Can't you just rename the files (*.jad -> *.java)?

As per my understanding, you mean to ask how to convert class files to java files. If this is the query then the answer is that you unzip/untar the war/jar files to a folder and then use a decompiler to decompile the classes to java files. DJ Decompiler is one that I can suggest. However, there can be many available on the net.

thanks for replying,
what i want exactly is to rename a bulk amount of .jad files to .java files,
is there any tool to rename a directory of files from .jad to .java.

if you're on a Windows machine and they're all in the same directory

But the principle is sound, other operating systems have similar commands, some of them may even have an option to recursively process deeper directories.

Are you aware that Jad has an option that allows you to set the extension being used for decompiled files? That way there would be no need to rename the files.
