| Exception Class | java.lang.NoClassDefFoundError |
| Message | None. |
| Possible Causes | An untrusted class has attempted to load either a class marked with the @dll.struct directive or a class generated using the jactivex tool. Although this is really a security violation (not a class loader error), a NoClassDefFoundError is thrown for backward compatibility purposes. |
| Possible Solutions | Digitally sign your applet requesting full permissions. |
