[solved] Windows\lwjgl-2.6 sample lesson1 is not working

[Cottonwood]

I want to try it with linux/debian (Knoppix). And I don't understand why java doesn't find lwjgl in java.library.path.

As you can see it is in. What please is the problem?

[jediTofu]

Wow, it definitely seems like your computer is in tip-top shape.  I wonder if it could be some type of Unicode problem since you're using another language, but that wouldn't make sense.  I really wish that I could recreate the error; this is definitely crazy.  


As for Linux, (1) you're using old files and the old way to test and (2) your java.library.path should be "native/linux" or "./native/linux".  Please read "Testing LWJGL" at the bottom here:
http://lwjgl.org/wiki/index.php?title=Downloading_and_Setting_Up_LWJGL

[Cottonwood]

Thank you. Just a joke in between: The test program org.lwjgl.test.WindowCreationTest is working and as I switched to full screen mode my linux window within the sun virtual box became the size of the WindowCreationTest window. Should be the other way around. (upper picture)

No problem. I reboot from linux cd image and renew the linux hdd installation. So I thought. But it remains that small linux window.

No problem. I have a working XP image. That will help always.

Edit: Now again it is as it should be. (lower picture)

[Cottonwood]

Meanwhile I could test Lesson1 under linux/debian (Knoppix). It works fine:

root@Microknoppix:/media/sda2/java/lwjgl# java -cp .:res:jar/lwjgl.jar:jar/lwjgl_test.jar:jar/lwjgl_util.jar:jar/lwjgl_fmod3.jar:jar/lwjgl_devil.jar:jar/jinput.jar: -Djava.library.path=native/linux Lesson1
OpenAL Tutorial 1 - Single Static Source
[Menu]
p - Play the sample.
s - Stop the sample.
h - Pause the sample.
q - Quit the program.
Input: p
Input: q
root@Microknoppix:/media/sda2/java/lwjgl#

As you can see here, there is only one "Input: " prompt between p and q.
When I tried it under Windows there were more prompts and I had to enter the q twice.
Can that stick together with the termination error?

I noticed that problem on my Windows machine, so I fixed it (very) recently on the tutorial, so I don't think that's the problem, but could have been.  The other way I was doing input shouldn't have caused that crash, as it didn't on my machine.

One thing you could do is try and see if you can catch the exception, but it looks like you can't.  Worth a shot anyway.  Add this code:

public static void main(String[] args) {
  try {
    new Lesson1().execute();
  }
  catch(Exception ex) {
    ex.printStackTrace();
  }
}

[Cottonwood]

Sorry. There is no difference.

You're right. The new version didn't touch the problem.

[jediTofu]

   Sorry, there's got to be a problem with this Windows machine; it worked on Linux, right?  Search google for "javaw fehler in anwendung" or "javaw application error."  It could be your registry.

[Cottonwood]

Yes, it worked on Linux. But that was what I expected. It has a totally different native code and the error happens within the native code.
I googled for "javaw application error" and found out that that doesn't match my problem.

But I found something else. Someone wrote that it could work with msjava. Are you using Oracle Java too?

[jediTofu]

Yes, I'm using Oracle Java.

Have you tried a Nightly Build or an Older Release?  If it does not crash in 2.5 and it is in fact a native code problem, we'd at least know where to look.  You could also try running Windows in safe mode; worth a shot.  Wish I was more help 

[Cottonwood]

Last night I did a complete check with Kaspersky 11. No problems found.

Today I first tried the Nightly Build as well as the 1.5. Same problem.

Then I wanted to try it in safe mode. And Windows began joking with me. My XP was no longer activated. Something like "3 days left for activation - since windows was first activated on this computer, the hardware on the computer has changed significantly. Due to these changes, windows must be reactivated within 3 days-"

And Eclipse coundn't find the OpenAL library:

org.lwjgl.LWJGLException: Could not locate OpenAL library.
	at org.lwjgl.openal.AL.create(AL.java:153)
	at org.lwjgl.openal.AL.create(AL.java:104)
	at org.lwjgl.openal.AL.create(AL.java:203)
	at Lesson1.execute(Lesson1.java:117)
	at Lesson1.main(Lesson1.java:111)

To show you that there is no difference between safe and regular mode I repeated it with a cmd window. This was with a boot in safe mode:

There is absolutely no difference in the result of the set commands.

Do you have an idea what's to do to run it in safe boot mode?

[Cottonwood]

Now I reduced the code to these statements:

import org.lwjgl.LWJGLException;
import org.lwjgl.openal.AL;
 
public class Lesson2 {
    public static void main(String[] args) {
        // Initialize OpenAL
        try{
            AL.create();
        } catch (LWJGLException le) {
            le.printStackTrace();
            return;
        }
    System.out.println("Program terminates.");
    }
}

Even now the error happens. Any idea?

[Cottonwood]

I inserted one more statement at the end of the code: "    AL.destroy();". Now it works.
I found it here: http://lwjgl.org/javadoc/org/lwjgl/openal/AL.html

Can anybody change the sample within the tutorial? Here's the working code:

Wow, duh, I feel dumb.  I updated the source code on the 1st tutorial.  At least that one is good now.

It's still odd that it happened on your systems and not mine.
