The error isn't because multiple EJBs are implementing the same interface, but it's because the usage of the @EJB in your application is such that the container has no idea which of the multiple EJB implementations you are trying to setup into the java:global namespace via the @EJB usage: @Stateless @EJB(name = "java:global/coo/TestBean1", beanInterface = TestBean.class) public class TestBean1 implements TestBean{ }   @Stateless @EJB(name = "java:global/coo/TestBean2", beanInterface = TestBean.class) public class TestBean2 implements TestBean{ The spec allows you to narrow it down to the specific EJB implementation. You can do so by using the "beanName" attribute of the @EJB where you can specify the name of the bean (which by default is the bean implementation's simple class name). So you should change that above code to: @Stateless @EJB(name = "java:global/coo/TestBean1", beanInterface = TestBean.class, *beanName="TestBean1"*) public class TestBean1 implements TestBean{ } @Stateless @EJB(name = "java:global/coo/TestBean2", beanInterface = TestBean.class, *beanName="TestBean2"*) public class TestBean2 implements TestBean{ -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/827308#827308] Start a new discussion in EJB3 at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
