Creating a JCR Client Temp Attachments Provider
The JCR Client Temp Attachments Provider enables you to move or copy files into a designated folder in the My webMethods Server Administrator view. This provider creates an empty temporary folder to store uploaded files, and then deletes the folder when it is no longer used, typically when the managed bean goes out of scope. If the uploaded files are not copied or moved to the target folder, they are also deleted.
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.
