問題2

Choose the statement that best describes the use of Enterprise Beans as JAX-RS root resources:

A. An Enterprise Bean can be made a JAX-RS root resource only if EJB-specific features such as transaction management or security validation are not used.

B. 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 JAXRS root resource, but not both concurrently within the same application.

C. JAX-RS imposes no limitations on the characteristics ofthose Enterprise Beans that can be exposed as JAX-RSresource classes.

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.

正確答案: C

問題3

Given the two classes:

Choose the option that best evaluates the example:

A. This is an invalid example, because EJBs that are to be used as JAX-RS subresources have to match the type of EJB of their "parent" resource.

B. This is an invalid example, because the JAX-specification only allows root resource types to also be EJBs.

C. This is a valid example of two EJBs used as JAX-RS resources, one a root resource and the other a subresource.

D. This is an invalid example, because singleton EJBs used as JAX-RS resources must explicitly state what locking strategy they will require.

正確答案: C
