Wsdl Interview Questions with Answers
Question: 1. Explain What Is Wsdl?

Question: 2. What Is Soap, Uddi And Wsdl?
Answer:
SOAP (Simple Object Access Protocol) is a easy protocol for alternate of records.

Companies can publish WSDLs for services they provide and others can get right of entry to those offerings the usage of the statistics in the WSDL.

Question 5. Mention The Operation Types Response Used In Wsdl?
Answer:
WSDL defines four types response. Request response is the most not unusual operation kind.
One manner: It can get hold of a message however will no longer return reaction.
Request response: It gets a request and could go back a reaction.
Solicit response: It sends a request and could watch for response.
Notification: It sends a message but will not await a response.

Question 6. Is It Possible To Generate The Source Code For An Asp.Net Web Service From A Wsdl?
Answer:
The Wsdl.Exe tool (.NET Framework SDK) may be used to generate source code for an ASP.NET web provider with its WSDL hyperlink.
Question: 7. Explain What Does The “types” Define In Wsdl?
Answer:
The kind detail defines all of the facts types used between the server and the patron.
To outline statistics kinds WSDL uses the W3C XML Schema Specification as its default choice.
Type element is not required if the carrier makes use of handiest easy XML schema types like integers and strings.
To reuse the kind with multiple net offerings, WSDL allows to define types in a separate elements.

Question eight. What Is Web Service?
Answer:
We can count on an internet service as a technique over the net, It truly takes the parameter and supply the result in the XML format for independablity.Furthermore, It use SOAP formatted XML envelops and use WSDL for interfacing.
Question: 9. Explain What Is “soap: Body”?
Answer:
“soap: body” is a SOAP extension detail used as a sub detail of the “wsdl: input/output” in the wsdl binding and operation. It is used to offer facts on how the content material of the SOAP frame element is constructed.

Question 10. What Is The Meaning Of Semantic Connotations?
Answer:
A semantic annotation is additional statistics in a record that defines the semantics of part of that report. In this technical observe, the semantic annotations are additional statistics factors in a WSDL file. They outline semantics by regarding a part of a semantic version that describes the semantics of the a part of the report being annotated.
The WSDL record paperwork the anchor factor for Web offerings description. Building at the descriptive functionality of WSDL, a mechanism is provided to annotate the skills and requirements of Web services with semantic standards referenced from a semantic version. To do that, mechanisms are furnished annotate the service and its inputs, outputs and operations. Additionally, we provide mechanisms to specify and annotate preconditions and effects of Web Services. These preconditions and outcomes together with the semantic annotations of inputs and outputs can enable automation of the technique of carrier discovery.

Question eleven. Explain How Wsdl Can Bind To Soap?
Answer:
The binding is feasible with the aid of attributes- call and type attributes. The call attribute defines the name of the binding and kind attribute defines the port for the binding.
While, for SOAP binding you need to claim attributes- delivery and fashion. The shipping attributes defines the SOAP protocol (HTTP) whilst fashion attribute defines the “rpc” or “report”.

Question 12. How Do I Get Started With A Web Services?
Answer:
The simplest way to get started out with Web offerings is to examine XML-RPC. Check out the XML-RPC specification or study my ebook, Web Services Essentials. O’Reilly has also lately released a ebook on Programming Web Services with XML-RPC with the aid of Simon St.Laurent, Joe Johnston, and Edd Dumbbells.
Once you have got found out the fundamentals of XML-RPC, move onto SOAP, WSDL, and UDDI. These subjects are also covered in Web Services Essentials. For a comprehensive treatment of SOAP, test out O’Reilly’s Programming Web Services with SOAP, with the aid of Doug Tidwell, James Snell, and Pavel Kulchenko.

Question 14. List Out The Characteristics Of Port And Service In Wsdl?
Answer:
A carrier can also have multiple endpoint with every one defined via its own port detail.
The port detail pertains to a selected binding, and consists of information on the way to get entry to it (URI).
Different ports characterize one-of-a-kind binding for the identical port type- enabling the identical functionality to be handy thru multiple transport protocols and interaction styles.
Question 15. Mention What Things Need To Be Taken Care For Ports While Binding?
Answer:
While binding,
A port must not determine more than one deal with.
A port must not determine any binding facts aside from deal with records.

Question sixteen. Explain What Is The Difference Between Binding And Port Type In Wsdl?
Answer:
WSDL Port: The WSDL port kind detail defines a set of operations referred to as an interface in maximum environments. Each operation includes a aggregate of input and output elements. The order of these elements determine the message change sample (MEP).
WSDL Binding: The WSDL binding element describes the details of the usage of precise port Type with a given protocol.

Question 17. Explain What Is The Difference Between Soap Message And Wsdl?
Answer:

Question 20. Explain How Endpoints Are Defined In Wsdl?
Answer:
Endpoints represent an instantiated provider; they may be determined by combining a binding and the networking info used to reveal the endpoint.
