Protocol stack of XML Web Services
Explain the protocol stack of XML Web Services.
Expert
Web service protocol stack is the protocol stack (that is, a stack of computer networking protocols) which is employed to define, locate, implement, and form Web services interact with one other. The Web service protocol stack usually stacks four protocols:
(Service) Transport Protocol: accountable for transporting messages among network applications and comprises protocols like HTTP, SMTP, FTP, and also the more recent Blocks Extensible Exchange Protocol (BEEP).
(XML) Messaging Protocol: accountable for encoding messages in a general XML format and hence they can be understood at either end of the network connection. Presently, this area comprises such protocols as XML-RPC, WS-Addressing, and SOAP.
(Service) Description Protocol: employed for explaining the public interface to a particular Web service. The WSDL interface format is usually utilized for this purpose.
(Service) Discovery Protocol: centralizes services into a general registry such that network Web services can publish their position and description, and makes it simple to discover what services are accessible on the network. Universal Description Discovery and Integration (abbreviated as UDDI) was intended for this aim, however it has not been broadly adopted.
Unchecked exception: An exception for which it is not needed to give a local try statement or to propagate through a throws clause stated in the method header. An exception which is not handled will cause program annihilation when it is thrown.
Operator: It is a symbol, like -, = or ?: taking one, two or three operands and yielding an outcome. The operators are employed in both arithmetic and Boolean expressions.
Define the term Top level class: It is a class defined either at outermost level of a package or the static nested class.
Define Identifiers and their naming convention in brief?
Describes the cases where you need to double clock a signal before presenting this to a synchronous state machine?
What do you mean by the term assembly condition codes?
State Null character: The \u0000 character. The care must be taken not to confuse this with null reference.
Block: The statements and declarations are enclosed between a matching pair of curly brackets ({ and }). For example, a class body is a block, as it is a method body. The block surrounds a nested scope level.
Copy constructor: It is a constructor which takes a single argument of similar class. For illustration: public class Point {
What is an Instantiation: It is a creation of an instance of a class, i.e., an object.
