A developer is given a WSDL for an existing Web service. What is the correct sequence of steps that must be taken to use that Web service?

B. use a utility (such as wsimport) to read the WSDL and generate a service endpoint interface

C. register the WSDL with wsgen, bind to the stubs, and then call methods on the interface

D. receive the service using RMI, parse the XML using JAXP, create Java objects using JAXR, and then return those Java objects

Which statement is true about .Net and WCF interoperability for this data?

A. Based on the fragment, enumerations map well between Java and .Net.

B. The subtle differences in the variable names make it clear these enumerations are NOT interoperable.

Which two code fragments are valid for adding an attachment in SAAJ? (Choose two.)

A. SOAPMessage object. AttachmentPart attachment=request.createAttachementPart(); String stringContent = Update total; attachment.setContent(stringContent,text/plain); attachment.setContentID(update_total); request.addAttachmentPart(attachment);

B. SOAPMessage object. Attachment attachment=request.createAttachement(); String stringContent = Update total; attachment.setContent(stringContent,text/plain); attachment.setContentID(update_total); request.addAttachment(attachment);

C. URL url = new URL(http://eshop.com/products/tb.jpg); DataHandler datahandler = new DataHandler(url); AttachmentPart attachment = request.createAttachmentPart(dataHandler); attachment.setContentID (attached_image); request.addAttachmentPart(attachment);

A Java EE 5 application contains business logic composed of EJB3 beans. All current clients are Java applications accessing the business logic using RMI. Some clients are remote (running in different JVMs) and some are local (running in the same JVM). Which two occur if EJB components are exposed as Web services? (Choose two.)

A. New applications can use published interfaces to access existing applications.

B. Current local clients must access the Web services in the application as an URL.

C. WSDL documents define common types for all clients.

D. Current remote clients must switch from RMI to Web service access.

E. Delivery of messages is guaranteed for local clients.

A company has contracted a developer to create their new accounting system. The system the developer will replace runs a monolithic web application using one web server and one database server. Technical requirements state the developer must write the business logic in Java, deploy to the application server and push the presentation logic onto the web servers. What are three characteristics of services in the proposed Service Oriented Architecture? (Choose three.)

A. Services are coarse grained.

B. Services are finely grained.

C. Services are loosely coupled.

D. Services are tightly coupled.

E. Clients must be implemented in the Java technology.

F. Services are platform agnostic, network-addressable web APIs.
