Creating a JCR Sub-Folder Attachments Provider
The JCR Client Sub-Folder Attachments Provider enables you to create a sub-folder in the My webMethods Server Administrator view that you can use to open, add, delete, or modify files.
This provider can be used to submit a document to start a business, to upload a document to My webMethods Server, create a unique folder for the process, and pass the folder as business data for the process. Tasks can then use the document as an attachment.
You must enable the JCR client for your CAF application before you can use a JCR provider. For more information, see Enabling the JCR Client for a CAF Application.
When you create the Sub-Folder Attachments Provider, Composite Application Framework performs the following:
