Subject: Derby database (newbie) 2006-11-18 - By Peter Bradley
Back
Good afternoon.
I've bought SAMS Teach Yourself J2EE in 21 days, but even though I've
downloaded the J2EE 1.4 package, it uses the Derby database rather than the
Pointbase database on which the book is based. Can anyone tell me how I can
convert the sample code supplied with the book to use Derby instead?
I have J2EE 1.4.03 and jdk 1.5.0.09 with netbeans 5.5.
The first exercise is to set up the database, and I tried changing:
// PointBase
private static final String driver = "com.pointbase.jdbc.jdbcUniversalDriver";
private static final String protocol =
"jdbc:pointbase:server://localhost/sun-appserv-samples,new";
private static final String user = "pbPublic";
private static final String password = "pbPublic";
To:
// Derby
private static final String driver = "org.apache.derby.jdbc.EmbeddedDriver";
private static final String protocol =
"jdbc:derby://localhost/sun-appserv-samples,new";
private static final String user = "app";
private static final String password = "app";
But with no luck.
The ant files that the book provides contain some references to Pointbase
that I don't really understand so I've left them alone.
I got the driver string from the Drivers list in the netbeans Projects window.
I've tried using the supplied source file in a new netbeans project, but
although it compiles just fine, it fails at runtime with the message:
java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver
Presumably that means the required library isn't on whatever classpath
netbeans is using - but I'm only guessing. It's a long time since I did any
Java programming, especially with netbeans.
Any suggestions as to how I should proceed will be gratefully received.
Thanks
Peter
