Hallo zusammen,
ich möchte einige Daten aus link entnehmen. Im Forum habe ich mit JDOM ein interessanten Lösungsvorschlag gefunden: link. Das wollte ich mal ausprobieren. Wenn ich die XML-Datei lokal (im gespeicherten Zustand im Dateisystem) auslese funktionierts, über eine URL erhalte ich diese Exception:
[code=Java]

Das ist mein Java Code:
[code=Java]
package reader;
import java.io.IOException;
import java.net.URL;
import java.util.List;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;
public class Reader {
public static void main(String[] args) {
try {
URL url = new URL("http://www.google.com/ig/api?weather=berlin&hl=de");
Document document = null;
SAXBuilder builder = new SAXBuilder();
try {
document = builder.build(url);
// document = builder.build(new File("/home/spree/Arbeitsfläche/wetter.xml"));
} catch (JDOMException e) {
System.out.println("Fehler");
e.printStackTrace();
}
Element root = document.getRootElement();
System.out.println(root.getName());
List<Element> list = root.getChildren();
Element el=root.getChild("weather");
List <Element> el2=el.getChildren();
for (Element a : el2) {
System.out.println(a);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
[/code]
Danke im Voraus...
