> Hi,
> I have found a problem regarding a wiretap and the camel-jpa component. I
> have a route with an async split through a wiretap. In each route, I use a
> jpa producer to persist an entity. The problem is, that the entitymanager was
> closed before the async routes can reach the end. The cause is, that the same
> entitymanager is used in the async routes. The main route reaches the end and
> closes the entitymanager.
> E.g. like the following route:
> {code}
> <route id="mainRoute>
> <from uri="direct:restendpoint"/>
> ...
> <to uri="jpa:MyEntity"/>
> ...
> <loop copy="true">
> ...
> <wireTap uri="direct:asyncroute"/>
> </loop>
> </route>
> <route id="asyncRoute">
> <from uri="direct:asyncroute"/>
> ...
> <to uri="jpa:MyEntity"/>
> ...
> </route>
> {code}
> I think a possible fix can be to check that the entitymanager is null or
> closed. If null or closed, create a new entitymanager.
> {code}
> public final class JpaHelper {
> ...
> public static EntityManager getTargetEntityManager(Exchange exchange, ...
> ...
> if (em == null || !em.isOpen()) {
> // create a new entity manager
> em = entityManagerFactory.createEntityManager();
> ...
> }
> }
> ...
> }
> {code}
> Another solution can be in the wiretap. There where the exchange is copied,
> the "CamelEntityManager" property could be removed.
> Currently, my quickfix is: At the beginning of the async route I remove the
> entitymanager from the exchange.
