Web applicatio error with Ubuntu server and bsd

[devys]

Hi everyone,
I am developing a web application with jpct, using netbeans as IDE.
The application works fine on netbeans with the web application configuration setup, on a windows pc.
When I deploy the application on my ubuntu headless server and try to run it from a client with the jnlp page created by netbeans it gives an error. same error is received with netbeans on a BSD computer.
The error is :
Java.lang.ArrayIndexOutOfBoundsException: 0
   at xyzchess.main(xyzchess.java:149)
   at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
   at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

   at com.sun.javaws.Launcher.doLaunchApp(Unknown Source)
   at com.sun.javaws.Launcher.run(Unknown Source)
   at java.lang.Thread.run(Unknown Source)

and the line is :
BP1=Loader.load3DS("assets/cubo.3ds", 1.8f)[0];
where BP1 is an object3D.
the line does not give any issue on a windows OS, does anyone know why that could happen?
Thank you in advance for the time dedicated me,
kind regards
Devys

It's usually better to include the resources into your jart (or create an additional one) and access them via the InputStream that you can obtain from Class.getResourceAsStream().
