JPA Component
The jpa: component allows you to work with databases using JPA (EJB 3 Persistence) such as for working with OpenJPA, Hibernate, TopLink to work with relational databases.
Sending to the endpoint
Sending POJOs to the JPA endpoint inserts entities into the database. The body of the message is assumed to be an entity bean (i.e. a POJO with an @Entity annotation on it).
If the body does not contain an entity bean then use a Message Translater in front of the endpoint to perform the necessary conversion first.
Consuming from the endpoint
Consuming messages removes (or updates) entities in the database. This allows you to use a database table as a logical queue, consumerse take messages from the queue and then delete/update them to logically remove them from the queue.
URI format
jpa:[entityClassName]
For sending to the endpoint, the entityClassName is optional. If specified it is used to help use the Type Conversion to ensure the body is of the correct type.
For consuming the entityClassName is mandatory.
