Applets :: Accessing External Resources - Play Particular Sound Whenever Button Is Pressed
May 4, 2014
I am quite new to developing Applets in java. I recently made an applet that will play a particular sound whenever a button is pressed. The sound files are placed in the same directory as the applet class file and i access them by using
The Applet runs fine in the appletviewer but whenever I try to open it using any browser like Chrome,IE,Firefox the applet loads but sound isn't played. I checked the java console and it showed
1. How do I allow the applet to get access to those files?
2. When the Applet is running from the local file system why CAN NOT I access those resources via getCodeBase() ???
3. I googled and found that I can sign a JAR and that can have full access to the computer. But how do I create a JAR from an applet (which has no Main method) while it asks me to point to the main class in the manifest?
im trying to play a sound when button is clicked. here is the following code
InputStream in; try { in = new FileInputStream(new File("failure1.wav")); AudioStream audios = new AudioStream(in); AudioPlayer.player.start(audios); } catch (Exception e) { }
just wondering why it does load;
i do get the warning
warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioStream is internal proprietary API and may be removed in a future release AudioStream audios = new AudioStream(in); warning: AudioPlayer is internal proprietary API and may be removed in a future release AudioPlayer.player.start(audios);
I'm working on an application and I would like to package my resources (icons, about dialog images, splash screen images, release version text, etc.) in the jar file I'm going to distribute for deployment. I would like to access these resources from the JAR file in my deployed code. But I would also like them accessible when I'm running the code in my Eclipse IDE. Is there a way to do this using only one code base?
My Eclipse project structure is src (folder) which contains my source code, bin (folder) which contains my class files and res (folder) which contains my resource files.
I am using the javapackager utility to create my deployment JAR and build a self-contained deployment .exe for deploying to Windows.
Is there a way to have the javapackager build a single JAR file from multiple sources (i.e. my bin and res folders)? What do I have to do in my code so that the same code can be used to load resources when I'm running in Eclipse and the self-contained deployment?
What I want to do is very clear, just play sound and pause it. The problem is that I can't pause the music. When I click the pause button music keeps playing .I have been working on for 2 hours. I can't find the mistake; what am I doing wrong?
public class MainC extends JFrame implements Runnable,ActionListener { private JPanel contentPane; private JTextField txtname; JButton btnopen; JButton btnSave; JButton btnplay;
I wrote the below program to set up and play the game breakout as an assignment for Stanford's CS106 programming class. I wrote it on my old mac running OSX 10.6.8, with the version of Eclipse JDK that works on that machine. When I tested it back on the mac, the program worked normally. But now I am using a Windows 8.1 computer with the corresponding version of eclipse, and when I test the program again, the sound effect I coded does not play. I get the following error message in console when the ball hits the paddle or brick, which previously caused the sound clip to play.
Exception in thread "Thread-4" java.lang.IllegalArgumentException: Requested value -120.0 smaller than allowable minimum value -80.0. at javax.sound.sampled.FloatControl.setValue(Unknown Source) at com.sun.media.sound.DirectAudioDevice$DirectDL$Gain.setValue(Unknown Source) at acm.util.SoundPlayer.setLineVolume(SoundClip.java:909) at acm.util.SoundPlayer.run(SoundClip.java:860) at java.lang.Thread.run(Unknown Source)
why my code would request a value below the min. I am using the mediatools class that is part of the ACM libraries we are required to use for the class to play the sound in question, found here: URL....I went ahead and tested all parts of the program and the missing sound effect is the only problem. Here is my complete code:
I do not think this is possible, but I'd like to confirm. If I have an HTML page that has an embedded Java applet, and that applet in turn renders an HTML document (within the applet window), is the HTML *within* the applet part of / accessible through the DOM for the parent page?
Ok, so I am trying to learn about JFrames and JPanels. I have figured out buttons, layouts, etc. What im having trouble with is accessing the label object from the ButtonHandler class since it is static and I need my JLabel to be non-static so that it can change. Basically, I want JLabel to change to a pre-determined text string once a button is pressed. Here's what I have so far
I have a filechooser that works how it should and if anyone enters anything with a dot that isnt .xml it shows an invalid file name message. However when I dont choose a file and press cancel it still says that because when my boolean hits false it's the first thing it hits in that section of code.
if(!writeSuccess) { //display output messages in JOptionPane JOptionPane.showMessageDialog(null,"Error, file name invalid", "Error", JOptionPane.ERROR_MESSAGE); } else { JOptionPane.showMessageDialog(null,"Export successful", "Success", JOptionPane.INFORMATION_MESSAGE); //close the form me.dispose(); }
If I want it to just close down without it saying anything is there sort of if statement I could do that would prevent this? But if it is an invalid file name it will still show that message?
I am new to Java, I am using Netbeans to create a simple GUI with one button that just says "play". I want this to play an mp3 file i specify. I have found code to simply play a WAV which works great.There is lots of information on the net about playing an mp3 but it's all long an complicated. There must be a simple way to just have java play an mp3 file.
I have tried running the java application without adding the site to site list in java security tab. But I get a sand box message as APPLICATION BLOCKED BY SECURITY SETTINGS. How to run the java application without adding the site to site list in java security tab.
I am making a game in java and i want to make a title screen. What I am trying to do is make a jpanel and load another jpanel when a button is pressed in one of the japenls. Here is the code for the runner
import java.awt.BorderLayout; import javax.swing.JFrame; public class Runner extends JFrame { // Have these set up so they can be seen everywhere public static final int GAMEWIDTH = 540; public static final int GAMEHEIGHT = 710; static boolean loading = false;
[Code] ....
here is the code for the jpanel that loads the other jpanel
In my java app there is a code which reads the properties file from src/main/resources folder.
Java Code:
@Component("mailerProperties") public class MailerProperties { private static Properties properties; public MailerProperties() { properties = new Properties();
[Code] ....
Now I need to create a jar file and also remove the properties file from src/main/resources folder and place it outside the jar file(in the same location as jar file) so that data inside it can be changed easily in future.
Question: Currently it uses ClassPathResource("mailer.properties") to read the prop file. What change I need to make to read it from outside the jar file...
I have one Project -"A".Inside of that I use, .XLS to read data.
Structure - A/src/TestData Inside of the TesetData - I have placed XLS files.
I have main method in TestDriver class.If I run this in Eclipse, running fine.But after exported to executable/runnable Jar, and ran via command line (command - jar -jar myjar.jar), I see issue: "Exception in thread "main" java.io.FileNotFoundException: srcTestDataTestCaseController.xls"
i want to list files from resources folder like this:
@ManagedBean public class galley implements Serializable { private List<String> list; @PostConstruct public void init() { list = new ArrayList<String>();
[Code] ....
but it give me a null pointer exception on fList .... The directory of resources is :
The error I get is as follows...When the page is loaded I get the following error: java.lang.SecurityException: class "com.myPackage. test.client. TaskApplet" does not match trust level of other classes in the same package
I created a game but want some music in it, and as I write in the title i want the sound to loop. This is the code fore the sound class i have:
Java Code:
import java.applet.Applet; import java.applet.AudioClip; public class Sound { private AudioClip clip; //all sounds public static final Sound ScoreSound = new Sound("/Score.wav"); public static final Sound BounceSound = new Sound("/Bounce.wav");
how to make a simple game. I am having trouble when it comes to adding sound though. It tells me to do this:
package net.game.Game;
import java.applet.Applet; import java.applet.AudioClip; public class Sound { public static final AudioClip BALL = Applet.newAudioClip(Sound.class.getResource("ball.wav")); public static final AudioClip GAMEOVER = Applet.newAudioClip(Sound.class.getResource("gameover.wav")); public static final AudioClip BACK = Applet.newAudioClip(Sound.class.getResource("back.wav")); }
What this does is it gets the sound file then gives it a name(BALL=ball.wav GAMEOVER=gameover.wav ect..) and then there is other code in other classes that call the sound so it will run but it keeps giving me an error and I don't know what to do. How can I get it to import the sound? Here is the error.
PHP Code:
Exception in thread "main" java.lang.ExceptionInInitializerError at net.game.Game.stuff.<init>(stuff.java:35) at net.game.Game.stuff.main(stuff.java:62) Caused by: java.lang.NullPointerException at sun.applet.AppletAudioClip.<init>(Unknown Source) at java.applet.Applet.newAudioClip(Unknown Source) at net.game.Game.Sound.<clinit>(Sound.java:7) ... 2 more
I have to write a program that asks the user to enter "air", "water", or "steel", and the distance that a sound wave will travel in the medium. The program should then display the amount of time it will take. The amount of time it takes sound to travel in air can be calculated as follows;
Time = Distance/1,100
The amount of time it takes sound to travel in water can be calculated with the following formula:
Time=Distance/4,900
The amount of time it takes sound to travel in steel can be calculated with the following formula:
Time=Distance/16400
Here is my code:
import java.lang.String; /** This program displays numbers padded with leading zeros. */
public class SpeedofSound { public static void main(String[] args) { double D; // declares this as double D = keyboard.nextDouble(); const double A = 1100; // declares this as a constant
[Code] .....
The following is the error I'm getting:
----jGRASP exec: javac SpeedofSound.Java error: Class names, 'SpeedofSound.Java', are only accepted if annotation processing is explicitly requested 1 error ----jGRASP wedge2: exit code for process is 1. ----jGRASP: operation complete.
Okay, so I'm looking for a way to synthesize sound, and from what I've found around the interwebs it seems amazingly complex. Is there really not a function like "sound(wavelength, time)"? Alternatively a way to use an integer array to determine the acoutstic pressure at a given time, or some other way to determine the pressure at a given time?
I am very much new to Java. I have just started learning event handling. Currently I am learning about Key Events. And am learning by doing. Well that is how one could learn anything in fact. I want to write a program in which the currently loaded image in the panel of a frame changes upon a key press say "Enter" or any other key.
