[jboss-user] [JBoss Seam] - Re: Design question with Rich GWT Ajax Client
I have a working solution
in my ContextualHttpRequest, I call the same code as in SeamPhaseListener for
JSF.
before proceeding the request :
anonymous wrote :
|void begin()
|{
| try
| {
| if ( !Transaction.instance().isActiveOrMarkedRollback() )
| {
| //log.debug("beginning transaction prior to phase: " +
phaseId);
| Transaction.instance().begin();
| }
| }
| catch (Exception e)
| {
| throw new IllegalStateException("Could not start transaction",
e);
| }
|}
|
at the end :
anonymous wrote :
|void commitOrRollback()
|{
| try
| {
| if ( Transaction.instance().isActive() )
| {
| //log.debug("committing transaction after phase: " +
phaseId);
| Transaction.instance().commit();
| }
| else if (
Transaction.instance().isRolledBackOrMarkedRollback() )
| {
| //log.debug("rolling back transaction after phase: " +
phaseId);
| Transaction.instance().rollback();
| }
| }
| catch (Exception e)
| {
| throw new IllegalStateException("Could not commit
transaction", e);
| }
|}
|
|
I'm sure there are issue with this solution but it works for the begining ...

It seems that SeamPhaseListener does lots of stuff for transaction on the with JSF. When the entitymanager is injected on my SessionBean. If we are on a JSF request the entityManager look like : anonymous wrote : | em = EntityManagerProxy | em.delegate = EmtityManagerImpl | | em.delegate.tx = TransactionImpl | em.delegate.tx.tx = JDBCTransaction | However, if a receive a request an create a ContextualHttpRequest on my custom servlet, the injected entityManager looks like : anonymous wrote : | em = EntityManagerProxy | em.delegate = EmtityManagerImpl | | em.delegate.tx = TransactionImpl | em.delegate.tx.tx = null | The underlying transaction is null ! Think that info can be usefull.

I tried on the same application using the same config and the same EJB's. t works as expected when using JSF. However, when I do the same from my "hand made" Servlet using either ContextualHttpRequest or manualy start Seam context as in the SoapHandler It Does not work and I have the above exception.

[jboss-user] [JBoss Seam] - Re: Design question with Rich GWT Ajax Client
Actually, I have the following problem when I try to use
ContextHttpServletRequest or write the same code as in SOAPRequestHandler in my
Servlet (which parses the JSON mesage and call the Seam component).
I'm working with Seam Manager Persistence Context and Seam Managed Transaction.
I therefore use @In EntityManager em;
here is the code of my SFSB :
|
| import java.util.Collection;
|
| import javax.ejb.Remove;
| import javax.ejb.Stateful;
| import javax.persistence.EntityManager;
|
| import org.jboss.seam.annotations.Begin;
| import org.jboss.seam.annotations.End;
| import org.jboss.seam.annotations.FlushModeType;
| import org.jboss.seam.annotations.In;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.core.Manager;
| import org.jboss.seam.log.Log;
|
| @Stateful
| @Name("SprintaService")
| public class SprintaServiceBean implements SprintaService {
|
| @Logger
| private Log log;
|
| @In EntityManager em;
|
| @Begin(join =true,flushMode = FlushModeType.MANUAL)
| public void begin () {
| this.log.info("Begin Conversation id : " +
Manager.instance().getCurrentConversationId());
| }
|
| public Person createPerson(Person person) {
| this.log.info("Continuing Conversation id : " +
Manager.instance().getCurrentConversationId());
| this.em.persist(person);
| return person;
| }
|
|
| @End
| public void end() {
| this.log.info("Ending Conversation id : " +
Manager.instance().getCurrentConversationId());
| this.em.flush();
| }
|
| @Remove
| public void remove () {
|
| }
|
| }
|
If I call the "createPerson" only, it works and commits the transaction.
If I call the begin method then the createPerson, I have an Exception, but,
after the Servlet complete.
Here is the exception :

Can I put the conversation id into the JSON Message and, in that case, do the
same logic as in "SOAPRequestHandler" then without wrapping my code in
ContextHttpServletRequest which need the request param ?
What SOAPRequestHandler does for each request is :
|
| ServletLifecycle.beginRequest(request);
|
| ServletContexts.instance().setRequest(request);
|
| String conversationId = //I extract my cid here
| ConversationPropagation.instance().setConversationId(
conversationId );
| Manager.instance().restoreConversation();
|
| ServletLifecycle.resumeConversation(request);
and after the request completion :
| String conversationId =
Manager.instance().getCurrentConversationId();
| if (conversationId != null)
| {
| //put the cid in my JSON response
| }
| Manager.instance().endRequest( new
ServletRequestSessionMap(request) );
Is that enough to use the Seam-managed persistence context and Seam managed
transaction ?
Tks

[jboss-user] [JBoss Seam] - Re: Design question with Rich GWT Ajax Client
Those examples are very interesting, However, in my case, I'm not using GWT's RCP mechanism but simply JSON over HTTP. So, let's say, I have a Controller Servlet handling request and calling different session bean depending on the content of the message. there is where I don't know how to integrate Seam in the business.
