Solved :"java.io.IOException: Cannot run program "jad" (in directory............" error in eclipse during decompiling plugin

I was getting following problem after copying JAD plugin jar into eclipse 

plugin folder : 

java.io.IOException: Cannot run program "jad" (in directory 

"C:\Documents and Settings\Sai\.net.sf.jadclipse\1321168101468"): 

CreateProcess error=2, The system cannot find the file specified
    at java.lang.ProcessBuilder.start(Unknown Source)
    at java.lang.Runtime.exec(Unknown Source)
    at net.sf.jadclipse.JadDecompiler.decompile(JadDecompiler.java:160)

 Issue is because JAD exe was not available in system and I have just copied

plugin JAR.

To solve it I have downloaded JAD exe from JAD site :

http://varaneckas.com/jad/

and copied into eclipse folder ( for me it was following location ) 

D:\Software\eclipse-java-indigo-win32-x86_64\eclipse (\jad.exe)

after copy restart eclipse and it should fix the problem :) 

If still it does not work , check it out file association setting with JADEclipse class View 

as below in preference setting :
