Since you have static members (MenuItem[] menu), you must use a static
inner class (MenuItem). Just change your declaration of the MenuItem
class to be static.
'menu' is static in the test_jsp class, which means that it is
initialized at class load-time (before any instances of the class have
been created). MenuItem is not accessible until after an instance of
test_jsp has been created, so you have a paradox. The solution is to
make them both static. Or make them both non-static. Whichever you prefer.
