Overview

In this example you will learn how to bootstrap a dynamic JAXBContext from an XML Schema.

Bootstrap the JAXBContext

The DynamicJAXBContextFactory is used to create a dyanic JAXBContext. There are several parameters to the create method, but in this example we will focus on the InputStream representing the XML schema.

import java.io.FileInputStream;
import javax.xml.bind.JAXBContext;
import org.eclipse.persistence.jaxb.dynamic.DynamicJAXBContextFactory;
 
public class Demo {
 
    public static void main(String[] args) throws Exception {
        FileInputStream xsdInputStream = new FileInputStream("src/example/dynamic/customer.xsd");
        JAXBContext jaxbContext = DynamicJAXBContextFactory.createContextFromXSD(xsdInputStream, null, null, null);
    }
}

XML Schema

The following XML schema represents the metadata for this JAXBContext.

<xsd:schema 
   xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
   xmlns="www.example.org/customer" 
   targetNamespace="www.example.org/customer"
   elementFormDefault="qualified">
 
   <xsd:complexType name="address">
      <xsd:sequence>
         <xsd:element name="city" type="xsd:string" minOccurs="0"/>
         <xsd:element name="street" type="xsd:string" minOccurs="0"/>
      </xsd:sequence>
   </xsd:complexType>
 
   <xsd:complexType name="customer">
      <xsd:sequence>
         <xsd:element name="name" type="xsd:string" minOccurs="0"/>
         <xsd:element name="address" type="address" minOccurs="0"/>
      </xsd:sequence>
   </xsd:complexType>
 
   <xsd:element name="customer" type="customer"/>
 
</xsd:schema>
