I'm having trouble running this sample code for the gdata java library:
import java.net.URL;
import com.google.gdata.client.Query;
import com.google.gdata.client.blogger.BloggerService;
import com.google.gdata.data.Feed;
public class AccessBloggerSample {
public static void main(String[] args) throws Exception {
BloggerService service = new BloggerService("Testing-Blogger");
service.setUserCredentials("tmerachli#gmail.com", "XXX");
System.out.println("Google: " + BloggerService.getVersion());
URL feedUrl = new URL("http://minhchaunyc.blogspot.com/feeds/posts/default ");
Query query = new Query(feedUrl);
System.out.println("service: ");
Feed resultFeed = service.getFeed(query, Feed.class);
System.out.println("blogs: " + resultFeed.getEntries().size());
}
}
And I get the following error:

Any ideas why I'm getting this? I'm compiling and running my code through BlueJ and I extracted all the jar files into the lib directory of BlueJ and the code compiles.
You need to add guava to your Java Build-Patproject: http://code.google.com/p/guava-libraries/

Best regards,
I've been trying to experiment with the JavaFX MediaPlayer class, and found the following example code in a different thread:
import java.net.URI;
import java.net.URISyntaxException;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.stage.Stage;
public class test extends Application {
#Override
public void start(Stage primaryStage)
{
//Add a scene
Group root = new Group();
Scene scene = new Scene(root, 500, 200);
URI file = null;
try {
file = new URI("/home/thomas/voodoo.mp3");
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("POOR URI SYNTAX");
}
Media pick = new Media(file.toString());
MediaPlayer player = new MediaPlayer(pick);
player.play();
//Add a mediaView, to display the media. Its necessary !
//This mediaView is added to a Pane
MediaView mediaView = new MediaView(player);
((Group)scene.getRoot()).getChildren().add(mediaView);
//show the stage
primaryStage.setTitle("Media Player");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I adjusted the file path to point to a real audio file (/home/thomas/voodoo.mp3) and tried running it, but the console output is the following:

Exception running application test
Is there something wrong with my setup, or with my code?
Thanks for the help!
EDIT:
Changed to Media pick = new Media(new File("/home/thomas/voodoo.mp3").toURI().toString()); as per Nash's suggestion, but it still doesn't work. The console output is a little different now, though.

Exception running application test
The problem is your url /home/thomas/voodoo.mp3 that is not valid, indeed the scheme is missing as described into your error message (uri.getScheme() == null! uri == '/home/thomas/voodoo.mp3'), it should start with file:// as it is a file in your local file system such that it should be file:///home/thomas/voodoo.mp3.
But since it is too error prone to build the URI as you currently do because you must ensure that it is properly URL encoded (spaces should be for example replaced with %20) and you need to provide a valid scheme, you had better to use new File(path).toURI().toString() as proposed by Nash.
Try
Media pick = new Media(new File("/home/thomas/voodoo.mp3").toURI().toString());

I'm trying to parse a bit of JSON in Java by following this tutorial. Because it mentions nothing about org.apache.commons.io.IOUtils other than it imports it, I figured all it was used for it to convert an InputStream into a String. I have my own code for that, so I omitted it. Here is my code:
import java.io.*;
import java.io.InputStream;
import java.net.*;
import java.util.Scanner;
import net.sf.json.JSONObject;
import net.sf.json.JSONSerializer;
public class Net {
static String returnParsedIp() throws UnsupportedEncodingException, MalformedURLException, IOException {
String url = "http://httpbin.org/ip";
URLConnection connection = new URL(url).openConnection();
connection.setRequestProperty("Accept-Charset", "UTF-8");
InputStream response = connection.getInputStream();
String responseString = new Scanner(response,"UTF-8").useDelimiter("\\A").next();
//return responseString;
JSONObject json = (JSONObject) JSONSerializer.toJSON(responseString);
String Ip = json.getString("origin");
return Ip;
}
}
I then call the method from my main class with:
public class DDNS {
public static void main(String[] args) throws Exception {
String Ip = Net.returnParsedIp();
System.out.println(Ip);
}
}
However, it throws the following error:

Either you don't have the Apache Commons lang and io JARs in your CLASSPATH or you have the wrong version.
Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang.exception.NestableRuntimeException
This is Java 101. You need all the dependencies in the CLASSPATH in order to compile and run.
You have to add the commons-lang jar in yout project
