    Thumbs up Access restriction error in eclipse (Solved)

    Hi, I'm trying to include J3D classes (Java3d) into my eclipse project. But when I write for example:
    Java Code:
    import com.sun.j3d.utils.universe.SimpleUniverse;
    Then I get an error saying "Access restriction: The type SimpleUniverse is not accessible due to restriction on required library C:\Programfiler\Java\jre6\lib\ext\j3ddutils.jar"

    The jar's is locked, because all files in "program files" always is locked. Could this be the problem? If so; How to get eclipse to change the classpath to another file with the J3D jar's?

    Also when I compile and run I get:
    Exception in thread "main" java.lang.Error: Unresolved compilation problem at IEC3D.main(
    Here is my whole code:
    Java Code:
    import com.sun.j3d.utils.universe.SimpleUniverse;
    import com.sun.j3d.utils.geometry.ColorCube;
    public class IEC3D {
    public IEC3D()
       SimpleUniverse universe = new SimpleUniverse();
       BranchGroup group = new BranchGroup();
       group.addChild(new ColorCube(0.3));
    public static void main( String[] args ) {
       new IEC3D();
    } // end of class Hello3d
    I found the problem, and suddenly it was fixed. I doesn't exactly know how it got fixed, but it was something with the path access... I think I included a path to some other jar's where I got access.
