Web Services and PS Tags Quiz

WSDL 1.1 was submitted to W3C by Ariba, IBM, and Microsoft in 2001 but was never officially adopted as a W3C standard. WSDL 2.0 became a W3C Recommendation in 2007. Therefore, WSDL (especially the original version) is 'not a W3C standard'.

WSDL stands for Web Services Description Language. It is an XML-based language for describing web services, including their location, operations, and message formats. Option C has the correct expansion.

WSDL is pronounced as 'wiz-dull'. The acronym follows standard English pronunciation rules - the 'W' sounds like 'wizard', the 'S' and 'D' are pronounced individually, and the 'L' sounds like 'dull' rather than 'dell'.

UDDI stands for Universal Description, Discovery, and Integration. It is a platform-independent XML-based registry for businesses to list themselves on the internet and discover web services.

UDDI is a directory service for storing information about web services. Like a phone directory, it allows businesses to publish and discover web services. It's not a single file or an entire system - it's a structured directory of service descriptions.

WSDL 1.2 was the first version renamed to WSDL 2.0 during the W3C standardization process. The first working draft of WSDL 1.2 was released by W3C in July 2002. WSDL 2.0 became a W3C Recommendation in 2007.

WSDL was originally developed jointly by Microsoft, IBM, and Ariba. They submitted WSDL 1.1 to the W3C in 2001. Among the options given, Microsoft and IBM is the correct pairing.

In WSDL (Web Services Description Language), the <binding> element has exactly two attributes: name and type. The name attribute provides a unique identifier for the binding, while the type attribute references the port type being bound, making "2" the correct answer.

To answer this question, the user needs to know about the SOAP protocol and its binding element.

The SOAP protocol is an XML-based messaging protocol used to exchange information between different systems. The soap:binding element is used to define the binding of a web service operation to a particular communication protocol.

The soap:binding element has two attributes:

A. style attribute: This attribute is used to define the encoding style used for the message. It specifies whether the message is encoded using the SOAP encoding rules or some other encoding rules.

B. transport attribute: This attribute is used to specify the communication protocol used for the message. It specifies the transport protocol used for sending and receiving the SOAP message. The transport protocol can be HTTP, SMTP, or any other protocol.

C. message attribute: This attribute is not a valid attribute for the soap:binding element. The message attribute is used in the soap:operation element to specify the input and output messages for the operation.

Therefore, the correct answer is:

B. Both 1 and 3

UDDI (Universal Description, Discovery, and Integration) is an XML-based registry for businesses to list themselves on the Internet. Microsoft integrated UDDI services directly into its .NET platform and Windows Server to facilitate Web services discovery, making ".NET platform" the correct choice.

UDDI relies on multiple internet standards. XML provides the data format, HTTP is the transport protocol, and DNS handles domain resolution. These standards come from both W3C (XML, HTTP specifications) and IETF (HTTP, DNS protocols). Therefore, the correct answer includes both organizations.

UDDI is designed as a universal registry that businesses of all sizes and industries can use to publish and discover web services. While WSDL, SOAP, and RDF are technologies, UDDI is specifically the registry/directory service that enables universal discovery and integration across any business sector.

The UDDI (Universal Description, Discovery, and Integration) registry had approximately 220 companies as members at its peak. UDDI was an industry initiative for web service discovery that allowed businesses to publish and discover web services.

The statement correctly describes abstract data definition in the web services context - data is structured as a complete message document or as arguments that map to method invocations. This is fundamental to how SOAP and XML-based web services operate.

PS stands for Presentation Services, which handles the presentation layer in SAP systems. It's not Presentation Section, Primary Screens, or Pages for Server - these are incorrect expansions.

PS tags are designed to enhance security, facilitate easy changes, and promote reusability in development. Since all three listed options are valid benefits and standard usages of PS tags, "none of the above" is the correct choice.

JSP pages created using PS tags cannot be decrypted easily because PS tags are server-side constructs that are processed before the page is served. The resulting output is standard HTML/JSP without the original PS tags, making reverse engineering difficult. False is the correct answer.

The ps:getValue tag retrieves data from the UI Model Object (MO) and renders it on the screen. This is the standard PS tag for displaying values from the UI layer, unlike other tags which serve different purposes like navigation or output operations.

The ps:includeIf tag is the PS equivalent of an if statement, conditionally including content based on a boolean expression. Unlike standard ps:include which always includes content, includeIf adds conditional logic before processing.
