Re: ROMizing

Alex,

The way I understand your situation is that you want to create a standalone system that boots Linux, starts the Java VM execution, and automatically runs a preconfigured Java application. I didn't follow the bouny castle thread but essentially what you need is:

- The Java VM stack with all necessary system classes preverified in the bootclasspath, possibly ROMized. This configuration is automatically built with the normal phoneME build process so you don't need to do anything else here

- The application, packaged in a jar file including all libraries you need (such as bouncy castle) and preverified

- Tell the phoneME stack to execute your application on start-up and point it to the main class as well as the jar file

All of the above is easy to do and doesn't require any "tricks".

You ask about the ROMizer. You can find a description here:

http://java.sun.com/javame/reference/docs/cldc-hi-2.0-web/doc/architecture/html/Romizer.html

The ROMizer is a tool that takes a list of class files, loads the classes and resolves them, and then takes a snapshot of the layout of all resulting data structures in memory and builds a set of C files that represent that state. This is now linked into the Java VM. The result is that all ROMized classes are immediately available for execution when the VM starts up thus reducing start-up time considerably.

It is an alternate means loading and resolving classes if these classes are known at the time the Java VM stack is built. But it is only an optimization and therefore I don't think is required for your situation.

Let me know if this makes sense.
