Hi,

Can i get a copy of the patch pelase. The link to the patch seems to be dead.
Any help highly appreciated.

waitting for fix the broken link

Hey s7ephen,

Are you still in the process of updating the site links? I would very-much like to get that patch.

Thanks.

I got the error below trying to run this with the latest patch, so I did some debugging.

Error:

java.io.IOException: no class ref found at offset: 0xc1

Turns out that the decompiler always think its decompiling Version 6 (_isVersion6 is always true).

net.rim.tools.compiler.codefile.DataSection:134:

_Version = 6;
if (_Version >= 6)
{
_isVersion6 = true;
fh = false;
z_eGZ = false;
z_e4Z = false;
z_e7Z = false;
}


I’m not sure if the above snippet is even required since those values are set again around DataSection:155. I added _isVersion6 = false; to DataSection:156 and now it decompiles my V5 cod without crashing.

Hi Guys Thanks for the app. Very Much Noob! I was wondering if someone might have a bit of a walkthrough to get this app up and running.
Thanks for any help!

When trying to compile it, e.g.:

javac ./net/rim/tools/compiler/codfile/AdvancedMemberRef.java

i get hundreds of errors like e.g.:

./net/rim/tools/compiler/codfile/AdvancedMemberRef.java:84: class, interface, or enum expected
package net.rim.tools.compiler.codfile;
^
./net/rim/tools/compiler/codfile/AdvancedMemberRef.java:86: class, interface, or enum expected

What is wrong with it?
I am using java 1.6.0_22:

# java -version
java version “1.6.0_22”
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)

And the code-formatting on this site is a kind of not working.
e.g. I had the “^” sign under the “b” from “public class a extends b” but not as the first position. The “code”-tag should keep the spaces, but doesn’t.
Ts,ts,ts…

Finally it works great.

Is it possible to change something on bytecode level (decompile directory) and recompile it to final .COD again??? Invert process of CODDEC.
Also, is it possible to transform .JAVA generated to source code level, and change and recompile again to .COD?

I got this notes when i patch the code you shared.

Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Ah, ok, this sounds not too bad.
Unfortunately I am far away from this deepness of machine and java code 😦
But it is good to know that it would be possible 🙂

I have finally done it to completely reverse to plain java source code. If someone needs helps advice me. Even recompilation is possible.
