Subject Re: Using JPA component in EJB application and having issues with null TransactionManager.
Date Sat, 18 Apr 2015 05:29:33 GMT
Hi

You can likely configure the transaction manager on the jpa component
directly if you use spring xml

<bean id="jpa" class="org.apache.camel.component.jpa.JpaComponent">
   <property name ..."
   .. configure transaction manager here
</bean>

You can also configure this from java code, but that requires a bit
different work.

Maybe that helps?

And btw what version of Camel do you use?

for some new functionality, but I am getting NullPointerExceptions complaining about the transaction
manager when I attempt to run a JPA consumer in the app.  Details are below:
