Jakarta XML Binding
open-in-new
<p>Jakarta XML Binding (JAXB; formerly Java Architecture for XML Binding) is a <a href="/facts/Software_framework/EWasA8sG">software framework</a> that allows <a href="/facts/Jakarta_EE/7AAStd35">Java EE</a> developers to map Java <a href="/facts/Class_(computer_science)/zvzkSAtE">classes</a> to <a href="/facts/XML/clNgUfWk">XML</a> representations. JAXB provides two main features: the ability to <a href="/facts/Marshalling_(computer_science)/NhcdrmhR"><i>marshal</i></a> Java <a href="/facts/Object_(computer_science)/eX99dtAw">objects</a> into XML and the inverse, i.e. to <i>unmarshal</i> XML 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 specific set of XML loading and saving routines for the program's class structure. It is similar to xsd.exe and XmlSerializer in the <a href="/facts/.NET_Framework/J6QDAUhP">.NET Framework</a>. </p><p>JAXB is particularly useful when the specification is complex and changing. In such a case, regularly changing the <a href="/facts/XML_Schema_(W3C)/X6Uly3dm">XML Schema</a> definitions to keep them synchronised with the Java definitions can be time-consuming and error-prone. </p><p>JAXB is one of the <a href="/facts/Application_programming_interface/GMlN4vUr">APIs</a> in the Jakarta EE platform (formerly Java EE), part of the <a href="/facts/Java_Web_Services_Development_Pack/eXopc0BS">Java Web Services Development Pack</a> (JWSDP), and one of the foundations for <a href="/facts/Web_Services_Interoperability_Technology/C13TLrVL">WSIT</a>. It was also part of the <a href="/facts/Java_SE/1HMPhdsv">Java SE</a> platform (in version Java SE 6–10). As of Java SE 11, JAXB was removed. For details, see <a href="http://openjdk.java.net/jeps/320">JEP 320</a>. </p><p>JAXB 1.0 was released in 2003, having been developed under the <a href="/facts/Java_Community_Process/LFQVV4Ik">Java Community Process</a> as JSR 31. In 2006 JAXB 2.0 was released under JSR 222 and Maintenance Release 2 released in December 2009. <a href="/facts/Reference_implementation/k9B97xel">Reference implementations</a> for these specifications were available under the <a href="/facts/CDDL/f1gcKWVz">CDDL open source license</a> at <a href="/facts/Java.net/Cmm1hNn1">java.net</a>. </p>
