I am learning Java(JDBC)
This is the code:

import java.sql.*;
     
public class CreateCoffees {

     public static void main(String args[]) {
           
          String url = "jdbc:odbc:Northwind";
          Connection con;
          String createString;
          createString = "create table COFFEES " +
                                   "(COF_NAME varchar(32), " +
                                   "SUP_ID int, " +
                                   "PRICE float, " +
                                   "SALES int, " +
                                   "TOTAL int)";
          Statement stmt;
     
          try {
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

          } catch(java.lang.ClassNotFoundException e) {
               System.err.print("ClassNotFoundException: ");
               System.err.println(e.getMessage());
          }

          try {
               con = DriverManager.getConnection(url,
                                              "sa", "");
     
               stmt = con.createStatement();                                  
                      stmt.executeUpdate(createString);
     
               stmt.close();
               con.close();
     
          } catch(SQLException ex) {
               System.err.println("SQLException: " + ex.getMessage());
          }
     }
}

This is the error:

Exception in thread "main" java.lang.NoClassDefFoundError: c:\javs\jdbc3\codeExa
mples\firstEdition\CreateCoffees

what causes this error?

I have setup the DSN Northwind already.
what is wrong with this line:

Class.forname(sun..........)?

How do I find out if this Drive class exited? I did install JDK1.3.1 on my winnt4 machine

Thanks

This error is as a result of your classpath not being ser to the location of the class CreateCoffees.....so include the location of CreateCoffees.class in your classpath

Besides you mean Class.forName("sun.....") right?.....as you might know java methods are casesensitive and the argument is a String

do this:

c:> cd to your porject directory
c:project dir>c:\jdk1.3.1\bin\javac -classpath . project.java

now you will see the class file the javac just created.

c:project dir>c:\jdk1.3.1\bin\java -classpath . project(this is the class file)
