Container-Managed EM on TomEE+ with OpenJPA
Hi all,
I've set up a small hands-on webapp with one JPA entity and one REST
service. Database gets created on TomEE startup and app is successfully
deployed and reachable.
Although this should be quite straightforward, I still have two problems
with this:
1.) The OpenJPA user's guide says here
<http://openjpa.apache.org/docs/openjpa-0.9.0-incubating/manual/manual.html#ref_guide_mapping_synch>
that the mapping gets done when the application obtains its first EM. This
is somehow not working for me -- not until I make some random call on the
injected entity manager (see method getEntityManagerProperties in
HelloRest.java).
2.) After the first call on the EM and the creation of the table for
HelloEntity, one might think that everything is set now to stick some rows
in ... but this fails because there is no active transaction when calling
em.persist(). As of my understanding, the lifecycle of the EM should be
managed by the container, so I should't need to hassle with any
EntityManagerFactory, Transactions and soon.
Any thoughts on what could cause this weird behaviour?
Attached below is all that's involved:
*tomee.xml*
<tomee>
<Resource id="test_ds" type="DataSource">
JdbcDriver org.apache.derby.jdbc.ClientDriver
JdbcUrl jdbc:derby://localhost:1527/test_db;create=true
UserName user
Password password
JtaManaged true
InitialSize 5
</Resource>
</tomee>
BTW, the database gets created only if I set the resource's InitialSize
property to a value > 0
Maybe this way I'm forcing a database connection and that's the only reason
I get at least the database created.
*persistence.xml*
<persistence ...>
<persistence-unit name="test_pu" transaction-type="JTA">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>test_ds</jta-data-source>
<non-jta-data-source>test_ds_unmanaged</non-jta-data-source>
<class>de.mdesign.hellorest.entity.HelloEntity</class>
<properties>
<property name="openjpa.jdbc.SynchronizeMappings"
value="buildSchema(ForeignKeys=true)"/>
</properties>
</persistence-unit>
</persistence>
*Entity*
@Entity
public class HelloEntity implements Serializable {
@Id
@GeneratedValue
private Long id;
@Column
private String name;
...
}
*App*
@Path("/HelloRest")
@Produces({MediaType.TEXT_PLAIN})
public class HelloRest {
@PersistenceContext(unitName = "test_pu")
private EntityManager em;
@GET
@Path("/props")
public String getEntityManagerProperties() {
Map<String, Object> emProps = em.getProperties(); // INVOKES THE
MAPPING TOOL
String ret = "";
for(String key : emProps.keySet()) ret += key+" =
"+emProps.get(key)+"\n";
return ret;
}
@PUT
@Path("/create")
public String createEntry(@QueryParam("name") String name) {
HelloEntity hello = new HelloEntity();
hello.setName(name);
em.persist(hello); // FAILS WITH TransactionRequiredException
return ("Hello "+hello.getName()+" (id="+hello.getId()+")");
}
}
*Here's the trace of the persist failure:*

Posted by Romain Manni-Bucau <rm...@gmail.com>.
About init we have a priperty to force it at startup (you can inspire your
persistence.xml from
https://github.com/rmannibucau/JeBlog/blob/master/src/main/webapp/WEB-INF/persistence.xml
)
About transaction...you need an ejb. Just add @Stateless on your rest
endpoint for instance.
About initial size you are right, i think it is fixed on trunk. Was an
error between dbcp and tomcat-jdbc config implicit conversion IIRC.

Re: Container-Managed EM on TomEE+ with OpenJPA
Posted by Witold Szczerba <pl...@gmail.com>.
Hi,
Your JAX-RS bean is not transaction aware, because you did not make it an
EJB. Add @Stateless to it. As of now, it is nothing but a kind of Servlet
decorator.
Another option would be to move the database and EM related stuff to other
EJB and call it from within your JAX-RS bean, but I would not recommend
this, because the transaction boundary will be misplaced, IMHO. Calling
second EJB from such an endpoint (within one method) would create second
transaction. In case of rollback, your endpoint would cause someting to be
committed and something to be rolled back.
Also, when your JAX-RS is transaction aware, you can inject stuff which
does not have to be EJB, because it will participate under transaction
umbrella of your endpoint.
Regards,
Witold Szczerba
