Google Maps

aszarael · Janeiro 18, 2012, 7:38am

Bom dia Pessoal

estou tentando fazer uma consulta no google maps.
mais ao executar o metodo


public class GoogleMapsStatic {

    public void GeraVisualizacao(String endereco) throws Exception{

        String adresse;
	adresse = endereco;


//        getImage(urlEncode(endereco));
	JFrame frame = new JFrame();
	JPanel panel = new JPanel();              //  http://maps.googleapis.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false

        URL url = new URL("http://maps.googleapis.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false");
	BufferedImage image = ImageIO.read(url);

        JLabel label = new JLabel(new ImageIcon(image));
	panel.add(label);
	frame.add(panel);
	frame.pack();
	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	frame.setLocationRelativeTo(null);
	frame.setVisible(true);
    }
}

Acontece o seguinte erro

Carinha, aparentemente o que você está fazendo é para funcionar. Fiz algo similar para testes:

[code]import java.awt.Rectangle;
import java.awt.image.BufferedImage;
import java.awt.image.ColorModel;
import java.awt.image.Raster;
import java.awt.image.RenderedImage;
import java.awt.image.SampleModel;
import java.awt.image.WritableRaster;
import java.io.File;
import java.io.InputStream;
import java.net.URL;
import java.util.Vector;

import javax.imageio.ImageIO;

public class TesteGoogleMaps {

public static void main(String[] args) throws Throwable {
	URL url = new URL("http://maps.googleapis.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false");  
	BufferedImage image = ImageIO.read(url);
	

	ImageIO.write(image, "jpg", new File("out.jpg") );
}

}[/code]

Então, o que pode estar acontecendo é que a aplicação java não está conseguindo acessar a internet. Verifique se há algum firewall impedindo o acesso.

Entendi, pode ser o proxy da empresa ?

Se for tenho e só informar junto ?

abmpicoli · Janeiro 18, 2012, 4:53pm

Carinha, googley “java url proxy” e ele me veio com esse link:
http://docs.oracle.com/javase/6/docs/technotes/guides/net/proxies.html. Esse cara fala como configurar o proxy para uma conexão.
Dá pra fazer por System.property:

[code]System.setProperty(“http.proxyHost”, “webcache.mydomain.com”);
System.setPropery(“http.proxyPort”, “8080”);

// Next connection will be through proxy.
URL url = new URL(“http://java.sun.com/”);
InputStream in = url.openStream();

// Now, let’s ‘unset’ the proxy.
System.setProperty(“http.proxyHost”, null);

// From now on http connections will be done directly.[/code]

Fiz a seguinte alteração no meu codigo


        System.setProperty("http.proxySet", "true");
        System.setProperty("http.proxyHost", "192.200.9.7");
        System.setProperty("http.proxyPort", "3128");
        System.getProperties().put("http.proxyPort", "8080");  
        System.setProperty("http.proxyType", "4");
        String proxyUser = "ifariaj";
        String proxyPassword = "**";

Porem ainda está apresentando o seguinte erro :

Carinha, sem ir praí tá difícil, né? Só uma coisa, você tá setando duas coisas juntas aí, né? O proxyPort é setado como 3128 e como 8080… Mas, fiz outra coisa:

google “proxy” e “java.net.ConnectionException” e veio o seguinte link: http://stackoverflow.com/questions/62929/java-net-socketexception-connection-reset
Uma das coisas que esse link fala é de uma ferramenta pra sniffar o que tá acontecendo na rede. Olha lá.

Espero que ajude…
