Tags: ,



I need to connect DB2 with Java. Kindly help me to connect DB2 with java in ECLIPSE. It would be of great help if you could guide me step by step Please let me know how to add classpath in eclipse code snippet:

import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;

public class connection {
    public static void main(String[] argv) {
        try {
            Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
        }
        catch (ClassNotFoundException e) {
            System.out.println("Please include Classpath  Where your DB2 Driver is located");
            e.printStackTrace();
            return;
        }
        System.out.println("DB2 driver is loaded successfully");
        Connection conn = null;
        PreparedStatement pstmt = null;
        ResultSet rset=null;
        boolean found=false;
        try {
            conn = DriverManager.getConnection("jdbc:db2:sabarish","db2admin","Murugasaranam");
            if (conn != null)
            {
                System.out.println("DB2 Database Connected");
            }
            else
            {
                System.out.println("Db2 connection Failed ");
            }
            pstmt=conn.prepareStatement("Select * from bo");
            rset=pstmt.executeQuery();
            if(rset!=null)
            {

                while(rset.next())
                {
                    found=true;
                    System.out.println("Class Code: "+rset.getString("clcode"));
                    System.out.println("Name: "+rset.getString("name"));
                }
            }
            if (found ==false)
            {
                System.out.println("No Information Found");
            }
        } catch (SQLException e) {
            System.out.println("DB2 Database connection Failed");
            e.printStackTrace();
            return;
        }
    }

}

On running the code I got the following exceptions:

 java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver
 at java.net.URLClassLoader$1.run(Unknown Source)
 at java.security.AccessController.doPrivileged(Native Method)

 at java.lang.ClassLoader.loadClass(Unknown Source)
 at java.lang.Class.forName0(Native Method)
 at java.lang.Class.forName(Unknown Source)
 at connection.main(connection.java:11)

Answer

You need to correct the package name.

Class.forName("com.ibm.db2.jdbc.app.DB2Driver");

To add .jar in your project => Project + Properties + Java Build Path + Select “Libraries” tab + Add External Jars…
