How to get Java code into a Word document

I have a number of Java source files that I need to include in a technical document (MS Word format). Is there a tool that will take all the source files for a project and either create a new word document or import them into an existing word document? I would like to preserve the original source code formatting and it would be great if file name headings were automatically added to the word document, though I can live without this latter capability. Thanks for any help you all can provide.

I am fairly certain you could write a Word macro to get all the files with a certain extension in a certain directory and format them any way you liked.

you can use some extenral utilities like textpad and then try to copy form there to word
