Actually, it is a know problem for Oracle. Anyway, exception appears before the applet starts. Sometimes it has not an influence on the applet and it works without problem. Sometimes the applet is not loaded at all. In this case to resolve the issue you need to do the following steps: Open Java Control Panel Open Advanced tab Expand Java Plug-in item Uncheck Enable the next-generation Java Plug-in Click Apply BUT!... Sometimes Enable the next-generation Java Plug-in checkbox is grayed out. In this situation follow the steps below to disable new java plugin via registy and see how it goes. Go to start, type regedit.exe and press Enter. Navigate to the location below: HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in Navigate to the subfolder of Java Plug-in. It should be something like:1.6.0_29 Set the dword value of  "UseNewJavaPlugin" to 00000000 to disable new java plugin. Close the registry editor. Free Web Directory - Add Your Link
