I have a problem with starting a jpa bundle inside ServiceMix. The problem occurs when using EntityManager injection, while injection of an EntityManagerFactory works fine. Any idea what's wrong?
My persistence.xml:

Deploying the bundle fails with the following exception:

I have some classes (ejb, webservices, mdb, etc..) that can use JTA. For some classes I need RESOURCE_LOCAL (can't be injected). However I can't get tomee to reference the jndi name of RESOURCE_LOCAL. How do you setup tomee and RESOURCE_LOCAL? I can't seem to find one good example online, I would prefer not to put any usernames and passwords in my persistence.xml file.
tomee.xml has this:
<Resource id="MYDS" type="DataSource">
JdbcDriver com.mysql.jdbc.Driver
JdbcUrl jdbc:mysql://127.0.0.1:3306/maestro
UserName myusername
Password mypassword
JtaManaged false
</Resource>
persistence.xml looks like:

</persistence>
I am using name MYDS in EntityManagerFactory lookup, but get this error:

the solution seems to be this (still verifying):
(not very intuative or documented, adding openejb:Resource to JPA and JPA doesn't work, removing it from RESOURCE_LOCAL and RESOURCE_LOCAL doesn't work)

how do you get your persistence unit? Manually?
If using injection:
#PersistenceUnit EntityManagerFactory emf;
#PersistenceContect EntityManager em;
TomEE resolves the datasource for you from its short name (id in tomee.xml) otherwise you need to give it the full JNDI name which I think is java:openejb/Resource/MYDS
I have an application based on Apache Camel that runs on JBoss AS 7.1 application server.
In one Camel route, I let Camel read XML files, unmarshal them to JPA entity objects using JAXB, and write them to a database using the Camel jpa:// component.
However, whenever an entity is sent to a JPA endpoint, Camel gives me the following TransactionRequiredException:
javax.persistence.TransactionRequiredException: joinTransaction has been called on a resource-local EntityManager which is unable to register for a JTA transaction.

What I don't understand is that JPA insists that my EntityManager is resource-local. In my persistence.xml, I've defined the data source as JTA:
persistence.xml:

<property name="eclipselink.logging.parameters" value="true"/>
</properties>
</persistence-unit>
</persistence>
The relevant section in my applicationContext.xml is this:
<!-- snip -->

If my research online was thorough, then all this is supposed to be correct and transaction management should work.
However, it doesn't.
What am I doing wrong?
The package versions I'm using:
Camel 2.14.3
Spring 4.1.6.RELEASE
Eclipselink 2.6.0-M3
JBoss AS 7.1.1-Final
Thanks in advance to everyone!
This exception usually occurs when you do not start a transaction. Remember transaction needs to be started at service level not at repository level. As service and repository code is not available here cannot help more.
I can not build my entity manager factory and the error I get is "chosen transaction strategy requires access to the JTA Transaction Manager". Can anyone advise what i have to configure to get past this? FYI I'm using Jboss 6, no spring.

Here is an non ideal answer which I will use in the meanwhile.
specify a non jta datasource:
<non-jta-data-source>java:/jdbc/thor_ds</non-jta-data-source>
change transaction type from JTA to RESOURCE_LOCAL
<persistence-unit name="AvengersPU" transaction-type="RESOURCE_LOCAL">

Try sending in an application request. I don't think synchronize mappings is triggered until the first EntityManager is created.
We've been working on this for days and we are stumped. This is supposed to be an easy tutortial using TopLink. We are trying to get this to work before we do our real web app. This is the following exception we get:
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named pu1:
The following providers:
oracle.toplink.essentials.PersistenceProvider
oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider
Returned null to createEntityManagerFactory.
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:154)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83)
at client.Client.main(Client.java:45)
Java Result: 1
this happens after executing this line from our emf driver class:
emf = Persistence.createEntityManagerFactory("pu1");
I'm assuming the problem is in our persistence.xml file (which is in the correct folder (WEB-INF/classes/META-INF). Also netbeans generated the xml file for us which is:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="JPAExamplePU" transaction-type="JTA">
<provider>oracle.toplink.essentials.PersistenceProvider</provider>
<jta-data-source>SomeDB</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="toplink.ddl-generation" value="drop-and-create-tables"/>
</properties>
</persistence-unit>
</persistence>
We were also thinking it may be an adding a library issue or something along that line. Any help is much appreciated. Thanks
You have the wrong persistence unit name. Use the one from the xml (i.e. the one defined with <persistence-unit name="..."):
emf = Persistence.createEntityManagerFactory("JPAExamplePU");
