Spring Exception: The matching wildcard is strict, but no declaration can be found for element 'int-jpa:inbound-channel-adapter' - spring

Question

I have the following spring-config xml file, which is generating the exception shown in the title of my post:

The code I provide above has other elements removed from it, and some of the fields renamed to simplify the example. That is why you see some schema and namespace information at the top that does not apply to the example as presented.
The error actually takes place at the line corresponding to entity-class="foo.Request">, but I don't know that there is anything inherently wrong with that line, but simply that is where the termination ">" is. In other words, if I removed that line and put the ">" after delete-after-poll="false", the error would be there instead.
Am I perhaps missing a namespace and/or schema location definition? Alternatively, could it be a missing deployment dependency? Grateful for any ideas. Thank you.

Please add org.springframework.integration:spring-integration-jpa to your dependencies. You simply missing a jar in your classpath
