I am writing a shellscript in which I want to obtain original Javacode from a bulk of jar files.I am unjaring them successfully and then I have to decompile the class files to obtain the original java code.

While using "javap" from shellscript I am not getting the complete java code.Therefore I have to use some other Linux based java decompiler which can be called from shellscript to perform the bulk decompilation.

Please provide me with some Linux based decompiler(preferably freeware) which I can call from shell-script to act upon my class files.

I use jad http://www.varaneckas.com/jad - no source code but binaries available (even statically linked which should always work as long as you are on a supported architecture)

Here is a pointer to various Linux based Java decompilers: http://strategoxt.org/Transform/JavaDecompiler
