Thanks Claus, we are currently not using spring directly in this application, so we don't have a spring.xml file explicitly defined, so I'm not sure if this will be an issue with our EJBs if we set up a different transaction manager.
I was also tried to see if I could set up 2 different persistence units, one with the transactions set to "JTA", which the EJBs could use, and the other persistence unit set to RESOURCE_LOCAL, which the Camel JPA component could use, but issue still exists in that case. Surely there must be others out there who are using the JPA component in an application that uses EJBs, but I've found very little in my google searches related to running an app with this configuration. Is there anywhere you could point me to for seeing what it would take to implement this in Java? We are using Camel 2.15 Thanks for your suggestions. -Rob ________________________________________ From: Claus Ibsen <claus.ib...@gmail.com> Sent: Friday, April 17, 2015 10:29 PM To: users@camel.apache.org Subject: Re: Using JPA component in EJB application and having issues with null TransactionManager. 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?
