Re: JPA doc related to EM Producer
Hi, DS doc specifies the use of BeanManagedUserTransactionStrategy in beans.xml. Should'nt that be enough? ..or containermanaged strategy? br hw -- View this message in context: http://apache-deltaspike-incubator-discussions.2316169.n4.nabble.com/JPA-doc-related-to-EM-Producer-tp4658999p4659081.html Sent from the Apache DeltaSpike Incubator Discussions mailing list archive at Nabble.com.
Re: JPA doc related to EM Producer
IIRC with deltaspike you need a custom transaction strategy for JTA (DS is really designed for resource local *by default*) Romain Manni-Bucau Twitter: @rmannibucau Blog: http://rmannibucau.wordpress.com/ LinkedIn: http://fr.linkedin.com/in/rmannibucau Github: https://github.com/rmannibucau 2014-10-03 8:36 GMT+02:00 hwaastad : > Hi, > I've tried but realized an issue when using deltaspike and cdi injection in > custom validators. > > the entity is flushed before validation is run and hence will fail. > > I made a test project on github > (https://github.com/hwaastad/TomeeDsValidation.git) and u'll see that > validation fails if the entitymanager is produced like this. > > br hw > > > > -- > View this message in context: > http://apache-deltaspike-incubator-discussions.2316169.n4.nabble.com/JPA-doc-related-to-EM-Producer-tp4658999p4659079.html > Sent from the Apache DeltaSpike Incubator Discussions mailing list archive at > Nabble.com.
Re: JPA doc related to EM Producer
Hi, I've tried but realized an issue when using deltaspike and cdi injection in custom validators. the entity is flushed before validation is run and hence will fail. I made a test project on github (https://github.com/hwaastad/TomeeDsValidation.git) and u'll see that validation fails if the entitymanager is produced like this. br hw -- View this message in context: http://apache-deltaspike-incubator-discussions.2316169.n4.nabble.com/JPA-doc-related-to-EM-Producer-tp4658999p4659079.html Sent from the Apache DeltaSpike Incubator Discussions mailing list archive at Nabble.com.
Re: JPA doc related to EM Producer
Can you try this?
@PersistenceContext(unitName = APP_NAME)
private EntityManager entityManager;
@Produces
@RequestScoped
protected EntityManager createEntityManager() {
return this.entityManager;
}

Re: JPA doc related to EM Producer
Hi,
maybe a little late on this but I've been testing differet scenarios using
tomee and deltaspike and using JTA these are the ones I found out working:
@Produces
@ApplicationScoped
public EntityManagerFactory createEntityManagerFactory() {
System.out.println("Producing EMF..");
return Persistence.createEntityManagerFactory("ValidationPU");
}
@Produces
public EntityManager createEntityManager(EntityManagerFactory
entityManagerFactory) {
System.out.println("Producing entitymanager.");
return entityManagerFactory.createEntityManager();
}
with a little help from @romain i realized that my em's were resource_local
using the producer shown in the DS docs.

Re: JPA doc related to EM Producer
since we only provide documentation about deltaspike itself, it should be clear implicitly. some modules extend ee6/ee7 and therefore you will see a mix of java ee and deltaspike by definition. (BMT is a valid part of the spec. and therefore nothing special/separated.) regards, gerhard 2014-09-26 14:16 GMT+02:00 Claudio Miranda : > On Thu, Sep 25, 2014 at 7:05 PM, Gerhard Petracek > wrote: > > > > please have a look at [1]. there you can see several differences compared > > to your demo. > > e.g. you don't have the TransactionalInterceptor in your beans.xml (see > > [2]). if you would like to use jta, please have a look at [3]. > > > Hi Gerhard, the demo kitchenskink I did, doesn't use deltaspike, now I > understand the jpa doc is related to the deltaspike @Transactional and > not the JEE7 @Transactional.

Hi Gerhard, the demo kitchenskink I did, doesn't use deltaspike, now I understand the jpa doc is related to the deltaspike @Transactional and not the JEE7 @Transactional. Now it makes sense to use @PersistenceUnit as the @Transactional interceptor needs BMT. Would it make sense to tell in the jpa doc that the @Transactional it refers is the deltaspike and not the JEE7 ? Thanks for your clarification. -- clau...@claudius.com.br http://www.claudius.com.br
Re: JPA doc related to EM Producer
hi claudio, please have a look at [1]. there you can see several differences compared to your demo. e.g. you don't have the TransactionalInterceptor in your beans.xml (see [2]). if you would like to use jta, please have a look at [3]. regards, gerhard [1] https://github.com/jboss-developer/jboss-wfk-quickstarts/blob/2.6.0.Final/kitchensink-deltaspike [2] http://deltaspike.apache.org/documentation/jpa.html#__transactional [3] http://deltaspike.apache.org/documentation/jpa.html#_jta_support 2014-09-24 10:39 GMT+02:00 Gerhard Petracek : > thx for providing the demo-application which illustrates the issue. i'll > have a look at it. > > regards, > gerhard > > > > 2014-09-24 3:51 GMT+02:00 Claudio Miranda : > >> On Mon, Sep 22, 2014 at 5:36 PM, Gerhard Petracek >> wrote: >> > that part of the documentation is based on demo-applications. >> > if something doesn't work for you, please provide a link to >> > a demo-application which illustrates the issue. >> >> See [1] for the demo application that reproduces the issue.

See [1] for the demo application that reproduces the issue. There are two applications based on kitchensink from wildfly quickstarts. kitchensink-em uses the @PersistenceContext and the @Transactional works. kitchensink-emf uses the @PersistenceUnit and the @Transactional doesn't work. To reproduce, build them and deploy to wildfly 8.1, go to the application and register a member, it the persist operation is implemented in the MemberRegistration class. 1. https://www.dropbox.com/s/vid6s7vq2oqnx4g/deltaspike.zip?dl=0 Kind regards -- Claudio Miranda clau...@claudius.com.br http://www.claudius.com.br
Re: JPA doc related to EM Producer
hi claudio, the injected entity-manager is already a proxy -> you can expose it as it is. that part of the documentation is based on demo-applications. if something doesn't work for you, please provide a link to a demo-application which illustrates the issue. regards, gerhard 2014-09-22 22:24 GMT+02:00 Claudio Miranda : > Hi, I was reading the jpa doc [1], and the recommendation to inject > the @PersistenceUnit to create an EM to produce it, the @Transactional > doesn't work, as the EM is BMT, the em.persist doesn't flush the > entity to table. > > Also every emf.createEM invocation will create a new EM, looks like > the right approach to produce an EM for EE server is the no EE-Server > section. > > 1. deltaspike.apache.org/documentation/jpa.html > > -- > Claudio Miranda > > clau...@claudius.com.br > http://www.claudius.com.br >
JPA doc related to EM Producer
Hi, I was reading the jpa doc [1], and the recommendation to inject the @PersistenceUnit to create an EM to produce it, the @Transactional doesn't work, as the EM is BMT, the em.persist doesn't flush the entity to table. Also every emf.createEM invocation will create a new EM, looks like the right approach to produce an EM for EE server is the no EE-Server section. 1. deltaspike.apache.org/documentation/jpa.html -- Claudio Miranda clau...@claudius.com.br http://www.claudius.com.br
