Java,Oracle on Solaris need Help Uragent

Hi,
I have installed JDK1.2.2 and oracle 8.1.6 on Solaris 2.8(Unix).
I am able to compile and execute simple java programs. Now Iam trying to run jdbc programs.
In order to do that I downloaded Oracle driver for Solaris and added classpath with classes12.zip. Now my Jdbc programs as well as simple programs are compiling successfully but not executing. Any help to soleve this problem is appreciated.
gdgd% echo $CLASSPATH
/emc/bsugeera/classes12.zip

gdgd% javac Employee.java
gdgd% java Employee
Exception in thread "main" java.lang.NoClassDefFoundError: Employee
gdgd%

Sorce code for Employee.javaclass Employee
import java.sql.*;
class Employee
{
public static void main (String args [])
throws SQLException
{

DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());

Connection conn =
DriverManager.getConnection ("jdbc

racle

ci8:@servername.port.dbname", "scott", "tiger");

Statement stmt = conn.createStatement ();

ResultSet rset = stmt.executeQuery ("select ENAME from EMP");
while (rset.next ())
System.out.println (rset.getString (1));

rset.close();

stmt.close();
conn.close();
}
}

Thanks in Advance.

Hello,
The NoClassDefFoundError is usually thrown if the Java Virtual Machine or a classloader tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.
The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found
