Generate Java Classes from xsd File

These are the steps to create java classes from xsd files from Eclipse using the JAXB2 Maven plugin:

 

1) Create a Maven project in Eclipse

 

2) Add the JAXB2 Maven plugin to the pom.xml file

In the pom.xml file:

• Add the JAXB2 plugin dependency.
• Configure the location of schema files.
• Configure the location of the global binding directory.
• Configure the directory for generated classes.

<plugin>
	<groupId>org.jvnet.jaxb2.maven2</groupId>
	<artifactId>maven-jaxb2-plugin</artifactId>
	<version>0.9.0</version>
	<executions>
		<execution>
			<goals>
				<goal>generate</goal>
			</goals>
		</execution>
	</executions>

	<configuration>
		<schemaDirectory>${project.basedir}/src/main/xsd</schemaDirectory>
		<schemaIncludes>
			<include>Patient.xsd</include>
		</schemaIncludes>
		<bindingDirectory>${project.basedir}/src/main/xsd</bindingDirectory>
		<bindingIncludes>
			<include>global.xjb</include>
		</bindingIncludes>
		<generateDirectory>${project.basedir}/src/generated</generateDirectory>
	</configuration>
</plugin>

 

3) Configure datatype binding rules in the xjb file

This is the content of the global.xjb file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxb:bindings version="2.0"
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
  xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  jaxb:extensionBindingPrefixes="xjc">
   
 <jaxb:globalBindings>
    <xjc:simple />
    <xjc:serializable uid="-1" />
    <jaxb:javaType name="java.util.Calendar" xmlType="xs:dateTime"
      parseMethod="javax.xml.bind.DatatypeConverter.parseDateTime"
      printMethod="javax.xml.bind.DatatypeConverter.printDateTime" />
  </jaxb:globalBindings>
</jaxb:bindings>

 

 

4) Create Java Classes

Right-click on the project and select Run As > Maven Generate Sources.  The classes should be created in the generate directory mentioned in step 2.  The package name will match the target namespace in the xsd file.
