Hi, Sorry if someone has already asked this ... I am having a problem extending EntityHome with EJB3 SFSBs. So, basically, I have a interface to define the methods I want to use in EntityHome: | public interface PersonDaoInt { | EntityManager getEntityManager(); | Object getId(); | String persist (); | String update (); | String remove (); | public void destroy (); | } | Then, the bean method is like the following: | @Stateful | @Name("personDao") | public class PersonDao extends EntityHome <Person> | implements PersonDaoInt { | | // Configure the entity manager | @PersistenceContext (type=EXTENDED) | private EntityManager em; | | public EntityManager getEntityManager () { | return em; | } | | // Configure the HTTP GET parameter on the page | @RequestParameter | Long pid; | | public Object getId() { return pid; } | | // SFSB requirement | @Remove @Destroy | public void destroy () { } | } | But at deployment time (JBoss 4.0.5 GA), EJB3 complains the following. Does it mean the "remove()" is no longer allowed in EJB3 SFSBs? | java.lang.IllegalArgumentException: methods with same signature remove() but incompatible return types: void and others | at sun.misc.ProxyGenerator.checkReturnTypes(ProxyGenerator.java:610) | at sun.misc.ProxyGenerator.generateClassFile(ProxyGenerator.java:420) | at sun.misc.ProxyGenerator.generateProxyClass(ProxyGenerator.java:306) | at java.lang.reflect.Proxy.getProxyClass(Proxy.java:501) | at org.jboss.ejb3.stateful.BaseStatefulProxyFactory.init(BaseStatefulProxyFactory.java:58) | at org.jboss.ejb3.stateful.BaseStatefulProxyFactory.start(BaseStatefulProxyFactory.java:66) | at org.jboss.ejb3.stateful.StatefulLocalProxyFactory.start(StatefulLocalProxyFactory.java:61) | at org.jboss.ejb3.ProxyDeployer.start(ProxyDeployer.java:105) | at org.jboss.ejb3.SessionContainer.start(SessionContainer.java:124) | at org.jboss.ejb3.stateful.StatefulContainer.start(StatefulContainer.java:91) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.ejb3.ServiceDelegateWrapper.startService(ServiceDelegateWrapper.java:102) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) | at sun.reflect.GeneratedMethodAccessor3.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.system.ServiceController$ServiceProxy.invoke(ServiceController.java:978) | at $Proxy0.start(Unknown Source) | at org.jboss.system.ServiceController.start(ServiceController.java:417) | at sun.reflect.GeneratedMethodAccessor6.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) | at $Proxy54.start(Unknown Source) | at org.jboss.ejb3.JmxKernelAbstraction.install(JmxKernelAbstraction.java:96) | at org.jboss.ejb3.Ejb3Deployment.registerEJBContainer(Ejb3Deployment.java:281) | at org.jboss.ejb3.Ejb3Deployment.start(Ejb3Deployment.java:328) | at org.jboss.ejb3.Ejb3Module.startService(Ejb3Module.java:91) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) | at sun.reflect.GeneratedMethodAccessor3.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | ... ... | Anyone know what's going on?
