[gfcf14]

Hi. I've been able to develop a simple racing game in Java through help from this site and what I could learn from tutorials, but now I've found myself stuck again (the forums with my questions are here http://www.dreaminco...arch_filter_app[forums]=1&view_by_title=1). I have given my project a webstart so that I can send it to friends who would like to see it. But I'm experiencing problems with the performance.

I am able to run my game through the compiler (I use Netbeans) and it seems to work fine, with music and effects (I used http://www.javazoom..../javalayer.html for the MP3s to be played), but when I clean and build to create a JAR and run it without the compiler's help the cars, which move in the compiler, don't move, and no action happens. AT first I thought it was the sound, I was using the audiostream library from sun (see here http://stackoverflow...-sound-in-java) to play wavs for the effects at first, but I had noticed then that when I wanted to make a JAR it would be created, but for some reason the compiler deletes whatever that has to do with it, so I decided to use this code instead (http://www.anyexample.com/programming/java/java_play_wav_sound_file.xml) to play the wavs. It works nicely in the compiler, and doesn't mention any infringement of copyright or anything that would affect the code. So I cleaned and built again to see if the JAR would run well, but I get the same error.

I'm using an ActionListener with a swing Timer to recognize the actions every 5 milliseconds, and I didn't start my project as a Desktop Application (i'm not sure if that would have to do with this). My project also depends heavily on the dispose() and new creations of JFrame classes to work (I used that to transfer from level to level), so would that be the problem? I've also been thinking that maybe since the MP3 playing depends on another JAR (the one in http://www.javazoom....javalayer.html) that maybe the creation of the game's JAR interferes with the usage of this other JAR, and the error of the sounds not being played stop the game from working, would that be possible? Thank you in advance for any help!

I'm posting the class for the Level 1 here, but if you want to see the others, go here: http://www.dreaminco...1&#entry1262481 . I haven't posted them here because nothing really serious has changed in them.

Did you build your jar through your ide, and did you add the external jars to your build path?

[pbl]

What does your manifest.mf file looks like ?

Better to do it by hand and never trust the IDE (or the way I use it )

http://download.orac...asicsindex.html

[gfcf14]

@nick2price: I built my JAR through the clean and build option of NetBeans, but I didn't change anything in the build path or any options given. But do you really have to specify if you need to include another JAR in the build even if you're already using it as a source?

@pbl: My manifest says:
Manifest-Version: 1.0
X-COMMENT: Main-Class will be added automatically by build
It's just 1KB. Should it be bigger, or should it include anything else? I'm definitely gonna look up your link to try and do it by hand

Obviously the built didn't update it should be
Main-Class: racemaster/theClassHoldingTheMainMethod.class

Sorry my bad

Main-Class: racemaster/theClassHoldingTheMainMethod

*Edited sorry you shouldn't put the .class

...the error of the sounds not being played stop the game from working, would that be possible?

Yes. Make sure you have included all necessary jars in the jnlp, the link to which doesn't currently work btw...

[gfcf14]

Mr. pbl, I created a JAR in the way that was explained in the link you provided me using command prompt, and checked with the jar tf try9.jar (the jar try9 was my 9th unsuccessful try), and it contains all of the files I meant to put in the jar for my project. However as I try to open it I get the following message:

Exception in thread "main" java.lang.NoClassDefFoundError: racemaster/MainMenu/class
Caused by: java.lang.ClassNotFoundException: racemaster.MainMenu.class
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: racemaster/MainMenu.class. Program will exit.

So I tried opening with JRE. And I get a message box which tells me "Could not find the main class: racemaster/MainMenu.class. Program will exit."

I thought that maybe the Main class wasn't specified. So I created a MF file following your comment: Main-Class: racemaster/MainMenu.class (MainMenu is the main class). So I try creating the JAR again and I get the same thing. I'm not sure why since I'm apparently specifying which is the main class.


@g00se: I'm not really sure how to specify what files to use to build the jar in NetBeans, but in Properties->Build->Packaging I noticed the line that says "Exclude from JAR File:" with the following extensions: **/*.java,**/*.form . I thought that maybe not having the .java files would hinder the performance of my jar, so I erased the **/*.java and built again. I then tried to run the JAR through command prompt, and it runs, but when I get to the part where the first MP3 sound is played (the first sound ever), I get an error message in the command prompt:

exception

The line 335 at Level1Board.java says the following:

readysetgo.play();

readysetgo is a MP3 variable, the first sound of any level. In my MP3 class, the play() method is

public void play() {
        try {
            FileInputStream fis     = new FileInputStream(filename);
            BufferedInputStream bis = new BufferedInputStream(fis);
            player = new Player(bis);
        }
        catch (Exception e) {
            System.out.println("Problem playing file " + filename);
            System.out.println(e);
        }

        // run in new thread to play in background
        new Thread() {
            public void run() {
                try { player.play(); }
                catch (Exception e) { System.out.println(e); }
            }
        }.start();




    }

It's really weird because when I run the program in NetBeans the sounds play perfectly, showing no error in the directory from where the sound is coming.

Also, I tried running the jar before actually changing the **/*.java part, and I get the same error as above.

Something I forgot to mention. While my jar is building in Netbeans, the compiler gives me the message "Note: Some input files use unchecked or unsafe operations.Note: Recompile with -Xlint:unchecked for details." But I'm not sure if that should be a problem, should it?

Sorry, my mistake, you do not put .class

so should be

Main-Class: racemaster/theClassHoldingTheMainMethod

adding the .class will look for the class class under theClassHoldingTheMainMethod

[gfcf14]

I should've noticed, it becomes redundant to look for a class with the name class. But I'm still getting the same mistake

Exception in thread "main" java.lang.NoClassDefFoundError: racemaster/MainMenu
Caused by: java.lang.ClassNotFoundException: racemaster.MainMenu

Could not find the main class: racemaster/MainMenu. Program will exit.

When I open the file on Netbeans, I can set the main class through the project's properties, but is there any other way to do it? Command prompt doesn't seem to recognize the manifest

Are you sure your

public static void main(String[] args)

method is in MainMenu ?

[gfcf14]

Yes. Although the MP3 class contains a psvm method that the programmers of it (http://introcs.cs.princeton.edu/java/faq/mp3/MP3.java.html) wrote for testing purposes. Would this affect the recognition of the Main class? And I also have one in the LastFrame class (the "credits" screen after the game is completed), though this one is commented out.

No thats OK. Actually all Java class should have a main() method for unit testing.
That is why you have to put in the manifest which one to use

Can you enter the command you enter at the console prompt to jar your application and from which directory you enter it ?

[gfcf14]

Ok. The project is on my flash drive, which is H:/ . In command prompt, I enter

h:

to access the flash drive. From the I enter

jar cvfm try10.jar H:\COP2805\RaceMaster\src\racemaster\racemastermanifest.mf H:\COP2805\RaceMaster\src\racemaster

where H:\COP2805\RaceMaster\src\racemaster is the address in the flash drive where the rpoject sources are. The manifest racemastermanifest.mf is located in that folder as well.
After the jar building process ends, since I was doing all the commands in h:, the jar is created there. So when I run the jar in command prompt I enter

java -jar H:\try10.jar

When I ran the jars created by Netbeans (named RaceMaster instead), they would run. But I'd still get a FilenotFoundException. When I try to run these, there is a ClassnotFoundException, namely the main one.

You should probably create a 'music' directory under src and put your MP3 files in there. Load with

InputStream in = getClass().getResourceAsStream("/music/x.mp3");

Not good... you do not want to Jar \COP2805\RaceMaster\src\racemast\....
you want racemaster only that is your poackage root

you have to cd to
H:\COP2805\RaceMaster\src
and
jar cvfm try10.jar racemaster/racemastermanifest.mf racemaster

also I have a concern about your /src directory
Are you using an IDE that put the .java and .class in two different directories ?
If it is the case, it is not the .java files that you want but the .class files
