Eclipse WTP - Apache Derby [message #170078]

I'm trying to deploy a web service that connects to a Derby database using
Eclipse WTP. Running my code as a standalone app works fine. As soon as
I deploy it as a web service it can no longer find the database driver to
make a connection.

Here's my connection code from the service:

String dbUrl = System.getProperty("APDLdb.url",
"jdbc:derby:APDLdb");
String dbDriver System.getProperty("APDLdb.driver",
"org.apache.derby.jdbc.EmbeddedDriver");
String dbUser = System.getProperty("APDLdb.user", "apdl");
String dbPassword = System.getProperty("APDLdb.password", "apdl");
Connection conn = null;

try {
Class.forName(dbDriver).newInstance();
conn = DriverManager.getConnection(dbUrl, dbUser, dbPassword);

} catch (Exception e) {
e.printStackTrace();
}

Here's the error:

java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver

Seems like it should be simple enough to fix...I've used the Derby plugin
to add the Derby jar's to the projects, but still no luck. Is there
something I'm missing on configuring a dynamic web project?

I am a newbie and have spent quite a bit of time trying to figure this one
out on my own...even bought the Pro Eclipse JST book...followed their
examples exactly without any luck either.

Thanks in advance.
