Proxied EJBs as Injection point, wrong interface chosen ------------------------------------------------------- Key: WELD-381 URL: https://jira.jboss.org/jira/browse/WELD-381 Project: Weld Issue Type: Bug Components: Resolution (Typesafe and by Name) Affects Versions: 1.0.0.GA Environment: GF v3, JDK 1.6, Windows Reporter: John Ament Based on the forum post, The following EJB cannot be injected into clients: @DAO @Local(ResultDAOBean.class) @Stateless public ResultDAO extends AbstractDAO<Result> implements ResultDAOBean Happens the same with/without @Local The problem comes in when AbstractDAO implements something (e.g. AbstractDAOBean<E>) or ResultDAOBean extends an interfacet (e.g.AbstractDAOBean<E>). The interface AbstractDAOBean isn't marked as an EJB itnerface, and only one of these two would implement/extend it (ideally, ResultDAOBean). The injection point results in the following exception: Caused by: java.lang.IllegalStateException: Unable to convert ejbRef for ejb ResultDAO to a business object of type interface AbstractDAOBean at com.sun.ejb.containers.EjbContainerServicesImpl.getBusinessObject(EjbContainerServicesImpl.java:104) at org.glassfish.weld.ejb.SessionObjectReferenceImpl.getBusinessObject(SessionObjectReferenceImpl.java:60) at org.jboss.weld.bean.proxy.EnterpriseBeanProxyMethodHandler.invoke(EnterpriseBeanProxyMethodHandler.java:121) at jpa.dao.EvaluationDAOBean_$$_javassist_110.getEM(EvaluationDAOBean_$$_javassist_110.java) at NewSessionBean.init(NewSessionBean.java:30) 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:597) at com.sun.ejb.containers.interceptors.BeanCallbackInterceptor.intercept(InterceptorManager.java:1006) at com.sun.ejb.containers.interceptors.CallbackChainImpl.invokeNext(CallbackChainImpl.java:61) at com.sun.ejb.containers.interceptors.CallbackInvocationContext.proceed(CallbackInvocationContext.java:109) at com.sun.ejb.containers.interceptors.SystemInterceptorProxy.doCallback(SystemInterceptorProxy.java:133) at com.sun.ejb.containers.interceptors.SystemInterceptorProxy.init(SystemInterceptorProxy.java:115) 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:597) at com.sun.ejb.containers.interceptors.CallbackInterceptor.intercept(InterceptorManager.java:961) at com.sun.ejb.containers.interceptors.CallbackChainImpl.invokeNext(CallbackChainImpl.java:61) at com.sun.ejb.containers.interceptors.InterceptorManager.intercept(InterceptorManager.java:390) at com.sun.ejb.containers.interceptors.InterceptorManager.intercept(InterceptorManager.java:373) at com.sun.ejb.containers.AbstractSingletonContainer.createSingletonEJB(AbstractSingletonContainer.java:518) ... 38 more -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
