Whenever I try the audio clip, I get this error:
java.net.MalformedURLException: no protocol: /Users/videogames/Documents/workspace/TryApplets/res/adv.wav---------
What's the problem? Here's the code for the program. (I use a mac, if that matters at all)
package game;
import java.applet.*;
import java.net.*;
public class sound {
/**
* #param args
*/
public static void main(String[] args) {
try {
URL url = new URL("/Users/videogames/Documents/workspace/TryApplets/res/adv.wav");
AudioClip clip = Applet.newAudioClip(url);
clip.play();
} catch (MalformedURLException murle) {
System.out.println(murle);
}
}
}
An URL must start with something like http://.. or file://... The URL shown does not, it is not a valid URL.
Valid protocols for the URL class are
http, https, ftp, file, and jar
so try
URL url = new URL("file://Users/videogames/Documents/workspace/TryApplets/res/adv.wav");
If in doubt read the API
http://docs.oracle.com/javase/7/docs/api/java/net/URL.html#URL(java.lang.String)

I need to write a Java program that opens a PDF file at a named destination. The file test.pdf contains the named destination "DestinationX" on page 2. The program opens the PDF file but does not go to the named destination. How do I get to the named destination?
import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
public class MyLauncher {
static void openFileAtNamedDest(){
if (Desktop.isDesktopSupported()) {
try {
URI myURI = new URI("file:///C:/test.pdf#nameddest=DestinationX");
Desktop.getDesktop().browse( myURI );
} catch (IOException e) {
e.printStackTrace();
}
catch (URISyntaxException e) {
e.printStackTrace();
}
}
}
public static void main(String[] args) {
openFileAtNamedDest();
}
}
According to the spec, the format of your URL is correct. The only question is what application you are actually launching via browse(). I think it acts the same way as if you had double-clicked the file's icon on your desktop: it will launch whatever application is registered as the default handler for PDFs.
Acrobat should be able to handle a URL with a named destination, but other PDF viewers may not support it.
So I have this Code:
import java.applet.Applet;
import java.applet.AudioClip;
import java.net.URL;
public class SoundTest {
public static void main(String[] args) throws Exception {
URL url = new URL("Sprites/Omni's Tones/New tones/bubblespawn_01.wav");
AudioClip clip = Applet.newAudioClip(url);
AudioClip clip2 = Applet.newAudioClip(url);
clip.play();
Thread.sleep(1000);
clip2.loop();
Thread.sleep(20000);
clip2.stop();
System.out.println("end");
}
}
An error Appears:
Exception in thread "main" java.net.MalformedURLException: no protocol: Sprites/Omni's Tones/New tones/bubblespawn_01.wav
at java.net.URL.<init>(URL.java:586)
at java.net.URL.<init>(URL.java:483)
at java.net.URL.<init>(URL.java:432)
at com.edu4java.minitennis7.SoundTest.main(SoundTest.java:10)
How do I fix this? Thank you!
It seems that I need to add more lines to my code,
If you are running it inside the Applet then try with Applet#getCodeBase() and Applet#getDocumentBase
URL url = getDocumentBase();
AudioClip audioClip = getAudioClip(url, "music/abc.wav")
If it's running in a standalone application then choose one based on music file location:
// Read from same package
InputStream inputStream = getClass().getResourceAsStream("abc.wav");
// Read from music folder parallel to src in your project
File file = new File("music/abc.wav");
// Read from src/music folder
URL url = getClass().getResource("/music/abc.wav");
// Read from src/music folder
InputStream inputStream = getClass().getResourceAsStream("/music/abc.wav");
I am trying to play a .WAV in Java using the code from the javasound.info:
import java.net.URL;
import javax.swing.*;
import javax.sound.sampled.*;
public class LoopSound {
public static void main(String[] args) throws Exception {
URL url = new URL(
http://www.mediafire.com/listen/vgtpaigmj3un9ii/Untitled34.wav");
Clip clip = AudioSystem.getClip();
// getAudioInputStream() also accepts a File or InputStream
AudioInputStream ais = AudioSystem.
getAudioInputStream( url );
clip.open(ais);
clip.loop(Clip.LOOP_CONTINUOUSLY);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
// A GUI element to prevent the Clip's daemon Thread
// from terminating at the end of the main()
JOptionPane.showMessageDialog(null, "Close to exit!");
}
});
}
}
But I am getting the following error:
Exception in thread "main" javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input URL
at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1153)
at LoopSound.main(Wanderando.java:13)
I assume that the problem is with the URL itself and not the code, but I cannot for the life of me come across a service to upload and stream a .WAV file so that the program can capture the audio like in the original code with the :
http://pscode.org/media/leftright.wav
I am not sure if the code would have to be tweaked a bit for the to support mediafire's player or if there is another service for upload that support this.
Any help would be very appreciated.
Ok so i made a game in java and i exported it. In Eclipse everything works perfectly but when i export the jar there are some problems. When you collide with another rectangle it should play a sound (In eclipse it works but not exported).
Here is my class for sounds:
package sound;
import java.io.InputStream;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
public class GameSounds
{
static String hitPath = "/resources/8bit_bomb_explosion.wav";
public static synchronized void hit()
{
try
{
InputStream audioInStream = GameSounds.class.getResourceAsStream(hitPath);
AudioInputStream inputStream = AudioSystem.getAudioInputStream(audioInStream);
Clip clip = AudioSystem.getClip();
clip.open(inputStream);
clip.start();
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
and i used java -jar ProjectZero.jar to open up the console while playing and here is the error i get when it should play a sound:
java.io.IOException markreset not supported
at java.util.zip.InflaterInputStream.reset(Unknown Source)
at java.io.FilterInputStream.reset(Unknown Source)
at com.sun.media.sound.SoftMidiAudioFileReader.getAudioInputStream(Unkno
wn Source)

at sound.GameSounds.hit(GameSounds.java14)
at main.Main.doLogic(Main.java136)
at main.Main.run(Main.java100)
at java.lang.Thread.run(Unknown Source)
I tried exporting the resources into the jar but no success.
I tried putting the resources folder in the same folder with the jar but it doesn't work either.
Java Sound requires a repositionable input stream. Either use getResource(String) for an URL (out of which JS will create such a stream), or wrap the original stream to make it so.
E.G. copied from the Java Sound info. page.
import java.net.URL;
import javax.swing.*;
import javax.sound.sampled.*;
public class LoopSound {
public static void main(String[] args) throws Exception {
URL url = new URL(
"http://pscode.org/media/leftright.wav");
Clip clip = AudioSystem.getClip();
// getAudioInputStream() also accepts a File or InputStream
AudioInputStream ais = AudioSystem.
getAudioInputStream( url );
clip.open(ais);
clip.loop(Clip.LOOP_CONTINUOUSLY);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
// A GUI element to prevent the Clip's daemon Thread
// from terminating at the end of the main()
JOptionPane.showMessageDialog(null, "Close to exit!");
}
});
}
}

I have written the code which downloads the file from FTP server. Since I have my FTP server locally and I want to access like "ftp://localhost/alfresco". It was alfresco's FTP.
I have the following Code
public class FtpTransfer {
public static final void main(String[] args)
{
FTPClient ftp = new FTPClient();
FileOutputStream br = null;
try
{
ftp.connect("ftp://localhost/alfresco");
ftp.login("admin", "admin");
String file = "KPUB//Admin//TMM//Pickup//TMM_TO_ARTESIA_06152010220246.xml";
br = new FileOutputStream("file");
ftp.retrieveFile("/"+file, br);
System.out.println("Downloaded...");
}
catch(IOException exception) {
System.out.println("Error : "+exception);
}
}
}
The following exception occurs.
Error : java.net.UnknownHostException: ftp://localhost/alfresco
Please let me know how should I give the FTP Host Address?
FTPClient f = new FTPClient();
f.connect("localhost");
f.login(username, password);
FTPFile[] files = listFiles(directory);

Here is an example demonstrating connection to a server, changing present working directory, listing files in a directory and downloading a file to some specified directory.
package test;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.SocketException;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPFile;
public class FtpTransfer {
public static final void main(String[] args) throws SocketException, IOException {
FTPClient ftp = new FTPClient();
ftp.connect("ftp.somedomain.com"); // or "localhost" in your case
System.out.println("login: "+ftp.login("username", "pass"));
ftp.changeWorkingDirectory("folder/subfolder/");
// list the files of the current directory
FTPFile[] files = ftp.listFiles();
System.out.println("Listed "+files.length+" files.");
for(FTPFile file : files) {
System.out.println(file.getName());
}
// lets pretend there is a JPEG image in the present folder that we want to copy to the desktop (on a windows machine)
ftp.setFileType(FTPClient.BINARY_FILE_TYPE); // don't forget to change to binary mode! or you will have a scrambled image!
FileOutputStream br = new FileOutputStream("C:\\Documents and Settings\\casonkl\\Desktop\\my_downloaded_image_new_name.jpg");
ftp.retrieveFile("name_of_image_on_server.jpg", br);
ftp.disconnect();
}
}
Try remove protocol ("ftp://") from your url.
And please, look at the example.
The FTPClient.connect() method takes the name of a server, not a URL. Try:
ftp.connect("localhost");
Also, you may need to put alfresco somewhere else. If it's part of the file path,
String file = "alfresco/KPUB//Admin//TMM//Pickup//TMM_TO_ARTESIA_06152010220246.xml";
