[EJB 3.0 Development] - Stateful beans from 2 Jars - 1 persistence unit

by Nick Dodd

Nick Dodd [http://community.jboss.org/people/baronDodd] created the discussion "Stateful beans from 2 Jars - 1 persistence unit" To view the discussion, visit: http://community.jboss.org/message/537473#537473 -------------------------------------------------------------- I have a persistence unit named FOO inside a jar file as follows: <persistence-unit name="FOO"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:/MYDS</jta-data-source> <properties> <property name="hibernate.hbm2ddl.auto" value="update"/> </properties> <jar-file>file:../anotherDir/secondary.jar</jar-file> </persistence-unit> This jar contains several Entity Beans and Session Beans that use this persistence unit ok. As you can see I also have a second jar referenced in the persistence unit, it is another jar (not within an ear) that contains 1 more Entity bean and also 1 Session Bean. When I start the server +all+ tables are successfully created including the entity defined in the secondary jar. However - the Session Bean in the secondary jar is causing problems. public class SecondaryFacade implements SecondaryFacadeLocal, SecondaryFacadeRemote { ...... @PersistenceContext(unitName="FOO") protected EntityManager em; ...... ObjectName: persistence.units:unitName=FOO State: NOTYETINSTALLED Depends On Me: jboss.j2ee:service=EJB3,jar=secondary.jar,name= SecondaryFacade This issue may be related but not sure: http://community.jboss.org/message/344723#344723 http://community.jboss.org/message/344723#344723 Am running JBoss 4.3.0. What I am doing might not even be possible or legal but if so then why does it deploy the Entity Bean successfully but not the Session Bean? Many thanks -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537473#537473] Start a new discussion in EJB 3.0 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-dev-forums] [JBoss Microcontainer Development] - JBoss Reflect Performance Javassist vs Introspection

Kabir Khan [http://community.jboss.org/people/kabir.khan%40jboss.com] replied to the discussion "JBoss Reflect Performance Javassist vs Introspection" To view the discussion, visit: http://community.jboss.org/message/537449#537449 -------------------------------------------------------------- I've tried starting AS with the two implementations, and the overhead of creating accessor classes means javassist is slower. Javassist: ~24.5s Introspection: ~21s I need to profile this, but think this is because when configuring beans, we normally only set properties once, so we get the overhead of creating the class, but not the benefit of invoking it lots of times. I will ask Chiba if there is anything that can be done to JavassistMembersFactory to make this faster. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537449#537449] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Microcontainer Development] - JBoss Reflect Performance Javassist vs Introspection

by Kabir Khan

Kabir Khan [http://community.jboss.org/people/kabir.khan%40jboss.com] created the discussion "JBoss Reflect Performance Javassist vs Introspection" To view the discussion, visit: http://community.jboss.org/message/537409#537409 -------------------------------------------------------------- I have created a simple benchmark where I test the performance of different things using the different implementations. It can be found at https://svn.jboss.org/repos/jbossas/projects/jboss-reflect/trunk/src/test... https://svn.jboss.org/repos/jbossas/projects/jboss-reflect/trunk/src/test... It first generates 100 classes, each with 100 fields and 100 methods, then it: * A) Obtains a ClassInfo for each class * B) Goes through each class and calls getDeclaredField() and getDeclaredMethod() for each field/method. This is done 50 times * C) Calls FieldInfo.get/set and MethodInfo.get/set once for each field/method * D) Same as C, but now it happens 50 times Here are the times: > > ========== IntrospectionTypeInfoFactory > > A - Creating 100 ClassInfos 141ms > > B - Getting 100 fields and methods for 100 classes 50 times 1446ms > > C - First accessing 100 fields and methods for 100 classes 50 times 116ms > > D - Accessing 100 fields and methods for 100 classes 50 times 3545ms > > Done! > > > > > ========== JavassistTypeInfoFactory > > A - Creating 100 ClassInfos 164ms > > B - Getting 100 fields and methods for 100 classes 50 times 820ms > > C - First accessing 100 fields and methods for 100 classes 50 times 4557ms > > D - Accessing 100 fields and methods for 100 classes 50 times 272ms > > Done! > * Creating the ClassInfos (A) takes about the same time with the two implementations. * Calling getDeclaredMethod()/-Field() (B) is about twice as fast using Javassist as introspection. * The first time a joinpoint is invoked is very slow with Javassist (due to generating the class), while subsequent calls are very fast I'll profile C to see if it can be made faster somehow. Although, 20,000 classes are created so my guess is that creating an output stream for the class bytes for each class and then it with the classloader is the real overhead -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537409#537409] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

After all the injections have been carried out, the container must invoke the method carrying a javax.annotation.PostConstruct annotation. The question is the scoping. Should this EJB3 associated JAX-WS handler (part of WS runtime) see environment entries of particular EJB3 bean? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537344#537344] Start a new discussion in EJB 3.0 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

It defines *boolean1* env entry. <ejb-jar> <enterprise-beans> <session> <ejb-name>EJB3Bean</ejb-name> <ejb-class>org.jboss.test.ws.jaxws.ejb3Integration.injection.webservice.EJB3Bean</ejb-class> * <env-entry> <env-entry-name>boolean1</env-entry-name> <env-entry-type>java.lang.Boolean</env-entry-type> <env-entry-value>true</env-entry-value> </env-entry>* </session> </enterprise-beans> </ejb-jar> There's a handler associated with this EJB3Bean @WebService *@HandlerChain(file = "jaxws-handler.xml") *@Stateless public class EJB3Bean extends AbstractEndpointImpl { public String echo(String msg) { return super.echo(msg) + ":EJB3Bean"; } } The content of jaxws-handler.xml is: <handler-chains> <handler-chain> <handler> <handler-name>TestHandler</handler-name> * <handler-class>org.jboss.test.ws.jaxws.ejb3Integration.injection.shared.handlers.TestHandler</handler-class> * </handler> </handler-chain> </handler-chains> This TestHandler tries to access both EJB3Bean and it's env-entry public final class TestHandler extends GenericSOAPHandler { * @Resource private Boolean boolean1; @EJB private BeanIface bean1;* ... }** Using global JNDI I'm able to fix @EJB injection. *Question for EJB3 team:* Do you think this JAX-WS handler should see env-entry of EJB3Bean? That would mean required access to EJB3Bean specific JNDI context (the reason why we're using it instead of global JNDI). I'll double check JAX-WS and EE6 specification for clarification, but would like to know your opinion ;) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537334#537334] Start a new discussion in EJB 3.0 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
