Question

There is little problem with JAXB.

Given:

• Java 1.5; jaxb -jars from jaxws-2_0.
• .xsd scheme and genera

Answer 1

default value that is in annotations works only after unmarshalling.
unmarshal this

and you will get object with default values (-1, -1.0, "Default")

If you want set default values to marshalling, you should do this

public class Document {
    @XmlElement(name = "d_int", defaultValue = "-1")
    protected int dInt = 100;
    @XmlElement(name = "d_double", defaultValue = "-1.0")
    protected double dDouble = -100;
    @XmlElement(name = "d_string", required = true, defaultValue = "Default")
    protected String dString = "def";
...
}    

jaxb generate default values only for unmarshalling
