An airline built and deployed a back-end application to manage reservations. To support interoperability with as large a base of standalone client applications as possible, the services provided by this back-end application are exposed as XML-based restful web services. Management just added a new requirement that AJAX-based web application clients be supported, too. One of the developers suggested that it is enough to extend the existing application to support both XML-based and JSON-based restful web services. Assuming the developer is correct, choose the sentence that best describes an attempt to introduce this ability as this developer suggests (Choose one):

• A.The attempt will fail, because there is more to the difference between XML-based and JSON-based interactions than just the data representation used.
• B.The attempt will be trivial to implement, since JAX-RS just needs for the application to specify that both XML- and JSON-based interaction will be supported.
• C.The attempt can succeed, but it will require a significant amount of new code, since JAX-RS does support both XML- and JSON-based interaction - but not single resource can support both kinds of interaction simultaneously.
• D.The attempt will fail, because JAX-RS does not support both XML- and JSON- based restful services in parallel.

Given that a web service endpoint is based on the stateless session EJB:

Which is true about the security roles of clients of MrBean? (Choose one)

• A.Both EJB and web service clients must NOT be in role A.
• B.Both EJB and web service clients must be in role A.
• C.Only EJB clients must be in role
• D.Only Web Service clients must be in role A.

In the code fragment below, the client will use os to upload data to the web service provider.

Choose the statement that must be placed in line 5, to ensure this fragment works as intended. (Choose one)

• A.connection.setIfModifiedSince(new Date().getTime());
• B.connection.setDoOutput(true);
• C.connection.setAllowUserInteraction(true);
• D.connection.setUseCaches(false);

Where can a developer specify confidentiality or integrity constraints on communications with a Enterprise Bean exposed as a JAX-RS root resource?(Choose one)

• A.In the deployment descriptor for the web application that is hosting the JAX-RS resource.
• B.In the deployment descriptor for the EJB exposed as a root resource.
• C.In the vendor-specific configuration file for the container that is hosting the JAX-RS resource.
• D.As annotations on the EJB exposed as a root resource.

According to the WS-I Basic Profile 1.0a, what is true about the SOAP 1.1 encodingStyle attribute?

• A.It can occur anywhere in a message.
• B.WS-I Basic Profile 1.1 does NOT give any guidance because encodingStyle is a SOAP 1.1 attribute.
• C.It can only be declared on children Header elements.
• D.It cannot be used with elements qualified by the http://schemas.xmlsoap.org/soap/envelope namespace.
• E.It can be declared on any children of the Body elements of rpc-literal messages.
