Simple DB Connection using DSN

Question

Hi,
I compiled this code in Unix and try to run it, but I'm getting error "java.sql.SQLException: No Suitable driver" although i've already defined my dsn in ODBC connections ("system dsn"). What's wrong?
import javax.swing.JOptionPane;
import java.sql.*;
/home/users/almong/.J[GARY]>more Connect.java
import javax.swing.JOptionPane;
import java.sql.*;
public class Connect{
public static void main(String args[])
String dataSourceName="XYZDummy";
String dbURL="jdbc:odbc" + dataSourceName;
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection(dbURL,"","");
Statement s = con.createStatement();
s.execute("select * from employee_v where staff_num='5377' ");
ResultSet rs = s.getResultSet();
if (rs != null)
while(rs.next())
JOptionPane.showMessageDialog(null,"Employee:" + rs.getString(
2),"TEST ONLY",JOptionPane.INFORMATION_MESSAGE);
s.close();
con.close();
catch(Exception err){
System.out.println("ERROR:" + err);
}

There are a couple of reasons for the No Suitable Driver error (see the following thread for more detail: http://forum.java.sun.com/thread.jspa?forumID=48&threadID=656329). In your case it happens to be a malformed JDBC URL that is the problem. A JDBC URL is comprised of three parts separated by colons. You have the following code:
String dbURL="jdbc:odbc" + dataSourceName;You are missing a colon between the sub-protocol name (odbc) and the datasource name. Your code should read:
String dbURL="jdbc:odbc:" + dataSourceName;
