Not able to use seam persistence

[mmrath]

I have a web app running in jetty fine with some code for creating persistence context manually. I added few lines of code to use seam-persistence.

1. My beans.xml looks as below

<beans xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:s="urn:java:ee"
   xmlns:t="urn:java:org.jboss.seam.persistence.transaction"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
   http://docs.jboss.org/cdi/beans_1_0.xsd">
    <interceptors>
        <class>org.jboss.seam.persistence.transaction.TransactionInterceptor</class>
    </interceptors>

    <t:SeSynchronizations>
        <s:modifies/>
    </t:SeSynchronizations>

    <t:EntityTransaction>
        <s:modifies />
    </t:EntityTransaction>
</beans>



2. Added the following to POM


        <dependency>
            <groupId>org.jboss.seam.persistence</groupId>
            <artifactId>seam-persistence</artifactId>
            <version>3.0.0.Beta2</version>
        </dependency>
        <dependency>
            <groupId>org.jboss.seam.config</groupId>
            <artifactId>seam-config-xml</artifactId>
            <version>3.0.0.Beta2</version>
            <scope>runtime</scope>
        </dependency>


3. created the following code. Not sure if this is correct


public class PersistenceContextProvider {

    @SeamManaged
    @Produces
    @PersistenceUnit
    @ConversationScoped
    EntityManagerFactory producerField;

}


4. injecting em as below

    @Inject
    private EntityManager entityManager;




I am getting the following exception

Hopefully Shane can comment on this, but it's looking to me like this is a problem because you're in Jetty 6/7 and you don't have the EJB APIs, probably because you're using @PersistenceContext.  I haven't tried running outside of a Java EE 6 container, so I'm honestly not sure if I'm telling you correctly or not.  Try adding the jars, or look for an embedded EJB3.1 container and give that a shot.

[shane.bryzak]

What Jason says sounds right, however I'm a Jetty noob so probably Stuart would be the best person to answer this question.  I'll see if he can take a quick look at this.

What version of weld are you running? Older versions of weld would die if they encountered a NoClassDefFoundException while scanning.

I have another issue. We run jboss AS 6 with weld. Now I am adding seam 3 persistence module (SMPC) as we see the limitation of Entended persistence context type in SFSB.
I also heard that with seam 3 persistence module, we do not even have to use a EJB to have transaction, a simple annotaion @TransactionAttribute will do the trick. But I tried it out with 

<interceptors>        <class>org.jboss.seam.persistence.transaction.TransactionInterceptor</class></interceptors>

turned on in beans.xml (beans.xml is under WEB-INF). But it does not seem to work. I got no transaction error when I create an entity. But if I annotation the bean with @Stateless or @Stateful, along with @TransactionAttribute, then the entity can be created into database.

Anybody in this forum can enlighten me? Is that still true that we do not need ejb to use SMPC?

[swd847]

Can you post some more details?
- The code for the class that you are annotating
- Where is this class (WEB-INF/classes?)
- Which container are you using?

[yangju.richard.yang.pearson.com]

See the code snippet:


@TransactionAttribute
public class TestServiceImpl implements TestService {

    @Inject
    private TestDAO testDAO;

    @Inject
    @TestDBRepo
    @PersistenceContext
    private EntityManager testEm;

    @Inject
    @Updated
   

`Event<TestUser> userEvent;`



    @Inject
    private Logger log;

    public TestServiceImpl() {

    }

//producer class
public class TestDBRepoProducer {
    @TestDBRepo
    @SeamManaged
    @ConversationScoped
    @Produces
    @PersistenceUnit(unitName = "testPU")
    EntityManagerFactory emf;
}


    @PostConstruct
    private void setEm() {
        testDAO.setEm(testEm);
    }

    @Override
    public TestUser getByUserById(int id) {
        return testDAO.findById(id);
    }

}

[yangju.richard.yang.pearson.com]

Also, I run the webapp under jboss AS 6 Final.

I also tried seam 3 security module (alpha1). It did not work with the rest of the modulesv(got deployment error) as it still depends on weld-extension while other modules depend on solder.
