once again, thanks much.
