What are the functions of the stub object in RMI?

What are the functions of the stub object in RMI?

RMI uses a standard mechanism (employed in RPC systems) for communicating with remote objects: stubs and skeletons. A stub for a remote object acts as a client’s local representative or proxy for the remote object.

What is the use functionality of a stub skeleton?

The stub hides the serialization of parameters and the. network-level communication in order to present a simple invocation mechanism to the caller. The skeleton is responsible for dispatching the call to the actual remote object implementation.

What is the purpose of stub and skeleton classes?

The stub performs type checking. The skeleton is defined in a class which implements the interface stub. When a caller wants to perform remote call on the called object, it delegates requests to its stub which initiates communication with the remote skeleton.

What is the difference between stub and skeleton in Web service explain briefly with a diagram?

Stub and Skeleton Skeleton belongs to service provider side and stub belongs to receiver side. At lower level stub and skeleton communicate with each other. From client side the business objects communicates with stub objects and stub takes the responsibility form the message and invoke the web service.

What is marshalling and Unmarshalling in RMI?

During communication between two machines through RPC or RMI, parameters are packed into a message and then sent over the network. This packing of parameters into a message is called marshalling. On the other side these packed parameters are unpacked from the message which is called unmarshalling.

What is Marshaller and Unmarshaller?

As stated in the introduction, a marshaller serializes an object to XML, and an unmarshaller deserializes XML stream to an object. In this section, we will describe the two Spring interfaces used for this purpose.

What is the difference between marshalling and serialization?

Marshaling and serialization are loosely synonymous in the context of remote procedure call, but semantically different as a matter of intent. In particular, marshaling is about getting parameters from here to there, while serialization is about copying structured data to or from a primitive form such as a byte stream.

What is Marshall and Unmarshall?

Marshalling is converting the data present in an object into a an xml format and viewing it in an xml format and unmarshalling is reverse of it converting an xml file into an object.

What is Jaxp and JAXB?

JAXP is Java API for XML Processing, which provides a platform for us to Parse the XML Files with the DOM Or SAX Parsers. Where as JAXB is Java Architecture for XML Binding, it will make it easier to access XML documents from applications written in the Java programming language.

What is Marshall?

transitive verb. 1 : to place in proper rank or position marshaling the troops. 2 : to bring together and order in an appropriate or effective way marshal arguments marshaled her thoughts before answering the question.

What is Unmarshall?

“Unmarshalling” is the process of converting some kind of a lower-level representation, often a “wire format”, into a higher-level (object) structure. Other popular names for it are “Deserialization” or “Unpickling”.
