Java Database Connectivity (JDBC)

Hi,

I am totally not familiar with JDBC. I hope you guys can help me to figure out if my JDBC is installed properly.

I have installed a Oracle Client 10g Rel 1 (10.1.0.3.0), and i have the following files under $ORACLE_HOME/jdbc
================================================================
classes12dms.jar* classes12.zip* ocrs12.jar* ojdbc14dms.jar* ojdbc14.jar*
classes12.jar* nls_charset12.jar* ojdbc14dms_g.jar* ojdbc14_g.jar* orai18n.jar*
================================================================

jdbc/lib> echo $JAVA_HOME
/usr/lib/jvm/java
jdbc/lib> echo $CLASSPATH
/sww/tools/oracle/product/10.1.0/jdbc/lib/ojdbc14.jar:/sww/tools/oracle/product/10.1.0/jdbc/lib/orai18n.jar

I have this code (i got it from oracle doc):
======================================================
import java.sql.*;
import oracle.jdbc.*;
import oracle.jdbc.pool.OracleDataSource;

class JDBCVersion
{
public static void main (String args[]) throws SQLException
{
OracleDataSource ods = new OracleDataSource();
ods.setURL("jdbc:oracle:thin:hr/hr@myhost:1521:lasdev");
Connection conn = ods.getConnection();

// Create Oracle DatabaseMetaData object
DatabaseMetaData meta = conn.getMetaData();

// gets driver info:
System.out.println("JDBC driver version is " + meta.getDriverVersion());
}
}
================================================================

Compiling
========================
/home/ysusanto> javac JDBCVersion.java
/home/ysusanto> java JDBCVersion
Exception in thread "main" java.lang.NoClassDefFoundError: JDBCVersion
=========================

Can you enlighten me what this error means and how to solve it?
I am running this on SUSE9

Thanks before for any response.
