| Exception Class | java.lang.SecurityException |
| Message | class.method: Only fully trusted classes can have native methods as members. |
| Possible Causes | The native keyword has been used on a method that is a member of a class that is not loaded with full permissions (for example, an unsigned applet). This exception is thrown only if an attempt is made to invoke the native method. |
| Possible Solutions | Digitally sign your applet requesting full permissions. |
