Swing/AWT/SWT :: Continuous Audio Data Stream Not Working
Oct 15, 2014
I am trying to make my audio loop and i tried the code below
public void audioloop() {
AudioPlayer MGP = AudioPlayer.player;
AudioStream BGM;
AudioData MD;
ContinuousAudioDataStream loop = null;
try {
[Code] ....
But is not working. I was thinking may be API is not work with java 7 because i got the following warning (AudioStream is internal proprietary API and may be removed in a future release);

package timerApp;
import java.util.Scanner;
import java.util.Timer;
import java.util.TimerTask;
import sun.audio.*;
import java.io.*;
public class timerDriver
{
static int interval;
[Code]...
So I'm trying to make a program that plays an mp3 file after a timer reaches 0, but i keep receiving the error "could not create audio stream from input stream" the audio file is 3.44 MB and 00:03:45 minutes long if that's a problem

Just run the following code and move the mouse next to the text of the button and you will see exactly what I am talking about. Any way to prevent this continuous flash?
import java.awt.Dimension;
import javax.swing.JButton;
public class GUI {
public static void main (String[] args) {
javax.swing.JFrame frame = new javax.swing.JFrame();
javax.swing.JPanel panel = new javax.swing.JPanel();
[Code] .....

I wanted to know some hints on where to begin if I wanted to create a program which compares an audio file with real time captured audio. I found this website "[URL]...", but I think this would not do the job, so what are the basics of audio in java and how to compare audio files and see if they are compatible.

I a simple server that receives bytes using TCP and then saves them to a file stream.Through many tests I have seen that the first packet received is always just the filename with no other data. The second packet received only has one byte and it is the first letter of the input text file. After this all packets are sent correctly, but I can't seem to figure out what is messing up the second packet. It also appears that the last packet is written twice.
Here is an example Input/Output: [URL] .....
InputStream in = clntSock.getInputStream(); //server's input stream - gets data from the client
OutputStream out = clntSock.getOutputStream(); //server's output stream - server sends data to the client
byte[] byteBuffer = new byte[BUFSIZE];
int count = in.read(byteBuffer, 0, BUFSIZE);
String firstRead = new String(byteBuffer, 0, count);
[Code] ....
Another peculiarity to me is that the second to last packet is always just "-" and then the last packet has the remainder of the magic string which terminates the file output stream.
I am aware that it is not safe to make the assumption that the file name will be sent in one go before the loop, but I wil fix that later. I am not concerned about it at all now. THe problem si that the loop should account for any amount read in, but for some reason the first packet always contains one letter, and the second packet picks up around 16000 bytes later for some reason. Why would this be?I can't edit my above post so here is the code with code tags.
InputStream in = clntSock.getInputStream(); //server's input stream - gets data from the client
OutputStream out = clntSock.getOutputStream(); //server's output stream - server sends data to the client
byte[] byteBuffer = new byte[BUFSIZE];
int count = in.read(byteBuffer, 0, BUFSIZE);
String firstRead = new String(byteBuffer, 0, count);

Iam trying to upload jpeg image.
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
[Code] ....
In servlet the below code
DataInputStream din = new DataInputStream(request.getInputStream());
byte[] data = new byte[0];
byte[] buffer = new byte[50];
int bytesRead;
while ((bytesRead = din.read(buffer)) > 0 ) {
byte[] nData = new byte[data.length + bytesRead];
System.arraycopy(data, 0, nData, 0, data.length);
System.arraycopy(buffer, 0, nData, data.length, bytesRead);
data = newData;
}
What i see is servletinput stream does't have any values.It does't even enter while loop.

I am subclassing a Pane to be able to use my custom NGRegion:
public class MyPane extends Pane {
@Override
public NGNode impl_createPeer() {
return new MyNGRegion();
}
}
in MyNGRegion i override renderContent(Graphics g) for custom drawing
@Override
protected void renderContent(Graphics g) {
/* custom drawing */
}
The custom NGRegion gets drawn one time, but i want to continuously draw on every pulse.
i already tried a lot of things, but don't see how to do it properly:
using -Dprism.forcerepaint=true did not work.
overriding clearDirty() and set it

We created one web application which runs on tomcat 7.0.35 using spring mvc 3.0 . Its working perfectly on 32-bit windows machine in IE 8 on Windows 7 OS, when we tried to run this on 64-bit windows 2008 Server, jquery is not working. Also I populate data from Pop-up JSP to parent JSP, and it works 3/10 times only and does not work always.
We used the following jquery plugins in our project
jquery 1.8.3
jquery.ui.custom.1.9.2
jquery.ui.custom.min-1.9.

I'm trying to get a progress bar to work on my GUI.
This is what I have so far, the parameters are taken from another class that takes in an image in packets from a Raspberry Pi and stores them to a file on PC.
public void ImageInfoReceivedHandler(int sizeOfFile) {
progressBar.setMinimum(0);
progressBar.setMaximum(sizeOfFile);
progressBar.setIndeterminate(false);
[Code] .....
The println are printing out the correct values and they are being implemented in the methods, but nothing is happening in the GUI.
I have a thread setup in the GUI when a button is pressed
getImageButton.setText("Timer Started");
transmit = new transferImage(port);
lblImgProcess.setText("Getting Image, Please Wait");
transferThread = new Thread(transmit);
transferThread.start();
So the thread starts and image is then transmitted, does the progress bar need to be in that event handler?

setDefaultLookAndFeel is not working as i'm expecting.this is my code: URL....
import javax.swing.*;

import java.awt.event.*;
import javax.swing.text.*;
import java.io.*;
import java.text.*;
[code]....
after reading the oracle tutorial on how to make frames and reading FrameDemo2.java. URL....i thought setDefaultLookAndFeelDecorated(true); would give me a different decoration than the default windows 7 border.but toggling between true and false changes nothing, and changing setUndecorated does nothing either.what am i supposed to do to make it look like the one in theFrameDemo2 window?

I was suspecting I had a jButton not working, so I added a console print to test. See below. When I click the button, the console doesn't display anything. Am I using the button wrong?
private void jButtonUpdateItemsMouseClicked(java.awt.event.MouseEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}
I have also tried the following with the same results (or lack of).
private void jButtonUpdateMajorDeckItemsActionPerformed(java.awt.event.ActionEvent evt) {
System.out.println("click");
System.out.println(drawPreviousRectangle);//this is a boolean
}

I am trying to get a scrollPane working correctly, but not having any luck. The picture drawn in the center panel is quite large and goes off the screen. I visited URL... but I am missing something vital. Both tracks show, but there is no knob to do the scrolling.
public DViewer() {
super();
frame = new JFrame();
frame.setSize(Toolkit.getDefaultToolkit().getScreenSize());
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

I'm trying to make a simple window that displays 5 text fields on x number of rows, depending on what I set x to. Attempting to do this with GridBag Layout but I can't seem to get a new row started. The closest I can get is to repeat the same fields on the same row. I'm trying to modify the row by putting the code in a loop and setting gridy = i, that way each iteration should place the code lower than the first. I'm new with GridBagLayout so I'm probably missing something simple. The constructor with the loop is below. I've commented out code that doesn't seem to work but left the gridx and gridy.
public PAMCalculator()
{
setTitle("PAM Calculator");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(WIDTH, HEIGHT);
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints gridConstraints = new GridBagConstraints();
setLayout(gridbag);

I am adding a JTextArea to my JPanel with this code:
commentTextArea.setLineWrap(true);
commentTextArea.setWrapStyleWord(true);
commentTextArea.setVisible(true);
this.add(commentTextArea);
commentTextArea.setBounds(0, 0, 100, 100);
//commentTextArea.setLocation(0, 0);
Whenever I use setLocation(0,0), the JTextArea never moves. It is always in the top middle of the screen, not at (0,0). The same goes for setBounds(0,0,100,100) BUT the height and width are set this way, just not the location. Why is this?

I have written a drum machine using Java. Into said drum machine I list all 47 available MIDI drums. The instrument list is placed into a JPanel, along with a gridArray of checkboxes. The JPanel is then in turn added to a scrollpane. I have listed the MIDI drums in order of 'ground-up'. For example, the bass drum is generally at the bottom of most drum kits, so it is at the bottom of my MIDI drums list. Next up would be the snare, followed by the cymbals, and then by all the specialty percussives. Since most beats are started from the 'ground-up', laying to foundation, so to speak, I want the scroll bar of the scrollpane which houses the JPanel, which in turn houses the instrument list and the beat checkboxes, to be positioned, upon opening, at the bottom of the scroll pane. Nothing I have tried works. It always positions the slider somewhere in the middle of the scroll track. Below is a listing of just the buildGUI portion of the code, all the MIDI functionality has been removed to keep the size of the post to this forum down.
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class BeatBoxG
{
JFrame overallOuterFrame;
JScrollPane namesAndSquares;

I am having right now is that I don't know how to stop my music from playing? I am making a Connect 4 game with some audio to make it intuitive. Below is my code. This is my Music method.
public static void Music() {
try {
File music = new File("C:\Users\Ken\workspace\Assignment1\src\Mario1.wav");
AudioInputStream audioIn = AudioSystem.getAudioInputStream(music);
Clip clip = AudioSystem.getClip();
clip.open(audioIn);
[Code] ....
I called this method into a JButton i implemented into my main GUI.
if (e.getSource() == SoundOn){
Music();}
if (e.getSource() == SoundOff){
//What do I put here?
}
There is the method and my JButton.
