how to convert a jar/war file of .class files to a folder containing .java files

[karthik sreeram]

HI ,
I want to know how to convert a .jad file to .java file,
i have large number of .jad files[around 4000] to .java files,
is there any tool to do this,
please reply me , if you know about it,
thanks in advance

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

[Chetan Raju]

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.

ren *.jad *.java should work if im not wrong

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.

Write a Java program to rename the files.

Thanks the renaming utility is working , but it is renaming the files in the current directory only,
but i want to rename the entire directory tree containing .jad files to .java files, how can i?

[Ulf Dittmer]

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.
