What version of JDK are you using. I was having essentially the same problem. 
It turns out for me that Java could not find the package org.objectweb.asm when 
trying to import org.objectweb.asm.ClassVisitor and org.objectweb.asm.Opcodes.

The solution that worked for me was installing default-jdk (which in turn, 
installed openjdk-6-jdk for amd64). Previously I just had sun-java6-jdk 
installed.

I'm running Ubuntu 10.04.

Hope this helps.

when I try to open the dex2jar.bat in notepad looks like this

@echo off
set CLASSPATH=
FOR %%i IN ("%~dp0lib\*.jar") DO CALL "%~dp0setclasspath.bat" %%i

java -cp "%CLASSPATH%" pxb.android.dex2jar.v3.Main %*

where I have to modify in this file.

And, when I try to run in second one... get the error look like this

C:\Users\Administrator\Desktop\project\androidtutorial\dex2jar-0.0.7.8-SNAPSHOT>
