This chapter gives an overview of the implementation architecture, and the interaction and roles of the various entities that comprise the Java ME platform, as a Symbian OS subsystem.[82] The next chapter deals exclusively with how the Symbian OS Java ME subsystem acts as an abstraction layer for Java applications to make them use the same API calls as native Symbian OS applications. These two chapters are also highly valuable for engineers who work in systems development and integration.
There are a few widespread misconceptions about the Java ME subsystem architecture that will be shattered after reading this chapter. When you have finished, you will easily spot the four mistakes in a sentence such as 'The KVM aborted the MIDlet installation'.
Java Applications and Symbian OS
From the point of view of the Symbian OS architecture, the Java ME subsystem is a replaceable component that Symbian OS licensees can extend, customize or replace altogether. Additionally, the Java ME subsystem, as a whole, is a native application just like any ...
