I suppose you could persist it as a byte[], jBPM will persist them, but there will likely be issues with a blob that big (talking on pure assumption here). The alternative is to store some reference to your document in the process, and reference it when you need to with a link or some such assuming you have some PK to the external system (or your system) where the document is actually stored.
