java.lang.NullPointerException

-----BEGIN PGP SIGNED MESSAGE-----

Forgive me if this is the wrong mailing list for this, but it seemed the
most appropriate.

I've got a database up and running under PostgreSQL called kwn. When I
try to use the following Java code to connect to it:

try {
Class.forName("postgresql.Driver");
}
catch (Exception e) {
System.out.println(e);
}

postgresql.Connection conn = null;

try {
conn =
(postgresql.Connection)DriverManager.getConnection("jdbc:postgresql:kwn");
}
catch (Exception e) {
System.out.println(e);
e.printStackTrace();
}

I get the following stack trace from the second try block:

java.lang.NullPointerException:
java.lang.NullPointerException:
at java.lang.String.<init>(String.java)
at postgresql.Connection.<init>(Connection.java:71)
at postgresql.Driver.connect(Driver.java:87)
at java.sql.DriverManager.getConnection(DriverManager.java:91)
at java.sql.DriverManager.getConnection(DriverManager.java:149)
at CookBook.<init>(CookBook.java:165)
at CookBook.main(CookBook.java:335)

==============================================================================

The program was compiled with the command line:

javac -d . -classpath /usr/share/java/postgresql.jar:/usr/lib/jdk-1.1.3/classes.zip:. test.java

and my CLASSPATH env variable is:
/usr/lib/jdk-1.1.3/lib/classes.zip:/usr/share/java/postgresql.jar:.

As far as I can tell, the Class.forName() call doesn't throw any
exceptions.

Ideas, hints or suggestions greatly appreciated.

Kevin
