Hi,

Could you give a description of what you would like to have happen. Particularly, what is the save method meant to be doing?

Regards

OK. I think I got that :wink: You want to inject a header into a document.

In this case, you are trying to modify the underlying binary file directly. This breaks the concurrency model completely. Also, you are restricting users of your modified system from choosing the content store they wish to use. You are forcing everyone onto a single filestore with possible concurrency problems.

You need to

ContentReader

ContentService

TempFileProvider

.doc

FileContentWriter

putContent(ContentReader)

ContentWriter

ContentService

putContent(File)

This is the safe way to do it. Take a look at the PdfBoxContentTransformer and the OpenOfficeContentTransformer for similar examples of manipulating files. Absolutely do not attempt to modify the underlying binaries directly.

Get a temporary file using TempFileProvider. Make sure that you give the .doc extension.
Create a FileContentWriter on top of the temp file.

TempFileProvider is just a convenience. If you just create a temporary file directly, be sure to delete it safely in the method's finally block.

You can copy the content to the temporary file using reader.getContent(File) as well.

That question is probably best asked on the OO dev forums.
