jdbc7.0-1.2.jar problems

Hi.

I have some problems with PostgreSQL 7.0.2 and JBuilder 4 Foundation and
JavaServer Pages.
My development platform is Red Hat 7.0 and JDK 1.3.

When I try to compile my JavaBean (DatabaseHandler) it freeze's when it
reach the no. 2
codeline (prints "1" - and thats it.):

1.) System.out.println("1");
2.) conn =
DriverManager.getConnection("jdbc:postgresql:testdatabase","user","1234");

3.) System.out.println("2");

Where "user" = linux database admin, and "1234" = linux password.

JBuilder never finishes the compile sequence....and when I use the
JavaBean with JavaServer
Pages I get a java.lang.NullPointerException.

I start the PostgreSQL database server with this command:

/usr/bin/postmaster -D -i /home/user/databaseserver

I have added the following line to /etc/profile:
CLASSPATH=$CLASSPATH:/usr/lib/pgsql/jdbc7.0-1.2.jar, and I have also
added: /usr/lib/pgsql/jdbc7.0-1.2.jar to PATH in /etc/profile.

In JBuilder 4 Foundation the /usr/lib/pgsql/jdbc7.0-1.2.jar have been
added to the Class tab in
the Configure JDKs dialog box.

Some of my friends told me to unpack the jdbc7.0-1.2.jar file and place
the org package inside tomcat/webapps/root/classes - but I have not
tried that yet.

But anyway - it would be nice to use the postgresql database server from
both JBuilder 4 Foundation and JavaServer Pages (Tomcat).

Thanks.
