Programação Java
#1

Dae pessoal blz … bom seguinte … gostaria d saber como conectar em um banco ODBC remotamente usando applet …

import java.applet.Applet;
import java.awt.Button;
import java.awt.Label;
import java.awt.TextArea;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class pricipal extends Applet implements ActionListener {

Button b = new Button("Iniciar");
Label prct = new Label("0.0 %");
Label contag = new Label ("...");
TextArea ta = new TextArea(5,50);
String caminho = "jdbc:odbc:kstudio";
static final String driver_class = "sun.jdbc.odbc.JdbcOdbcDriver";
int total;

public void actionPerformed(ActionEvent ae){
	
	if (ae.getSource() == b){
		
		CheckUrl checkUrl = new CheckUrl();
		
		


	    try {
	    
	    	Class.forName(driver_class);
	    
	    	Connection con = DriverManager.getConnection(caminho,"","");
	    	Statement d =  con.createStatement();
			Statement d2 =  con.createStatement();
			Statement d3 =  con.createStatement();
			String query = "select url.url from url ";
			
			
			String query2 = "select count(*) from url" ;
			ResultSet rr = d.executeQuery(query);
			
			ResultSet rcount = d3.executeQuery(query2);
			
			rcount.next();
			total = rcount.getInt(1);
		
			double atual;					
			int i = 0;
			while (rr.next()) {
				System.out.println(i);
				checkUrl.status = false;
				String aux = rr.getString(1);
				
				checkUrl.url = aux;
				checkUrl.verificaUrl();
				String update;
				if (checkUrl.status == true){
					update = "UPDATE url SET url.status = 'S' WHERE url.url = '" + aux +"'";	
					}
					else
						{
						update = "UPDATE url SET url.status = 'N' WHERE url.url = '" + aux +"'";	
						}
				d2.executeUpdate(update);		 		
				i++;
				ta.append(checkUrl.linha + "\n");
				
				
				
				atual = (i * 100)  / 4953 ;
				
				String strValue = String.valueOf(atual) + " %"; 
			    prct.setText(strValue);
			    contag.setText(String.valueOf(i) + " / " + String.valueOf(total));							
				}
			checkUrl = null;
			d.close();
			con.close();
			
		} catch (SQLException e2) {
			// TODO Auto-generated catch block
			e2.printStackTrace();
		
		} catch (ClassNotFoundException e) {
			ta.append("ClassException: " + e.getMessage());
			e.printStackTrace();
		
		}

} }

public void init() {
		setLayout(null);
		setSize(550,200);
		ta.setBounds(10,10,510,100);
		b.setBounds(10,120,75,25);
		prct.setBounds(400,120,75,25);
		contag.setBounds(400,150,75,25);
		b.setVisible(true);
		ta.setVisible(true);
		prct.setVisible(true);
		add(b);
		add(ta);
		add(contag);
		add(prct);

		
	    ta.append("entro1");
	    b.addActionListener(this);
	
	    
}

}

parece q borta no class.ForName … desd ja agradeço a todos …
