- Customer 1: XML over FTP
- Customer 2: CSV over HTTP
- Customer 3: Excel via e-mail

Now on the Acme side, all this has to be converted to a canonical XML format and submitted to the Acme accounting system via JMS. Then the Acme accounting system sends an XML reply via JMS, with a summary of what it processed (e.g. 3 line items accepted, line item #2 in error, total invoice $123.45). Finally, that data needs to be formatted into an e-mail, and sent to a contact at the customer in question ("Dear Joyce, we received an invoice on 1/2/08. We accepted 3 line items totaling $123.45, though there was an error with line items #2 \[invalid quantity ordered\]. Thank you for your business. Love, Acme."). |
So it turns out Camel can handle all this:
- Listen for HTTP, e-mail, and FTP files
- Grab attachments from the e-mail messages
- Convert XML, XLS, and CSV files to a canonical XML format
- using XSLT, automatic data format conversion, and/or POJOs that write to JAXB objects
- read and write JMS messages
- route based on company ID
- format e-mails using Velocity templates
- send outgoing e-mail messages
This tutorial will cover all that, plus setting up tests along the way.
