entityType

entityClassName

Overrides the entityClassName from the URI.

persistenceUnit

camel

The JPA persistence unit used by default.

consumeDelete

true

JPA consumer only: If true, the entity is deleted after it is consumed; if false, the entity is not deleted.

consumeLockEntity

true

JPA consumer only: Specifies whether or not to set an exclusive lock on each entity bean while processing the results from polling.

flushOnSend

true

JPA producer only: Flushes the EntityManager after the entity bean has been persisted.

maximumResults

-1

JPA consumer only: Set the maximum number of results to retrieve on the Query.

transactionManager

null

Camel 1.6.1/2.0: Specifies the transaction manager to use. If none provided, Camel will use a JpaTransactionManager by default. Can be used to set a JTA transaction manager (for integration with an EJB container).

consumer.delay

500

JPA consumer only: Delay in milliseconds between each poll.

consumer.initialDelay

1000

JPA consumer only: Milliseconds before polling starts.

consumer.useFixedDelay

false

JPA consumer only: Set to true to use fixed delay between polls, otherwise fixed rate is used. See ScheduledExecutorService in JDK for details.

maxMessagesPerPoll

0

Camel 2.0: JPA consumer only: An integer value to define the maximum number of messages to gather per poll. By default, no maximum is set. Can be used to avoid polling many thousands of messages when starting up the server. Set a value of 0 or negative to disable.

consumer.query

JPA consumer only: To use a custom query when consuming data.

consumer.namedQuery

JPA consumer only: To use a named query when consuming data.

consumer.nativeQuery

JPA consumer only: To use a custom native query when consuming data.

usePersist

false

JPA producer only: Indicates to use entityManager.persist(entity) instead of entityManager.merge(entity). Note: entityManager.persist(entity) doesn't work for detached entities (where the EntityManager has to execute an UPDATE instead of an INSERT query)!
