Thank you, I have modified the code but doesn't even work...
I try this...
public static void CBD() throws IOException,
java.sql.SQLException,ClassNotFoundException
     String url= "jdbc: AvenirDriver: //192.168.0.123:
1433/BKCOFF";
     Class.forName ("net.avenir.jdbc2.Driver");
     Connection ctn          = DriverManager.getConnection
(url,"sa","");
     Statement stmt          = ctn.createStatement();
     boolean moreResult     = stmt.execute("select * from
TDB");
     int updateCount          = stmt.getUpdateCount();
     ResultSet rst          = null;
     rst = stmt.getResultSet();
     while(rst.next())
          System.out.println(rst.getObject(1));
void button2_actionPerformed(ActionEvent e){
int i = 0;
CBD(); //<--Error #: 360 : unreported exception:
java.lang.ClassNotFoundException; must be caught or declared to be
thrown at line 201, column 8
