A practical guide to JAXB 2.0
Take a peek at its new features
The directory structure of the JAXB2 project is shown in Figure 2.
Compiling an XML Schema
In this section, we will bind the catalog schema, catalog.xsd, to Java classes with the xjc
compiler. We shall configure xjc
as an external tool in Eclipse. Select Run>External Tools>External Tools. In the External Tools frame, right-click on the Program node and select New to create a new configuration as shown in Figure 3.
Also, set environment variables JAVA_HOME
and JAXB_HOME
in the external tool configuration for xjc
in the Environment tab, as shown in Figure 4.
Run xjc
compiler on the example schema, catalog.xsd. Select catalog.xsd file in the Package Explorer window and then Run>External Tools>XJC.
The output from the XJC compiler is shown in Figure 5.
Schema-derived classes get generated in the gen_source
folder, as shown in Figure 6.
Java classes and interfaces are generated in package generated
, by default. For each xsd:complexType
schema component, one value class gets generated, instead of an interface and an implementation class. For example, for catalogType
complexType
a Java value class CatalogType.java
gets generated. An ObjectFactory.java
class also gets generated. The factory class consists of create methods to create Java value class objects.
