BTDT. This problem was fixed in a later release of JDBC.
Explanation is below.

Hi,
Actually, It is a HP JDBC driver "BUG". I think it will be solve in the next
release. To pass this trouble, try :
....
System.setProperty("jdbc.drivers", drivers); // or Class.forName(....)
DriverManager.setLogStream( System.out); // Bcause PointerException.
connection = DriverManager.getConnection(url, username, password);
....
setLogStream (JDK 1.1.X) is a depreciated method ( replaced by setLogWriter
JDK 1.2.x and JDBC 2). The default logWritter is null. For debug or just
trace, you can set the logStream to any PrintStream you want: standard
output, file, printer ...
With the new method setLogWriter you can set the logWriter to a PrintWriter.
