Figure 1-2. MIDP packages
Note While the MIDP 2.0 specification suggests that MIDP 2.0 will most likely be paired with CLDC 1.1,
the JTWI compatibility platform only requires implementation atop CLDC 1.0. As a result, most current imple-
mentations of MIDP 2.0 are paired with CLDC 1.0. Historically, the MIDP 2.0 specification was moving faster
through the Java Community Process than the CLDC 1.1 specification.
Optionally, device vendors may also supply Java APIs to access device-specific features.
MIDP devices, then, will typically be able to run several different flavors of applications. Figure 1-3
shows a map of the possibilities.
Figure 1-3. MIDP software components
Each device implements some kind of operating system (OS). Native applications run
directly on this layer and represent the world before MIDP—many different kinds of devices,
each with its own OS and native applications.
