Very often there is a need to look at source code from Java files especially if you are an Oracle Applications developer. OA Framework code is delivered as class files and not as java source.

I have used various java decompilers over the years. The best and the most efficient to use seems to be the JD-GUI decompiler.

This has a few nifty features and the ones that stand out are:

• It can open up zip files to reval class files in the hierarchy.
• Additionally you can choose to save the entire package as source files. It does a batch decompile and returns a zip file.
• And yes you can view and save individual files as source code too.

Definitely recommended.
