  • What is an EJB, and what does it do? - Stack Overflow
    The lifecycle of EJBs is container managed As required, it creates EJB instances, clears and initializes stateful session bean state, passivates activates, and calls lifecycle callback methods, so EJB code can participate in lifecycle operations to acquire and release resources, or perform other initialization and shutdown behavior
  • java - What does the @EJBs annotation do? - Stack Overflow
    I had a web project, jee 6, with ejbs in it and i didnt have to specify name attribute with @EJB, once I moved ejbs to separate ejb jar (still same ear) weblogic 12 1 2 tells me "The ejb-ref does not have an ejb-link and the JNDI name of the target Bean has not been specified" –
  • What is the meaning of @ejb annotation in java? [duplicate]
    Application servers support bindings at deployment time This is usually implemented by performing a lookup If no other binding information is provided and the bean interface (beanInterface or the field type) is only implemented by a single EJB in the application, then the EJB specification requires that it fall back to that
  • What is the difference between @Inject and @EJB
    Yes, the CDI container knows whether a type is an EJB interface, so it will still coordinate with the EJB container to obtain an EJB proxy, which allows the EJB container to control the actual bean lifecycle, and then the CDI container will wrap the EJB proxy with a CDI proxy as needed (e g , contextual proxy is meaningless for a stateless bean but meaningful for a stateful bean)
  • Web Services vs EJB vs RMI, advantages and disadvantages?
    Between EJB and RMI, EJB would certainly be better - it has everything RMI has and much more via the container (object pooling, transaction management, etc ) Between EJB and web services, web services would give you more portability if you want to be able to call them from non-java apps in the future
  • java - Should I use @EJB or @Inject - Stack Overflow
    The @EJB is used to inject EJB's only and is available for quite some time now @Inject can inject any managed bean and is a part of the new CDI specification (since Java EE 6) In simple cases you can simply change @EJB to @Inject
  • jpa - Testing an EJB with JUnit - Stack Overflow
    It can take a little while to adjust to the mindset of testing behavior using stubs, but it is a very powerful technique for testing the business logic of your EJB 3 1 beans because it lets you isolate and narrow the scope of each test to exclude external dependencies
  • ejb - How to call session bean from jsp - Stack Overflow
