Dear all,

I would need some advise.

I have writen a java program to use in BB, but there is Java Decompiler available that make people to revert the program to editable source easily.

I am wondering, is there a way to protect my intellectual property ?
I have spent hours and hours to write the program !!

Do I need to give up all Java developement ?

[simon.hain]

the cod-files compiled with the rim jde (or rapc) are encrypted and can not be decompiled (at least not with reasonable amount).

It's a proprietary file format yes, but it is not encrypted. Try opening one up once with a hex editor, it has sections that are plain text readable.

Could you not simply use a Java code obfuscation tool and then run the rapc compiler on your obfuscated code?

Exerpt:

Minimal savings can be found by using short names for file paths, classes, methods and instance variables. Unlike .jar format, applications created in .cod format are tightly compressed and obfuscated

There are efforts to write a COD decompiler:

General consensus is that you don't need to do anything. Your sooper sekret IP is safe.
