[JAVA3D] Using vrmlloader in applet

[Siau Tan Long]

I am trying to load a wrl file using vrml97 class.     This is the applet code to load "mesh.wrl" ....   public void init() { ... URL path=getCodeBase(); URL  filename = new java.net.URL(path.toString() +  "mesh.wrl"); Scene loaderScene = null; VrmlLoader vm=new VrmlLoader();  try {      loaderScene =vm.load(filename);  }  catch (Exception e) {      System.err.println("Exception loading file: " + e);      e.printStackTrace();       System.exit(1);  } ....   }       This is the error message:   Exception loading file: java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader) java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader)  at java.security.AccessControlContext.checkPermission(AccessControlContext.java:272)  at java.security.AccessController.checkPermission(AccessController.java:399)  at java.lang.SecurityManager.checkPermission(SecurityManager.java:545)  at java.lang.SecurityManager.checkCreateClassLoader(SecurityManager.java:610)  at java.lang.ClassLoader.<init>(ClassLoader.java:234)  at java.security.SecureClassLoader.<init>(SecureClassLoader.java:79)  at java.net.URLClassLoader.<init>(URLClassLoader.java:113)  at com.sun.j3d.loaders.vrml97.impl.Loader$7.run(Loader.java:248)  at java.security.AccessController.doPrivileged(Native Method)  at com.sun.j3d.loaders.vrml97.impl.Loader.setWorldURL(Loader.java:245)  at com.sun.j3d.loaders.vrml97.VrmlLoader.load(VrmlLoader.java:105)  at Viewer.init(Viewer.java:93)  at sun.applet.AppletPanel.run(AppletPanel.java:344)  at java.lang.Thread.run(Thread.java:484)   java.lang.NullPointerException  at Viewer.init(Viewer.java:115)  at sun.applet.AppletPanel.run(AppletPanel.java:344)  at java.lang.Thread.run(Thread.java:484)       Is there any other things that I should do in order to load a VRML file in an applet?
