Martha, Ammasa Here's a good name for feshion, there is no Maserati's sense of sight.

What is Martha marshalling? is serialization, translating data structures or object state to a format

Implementation is very simple, Pojo object annotated @xmlrootelement, otherwise it will report an exception

[Com.sun.istack.SAXException2: Cannot compile the type as an element because the type "com.happy.entities.ItemEvaluation" lacks a @XmlRootElement comment)

Crossing Network Introduction: Https://en.wikipedia.org/wiki/Serialization

in computer science, in the context of data storage,  serialization  is The process of Translating data structures or object state to a format that can B E stored (for example, in A file or Memory buffer, or transmitted across A network connection Li NK) and reconstructed later in the same or another computer environment. ^{[1] when the resulting series of bits is reread according to the Serializatio n format, it can be used to create a semantically identical clone of the original object. For many complex objects, such as those-make extensive use of references, this process is not straightforward. Serialization of Object-oriented objectsdoes not include any of their associated methods with which they w Ere previously inextricably linked.}

This process of serializing a object is also called marshalling an object. ^{[2] The opposite operation, extracting a data structure from a series of bytes, was deserialization (which is Also called unmarshalling).}

Https://en.wikipedia.org/wiki/Java_Architecture_for_XML_Binding

Java Architecture for XML Binding (JAXB) is a software framework This allows Java developers to map Java classes to xmlrepresentations. JAXB provides the main features:

The ability to Marshal Java objects into XML and the inverse,

i.e. to UnmarshalXML back into Java objects.

In other words, JAXB allows storing and retrieving data in memory in any XML format, without the need to implement a speci FIC set of XML loading and saving routines for the program ' s class structure. It is similar to and in the xsd.exe XmlSerializer . NET Framework.

JAXB is particularly useful if the specification is complex and changing. In such a case, regularly changing the XML schemadefinitions to keep them synchronised with the Java definitions can be Ti Me consuming and Error-prone.

JAXB is a part of the Java SE platform and one of the APIs in the Java EE platform, and are part of the Java Web Services D Evelopment Pack (JWSDP). It is also one of the foundations for WSIT.

JAXB 1.0 was developed under the Java Community Process as JSR 31. ^{[1] In 2006 JAXB 2.0 is released under JSR 222 and Maintenance Release 2 released in December 2009. [2]}

JAXB (Java Architecture for XML Binding)

JAXB is the abbreviation for the Java Architecture for XML binding. Provides a quick way to

The Java object is converted to XML.

In Jax-WS (One of Java's WebService specifications), JDK1.6 comes with version jax-ws2.1, with the underlying support being JAXB.

Javajava provides automatic serialization which requires that the object is marked by implementing thejava.io.SerializableInterface. Implementing the interface marks the class as "Okay to serialize", and Java then handles serialization internally. There is no serialization methods defined on theSerializableinterface, but a serializable class can optionally define methods with certain special names and signatures if define D, 'll is called as part of the serialization/deserialization process. The language also allows the developer to override the serialization process more thoroughly by implementing another inter Face, theExternalizableinterface, which includes, special methods that is used to save and restore the object's state. There is three primary reasons why objects is not serializable by default and must implement theSerializableInterface to access Java ' s serialization mechanism.

Firstly, not all objects capture useful semantics in a serialized state.

For example, a object was tied to the state of the current Thread JVM. There is no context in which a deserialized Thread object would maintain useful semantics.

Secondly, the serialized state of a object forms part of its classes ' compatibility contract.

Maintaining compatibility between versions of Serializable classes requires additional effort and consideration. Therefore, making a class serializable needs to is a deliberate design decision and not a default condition.

Lastly, serialization allows access to non-transient private members of a class that is not otherwise accessible.

Classes containing sensitive information (for example, a password) should isn't be Seriali Zable nor externalizable. The standard encoding method uses a simple translation of the fields into a byte stream. Primitives as well as non-transient, non-static referenced objects is encoded into the stream. Each of the object is referenced by the serialized object via a field, which is not marked as transient  must also be serialized; And if any object in the complete graph of Non-transient object references are not serializable, then serialization'll FA Il. The developer can influence this behavior by marking objects as transient, or by redefining the serialization for an O Bject So, some portion of the reference graph is truncated and not serialized.

It is possible to serialize Java objects through JDBC and store them into a database. ^{[citation needed] while Swing components do implement the Serializable interface, they is not portable betwe En different versions of the Java Virtual machine. As such, a Swing component, or any component which inherits it, could be serialized to an array of bytes, but it's not guar Anteed} that this storage'll be readable on another machine.
