• Question 72:

  Choose the option that best describe the deployer's choices, when deploying an EJB that is also exposed as a RESTful web service using JAX-RS (Choose one):

  C. The EJB can be deployed to any EJB or web container that would support local references to the EJB from the JAX-RS runtime in the web container.
  D. The EJB can be deployed to an EJB or web container that is visible to the JAX-RS runtime, even on an application server separate from the JAX-RS runtime, since EJBs support local or remote interactions via RMI.
  C. The EJB can be deployed to any EJB or web container that would support local references to the EJB from the JAX-RS runtime in the web container.

  B. JAX-RS imposes no limitations on the characteristics ofthose Enterprise Beans that can be exposed as JAX-RSresource classes.
  C. An Enterprise Bean that is exposed as a JAX-RS root resourcecan no longer be used directly as a remote bean itself - thebean implementation class can be accessed via the remote EJBdistributed framework (RMI), or a JAX- RS root resource, but not both concurrently within the same application.
  D. An Enterprise Bean that is exposed as a JAX-RS root resource supports all the same features as a JAX-RS resource that it supports as an EJB.
