  Hi folks,
  Just wondering if I am reading the error correctly.

Hub>>java sample
Exception caught.
java.lang.ClassNotFoundException: org.postgresql.Driver
java.lang.ClassNotFoundException: org.postgresql.Driver
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:191)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:290)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:282)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName(Class.java:124)
        at sample.<init>(sample.java:10)
        at sample.main(sample.java:38)

I am assumung that this means the it isn't finding org.postgresql.Driver
in the postgresql.jar file.

Am I wrong?

No, I think you're right.  My guess is that it isn't finding the jar file.
Add the path to your jarfile to your CLASSPATH environment variable, and try
again.

    good luck,

The jar file is located in:
/usr/local/java_pkgs/jdk1.2.2/jre/lib/ext/

My classpath is set to:
export CLASSPATH=/usr/local/java_pkgs/jdk1.2.2/jre/lib/ext/postgresql.jar:.

Is there any errors there?

Thanks Charlie,
  I don't seem to have this file anywhere on my filesystem, but that
could be it.  Does anyone know if this file is needed?
