How to create obfuscated package in Sun Java Wireless Toolkit 2.5.2?

Question

I would like to create obfuscated package of my j2me application for improving the size and performance.So, I have downloaded proguard from sourgeforge.net. I have put the proguard.jar into my C:\WTK2.5.2_01\bin folder.

When I try to create obfuscated package from project->package->Create Obfuscation package it raised the following exception

  Note: Some input files use or override a deprecated API.
  Note: Recompile with -Xlint:deprecation for details.
  Error: C:\Documents (The system cannot find the file specified)
  Obfuscation failed.
  Build failed

So, What is the cause of this error message and How do I obfuscate my application?

Answer 1

You should make sure you are using ProGuard's own WTK plugin, not the one from Oracle/Sun (which has a problem with spaces in path names). Cfr. ProGuard manual > JME WTK.

Answer 2

In j2me obfuscation requires Obfuscation tool.Progaurd is one of the good obfuscation tool.

U should install proguard in ur system.Then u goto Wirless toolkit ,select preferences,then the obfuscation setting, specifying the obfuscation tool path (Where ur progaurd in installed in ur system-proguard path).

Then after creating a project,after creating source file.For creating jar/jad u should select create package 4m wtk(wirless tool kit),instead of selecting create package,select "Create obfuscating /create obfuscation package" .Then the jad/jar is created with obfuscation files.

The obfuscation is same as normal java
