The CDC platform is implemented to support Advanced Graphics and User Interface Optional Package for the J2ME Platform, Personal Basis Profile 1.1, and the Connected Device Configuration (JSRs 209, 217 and 218). The AGUI API combines the PBP API and a subset of Java Platform, Standard Edition (Java SE) Swing capabilities.
Java ME Platform SDK version 3.0 supports CDC projects running as standalone applications. This means the CDC project structure and behavior are much the same as that of CLDC projects.
Note - An Xlet cannot be run standalone. It depends upon an application manager to manage its life cycle (its state) and system services. Xlets are not supported in this release.
Like MIDP projects, a standalone CDC project requires a main application class that includes a method named main() that handles class loading, object creation, and method execution. The application interacts directly with the Java runtime environment to manage its own life cycle and system resource needs. When the main() method exits, the standalone application terminates.
