Hi,

I want to obfuscate my code using proguard in eclipse plugin.

i found a below article to do it, but i am facing some challenges.

http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800901/How_To_-_Obfus...

problems in Obfuscating code and creating cod.

1) in step 4- I can't see extracted content of jar file if i extract jar file using " jar xvf SampleApplication.jar. i am able to solve this by extracting jar using winrar ( not sure if its correct way of doing it)

2)  step 5 and step 6, i am performing using proguard utility. ( i am using proguard 4.8). here if i ingore all warning while obfuscating then only i am able to do obfuscation.

3) in step 8 , its mentioned that run rapc.exe on obfuscated files, but when i checked rapc.exe requires .java or .jar file as input, how to run rapc.exe on class files?

one more question, in my project , there are many class files, Do i have to list all .class files while creating cod ?

or can i give directory name to generate cod?

General Questions :

1) has any one has tried obfuscating blackberry code using proguard?

2) also, is there anyway i can configure proguard directly in eclipse?

Thanks in advance.

I do shrink,obfuscate and optimize jar file using proguard.

then i use preverify command of RIM to preverify,

but after this I am not able to generate cod file using rapc command on obfuscated file. i get one or other error like Error:missing stack map in:com.app.controller at label 23

P.S : if i do only shrink using proguard, then after preverify I am able to generate cod using rapc command.

hence, as per my understanding , there is something wrong happening in obfuscation or optimisation.

I have tried verious options available in proguard for obfuscation, but no luck

so my questions is, what are the options to be used in proguard while obfuscation the jar file ?

is there is any other reliable tool for blackberry code obfuscation?

Thanks.
