Exception in thread "main" java.lang.OutOfMemoryError: Java heap space about dex2jar HOT 14 CLOSED

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.

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

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