i am trying to write an entity to database with camel jpa component. The
problem is that i get
javax.persistence.TransactionRequiredException: no transaction is in
progress
at
org.hibernate.internal.SessionImpl.checkTransactionNeeded(SessionImpl.java:3428)
at org.hibernate.internal.SessionImpl.doFlush(SessionImpl.java:1395)
at org.hibernate.internal.SessionImpl.flush(SessionImpl.java:1391)
at
org.apache.camel.component.jpa.JpaProducer$1.doInTransaction(JpaProducer.java:85)
The persistent unit is parsed fin and the table is created. Here ist
persistence.xml:
I created a test to write one entity:
Since there is no real way to start and end a transaction in camel semantic
i think the problem is related to setup?
I also tried to add ``.transacted()`` to the route. This yields ``No bean
could be found in the registry of type: PlatformTransactionManager``
Then i added this line to setup method:
and this again yields ``javax.persistence.TransactionRequiredException: no
transaction is in progress``.
i am not sure what to configure on JpaComponent and what to bind into the
registry.
I also debugged a bit. I checked the fields in JpaProducer where
``entityManager.flush()`` is throwing the exception:
trasactionTemplate is set "PRPAGATION_REQUIRED,ISOLATION_DEFAULT" with
correct JpaTransactionManager.
So how to get JPA-component working?
(my code is based on this:
