Generate XSD from JAXB Java Classes using Eclipse

Learn to create XML schema document (xsd) from JAXB annotated Java classes using Eclipse IDE.

1) Add JAXB Annotations to Java Classes

First step is to add annotations such as @XmlRootElement, @XmlAccessorType and @XmlElement etc. to your Java classes.

import java.io.Serializable;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "employee")
@XmlAccessorType(XmlAccessType.PROPERTY)
public class Employee implements Serializable {

	private static final long serialVersionUID = 1L;
	
	private Integer id;
	private String firstName;
	private String lastName;
	private Department department;
	
	public Employee() {
		super();
	}

	//Setters and Getters
}

import java.io.Serializable;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "department")
@XmlAccessorType(XmlAccessType.PROPERTY)
public class Department implements Serializable {
	
	private static final long serialVersionUID = 1L;
	
	Integer id;
	String name;
	
	public Department() {
		super();
	}

	//Setters and Getters
}

2) Generate XSD from JAXB Classes

2.1) Navigate to Eclipse Option

File  -> New -> JAXB -> Schema from JAXB Classes

2.2) Select location for generated schema file

2.3) Select JAXB Classes

2.4) Generate xsd files

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="department" type="department"/>

  <xs:element name="employee" type="employee"/>

  <xs:complexType name="employee">
    <xs:sequence>
      <xs:element ref="department" minOccurs="0"/>
      <xs:element name="firstName" type="xs:string" minOccurs="0"/>
      <xs:element name="id" type="xs:int" minOccurs="0"/>
      <xs:element name="lastName" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>

  <xs:complexType name="department">
    <xs:sequence>
      <xs:element name="id" type="xs:int" minOccurs="0"/>
      <xs:element name="name" type="xs:string" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>
</xs:schema>

XSd file has been generated and now you can use it for various application usecases.

Happy Learning !!
