This is a feature of JBuilder SE and Enterprise.
JBuilder provides several features and tools to support development of applications using the Extensible Markup Language (XML). XML, a platform-independent method of structuring information, separates the content of a document from its structure. XML can be used to exchange data between databases and Java programs. XML support features vary by JBuilder edition.
