[JNDI/Naming/Network] - Re: ClassCastException with proxy

by jaikiran

Post the code where you are doing the lookup and casting. Also have a look at http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassCastExceptions, specifically the jmx-console method mentioned over there.

by thepriz

Yes, that helps a lot. It may explain why I was seeing some problems. I will have to experiment more. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4057201#4057201 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4057201

[EJB/JBoss] - Calling native C++ legacy program from Message Driven Bean

by waikhom

Hi, Could you please help me out on this problem: I am having a C++ program which does mathematical calculation and whan to reuse it in my JEE application. I thought of using MDB and call this C++ code using JNI. Does JBoss support calling native programs using JNI? I heard that using JNI call from EJB is not supported by specification. I also thought of keeping the C++ code as stand alone application by writing a C++ daemon program which will listen to message queue and process the request and send the response back to my J2EE env. This sounds interesting but since this is not in a container, there are many issues like fault tolerance and clustering of this C++ code in production env. If I can direct call this C++ code using JNI.. I can deploy it on production with all the advantages of having JBoss server. Please help me out on this issue. Thanks, Waikhom View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4057200#4057200 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4057200

[JBoss Seam] - Atomic Conversation with <s:link /> tag

by superfis

Hi, I'd like to ask you if it's possible to mark conversation as an Atomic Conversation with <s:link/> or <s:button/>? We've got already: - @Begin(flushMode=MANUAL) - <begin-conversation flush-mode="MANUAL"/> - em.setFlushMode(FlushModeType.COMMIT) but I've noticed that it seems to be not possible to do such a conversation with mentioned tags. Any advice is welcome.

[Persistence, JBoss/CMP, Hibernate, Database] - How to catch Entity Manager exceptions ?

by slugounet

Hi ! I have a few entity beans with validation annotations, and I'd like to be able to catch the exceptions thrown by the hibernate validator when something goes wrong. | @Entity | public class Country { | | @Id | @GeneratedValue( strategy=GenerationType.AUTO ) | private Integer id; | | @NotNull | @Length(min = 1, max = 255) | private String name; | } | | @Stateless | @Remote(Update.class) | public class UpdateSessionBean implements Serializable, Update { | public CountryDataBean updateCountry( CountryDataBean bean ) | throws UpdateException { | Country entity = this.entityManager.find( Country.class, bean.getId() ); | if ( entity == null ) { | throw new UpdateException( "Country not found" ); | } | | CountryMapper mapper = new CountryMapper(); | mapper.toEntity( bean, entity ); | | try { | entity = this.entityManager.merge( entity ); | } | catch( InvalidStateException e ) { | ... do some stuff | } | | mapper.toDataBean( entity, bean ); | return bean; | } | } | When I force an error, I get that kind of error message : | 19:49:43,158 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator_2] TwoPhaseCoordinator.beforeCompletion - failed for com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple@7cd469 | javax.persistence.PersistenceException: org.hibernate.validator.InvalidStateException: validation failed for: prixmac.indexation.database.Country | at org.hibernate.ejb.AbstractEntityManagerImpl$1.beforeCompletion(AbstractEntityManagerImpl.java:527) | at com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple.beforeCompletion(SynchronizationImple.java:114) | at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.beforeCompletion(TwoPhaseCoordinator.java:249) | at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.end(TwoPhaseCoordinator.java:88) | at com.arjuna.ats.arjuna.AtomicAction.commit(AtomicAction.java:177) | at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commitAndDisassociate(TransactionImple.java:1256) | at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.commit(BaseTransaction.java:135) | at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.commit(BaseTransactionManagerDelegate.java:87) | at org.jboss.aspects.tx.TxPolicy.endTransaction(TxPolicy.java:175) | at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:87) | ... | Does anyone have an idea of how I could catch those damned exceptions in my session bean ? Cause it's pretty pointless for me to validate the data if I can't find a way to know that something went wrong :( I'm using JBoss 4.2.0 !
