What is marshalling and unmarshalling of XML in Java?

Marshalling is the process of transforming Java objects into XML documents. Unmarshalling is the process of reading XML documents into Java objects. The JAXBContext class provides the client’s entry point to the JAXB API. It provides API for marshalling, unmarshalling and validating.

What is meant by marshalling unmarshalling?

To “marshal” an object means to record its state and codebase(s) in such a way that when the marshalled object is “unmarshalled,” a copy of the original object is obtained, possibly by automatically loading the class definitions of the object.

How do you Unmarshal an XML string?

What is marshalling and unmarshalling in distributed systems?

Unmarshalling refers to the process of transforming a representation of an object that is used for storage or transmission to a representation of the object that is executable.

What is marshalling and unmarshalling in Java?

The server reads the xml message and converts it into the Java object for further processing at server side which is called Unmarshalling. This mechanism of Marshalling and Unmarshalling is provided by JAXB which stands for Java Architecture for XML Binding. Let’s look at an example.
