the phone's native functionality, including the phone-

cates and digital signatures. Many of these classes have
been newly added to the DoJa 5.1 profile.

Unlike the optional classes and methods in the core API packages
listed in Table 7.4, all classes and methods in the packages listed in
Table 7.5 are optional and they may not be present in all handsets. When
one of these packages is included in the Extension API, its operation may
be different depending on the manufacturer. Any call to a method that is
not supported on the target hardware causes the framework to throw an
UnsupportedOperationException
.
