Choose two options from the following that can be achieved by setting the standard BindingProvider properties on a SEI proxy: (Choose two)

• A.Specifying web service endpoint address for service invocations
• B.Validating against schema for outgoing client messages
• C.Configuring HTTP Basic Authentication credentials to access a service
• D.Adding additional SOAP headers for outgoing messages

A student developer has created a new library of math functions to share with friends in a linear algebra class. The developer is having difficulty getting people to come over to the dorm to see the new code library, so he decides to deploy it as a Web service so that everyone can enjoy the features via the Internet. One of the functions has this WSDL definition:
<portType name="MyMathLib"><operation name="incCtr"><input message="tns:incCtr"/></operation></portType>
Which two statements are true about this Web service? (Choose two.)

• A.It must NOT send a SOAP fault back to the sender.
• B.This is an asynchronous receive.
• C.The client must use SOAPFaultException to display any errors.
• D.It must send a SOAP fault back to the sender.
• E.This indicates a one-way message exchange pattern

Which two statements are true about the interoperability of Web services developed using the Java EE 6 platform? (Choose two.)

• A.The service must be published in both the .NET and Java UDDIs.
• B.Interoperability is improved by restricting access only to Java clients.
• C.Testing for WS-I Profile conformance improves interoperability.
• D.The signature of Web service methods is limited to parameters and return types that are concrete types and simple arrays of concrete types.
• E.EJB-based endpoints are more difficult for .NET clients to access.
• F.Only servlet-based endpoints are used when exposing services to non-Java clients.

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 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.
• B.The attempt will fail, because there is more to the difference between XML-based and JSON-based interactions than just the data representation used.
• C.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.
• D.The attempt will fail, because JAX-RS does not support both XML- and JSON- based restful services in parallel.

Which of the following is NOT a correct way of configuring handlers on a Web Service client ? (Choose one)

• A.Specify the handlers in jaxws-catalog.xml and make it available in the classpath of the client
• B.Programmatically configure the handlers by setting a custom HandlerResolver on the service instance and create proxies from that service.
• C.Create a handlerchain as list of handlers and call setHandlerChain() with that list on the Binding object.
• D.Specify handlers in handler chain configuration XML file and add @HandlerChain referencing handler configuration file to the Web Service references for clients running in JavaEE Container.
