The Open Source Zone

JaxMe 2 is an open source implementation of JAXB, the specification for Java/XML binding.

A Java/XML binding compiler takes as input a schema description (in most cases an XML schema but it may be a DTD, a RelaxNG schema, a Java class inspected via reflection or a database schema). The output is a set of Java classes:

• A Java bean class compatible with the schema description. (If the schema was obtained via Java reflection, then the original Java bean class.)
• An unmarshaller that converts a conforming XML document into the equivalent Java bean.
• Vice versa, a marshaller that converts the Java bean back into the original XML document.

In the case of JaxMe, the generated classes may also

• Store the Java bean into a database. Preferrably an XML database like eXist, Xindice, or Tamino, but it may also be a relational database like MySQL. (If the schema is sufficiently simple. :-)
• Query the database for bean instances.
• Implement an EJB entity or session bean with the same abilities.
