So after a big refactoring project, I am left with this exception and am unsure as how to correct it. It's dealing with some code that I did not write and I am unfamiliar with how it all works. There are other questions out there dealing with this exception, but none seem to fit my situation.
The class which uses EntityManager
is SpecialClaimsCaseRepositoryImpl
:
package com.redacted.sch.repository.jpa;
//Imports
@Repository
public class SpecialClaimsCaseRepositoryImpl extends SimpleJpaRepository<SpecialClaimsCaseDto, SpecialClaimsCaseDto.Id> implements SpecialClaimsCaseRepository{
@PersistenceContext(unitName = "schManager")
private EntityManager em;
//Some autogenerated methods
public void setEntityManager(EntityManager em) {
this.em = em;
}
public EntityManager getEntityManager() {
return em;
}
}

Caused by: java.lang.IllegalStateException: A JTA EntityManager cannot use getTransaction()

I'm a total noob here, so if any other information is needed just ask and I'll update.
Thanks for all the help!
The problem is your configuration. You have hibernate configured for JTA.
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereExtendedJTATransactionLookup" />
Whereas you are using local transactions instead of distributed transactions.
at org.springframework.orm.jpa.JpaTransactionManager.doBegin(JpaTransactionManager.java:380)
You have 2 possible solutions
JpaTransactionManager
and replace it with a JTA transaction managerhibernate.transaction.manager_lookup_class
from the hibernate settings.If you don't really need distributed transactions option 2 is the easiest, if you need distributed transactions simply adding <tx:jta-transaction-manager />
will setup a proper JTA tx manager for your environment. Remove the definition for the JpaTransactionManager
.
Update:
Your configuration is flawed in 2 ways.
<tx:jta-transaction-manager />
and JpaTransactionManager
which one do you want to use? At the moment the latter is overriding the first one.Create 2 seperate configurations one for local testing and one for production using JTA en JNDI lookups. (Preferable your testing code only overrides the beans necessary).
