[systat]

Hi, I am using netbeans to deploy my webstart app, and while it works fine when runned like normal applications, when I try to run it like Web Start I get this.

I put the -Djava.library.path=\lib as VM arguments.


Please help.

Sure, here you go, it is netbeans generated

Using natives in Webstart does not work by setting "-Djava.library.path". Take a look add the JNLPs for lauchning the demos http://www.lwjgl.org/demos.php. They use the extension mechanism to link to the LWJGL libraries on the lwjgl homepage.

If you don't want to link to it, you have to add per platform resources to the jnlp files like in the extension descriptor:

I managed to get it to work, but when I try to run jnlp from other computer it keeps crying that resource C:\sbkaojbakbo\Documents and Setting\myresource\someimage.png can't be found 

[cylab]

You are probably trying to load an image from a file on disk. That does not work with webstart. You have to put your resources in jars and use the this.getClass().getClasloader().getResourceAsStream("/path/to/your/resource/in/a/jar") to load it.

[systat]

No, I use SLICK, I don't need to use that, anyway, I managed to run it on my DESKTOP computer(the server is runing on my laptop), and one of my friends managed to run webstart, but one, got this error.

I don't have slightest idea what is causing it.

Maybe try getting him to clear his webstart cache and re-try. Webstart is usually more bullet-proof than what you're experiencing. But sometimes when you start off with a faulty jnlp or jars they can stick around in the cache and stuff up the program later.
