JAXB List Tag creating inner class

Question

So we have an XSD type in the form:

Answer 1

You could do the following:

package example;

import java.util.List;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="Foo")
public class Foo {

    private List bar;

    public List getBar() {
        return bar;
    }

    @XmlElementWrapper(name="Bars")
    @XmlElement(name="Bar")
    public void setBar(List bar) {
        this.bar = bar;
    }

}

and

package example;

public class Bar {

}

Then you can process your XML using the following code;

package example;

import java.io.File;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Foo.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        Foo foo = (Foo) unmarshaller.unmarshal(new File("src/forum128/input.xml"));

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(foo, System.out);
    }
}
