Default How to inspect/extract the contents of a .COD file?

Please Login to Remove!

I'm new to the BlackBerry platform (and mobile java in general), so I'm still getting my bearings. I'd like to be able to inspect existing blackberry applications to see how they use certain APIs. To do this, I'd like to be able to get out the Java .class files from a compiled application, so I can decompile them using standard Java tools.

Unfortunately, I've been unable to find documentation about what the .COD file format is. At a first level, it is often a ZIP file. But when it is a zip it usually contains other .COD files, which identify as "Compiled PSI (v1) data". I've been unable to find information on how to inspect, extract, or convert these. Are there tools or documentation that will help me?

Thanks for any help you can pass my way,

Hi, Richard!

You can't decompile cod files using existing java tools, since cod file doesn't contain class files.
.cod is native blackberry binary format.

I suggest you to review code of open-source applications. Blackberrytools or bbgolf, for example.

There's a reverse engineering blog that describes some progress in reversing the COD file format (""), but i don't believe a tool is provided to do the reversing for you.
