Description

It would be nice, if the camel-velocity component also read templates from the exchange In message header or attachment. We could define this with following uri's (like in the camel-mina component):

velocity://header:templateHeaderName respectively velocity:header:templateHeaderName

and

velocity://attachment:templateAttachmentName respectively velocity:attachment:templateAttachmentName

I need this flexibility in a project, because the template, which we have to use, must be calculated at runtime and depends on some attributes of the message In body like:

• Which event has triggered this exchange?
• Which customer will receive this message?
• Which protocol is used (smtp, smpp, xmpp, ...)?

I add a more technical description of my requirements in form of four unit tests (see camel-velocity-tests.patch).

The second attachment (camel-velocity.patch) contains the patch, which I have developed to fulfill my requirements. I hope with this contribution, I can make camel a little bit better, than this great framework is already.

Regards,
Christian
