Ho bisogno di connettere DB2 con Java. Gentilmente aiutami a connetterti allo DB2 con java in ECLIPSE. Sarebbe di grande aiuto se si potesse guidarmi passo dopo passo prega fatemi sapere come aggiungere classpath in Eclipse frammento di codice:Connetti DB2 con Java
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;
}
}
}
Sulla esecuzione del codice ho ottenuto le seguenti eccezioni:
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 connection.main(connection.java:11)
Il mio utilizza com.ibm.db2.jcc.DB2Driver ... non so quale sia la differenza – ESP
@ESP Aggiunta la mia risposta alla tua domanda. –
qualcuno potrebbe aggiungere un collegamento per scaricare e installare il driver? –
