JAXB binding to override or remove XMLSchemaType xs:token

Question

I am generating model classes from an xsd using the maven jaxb2 plugin. The xsd specifies certain elements with type=xs:token as follows:

<xs:element name="medium_text" type="xs:token"/>

This results in the following annotations being added to the field in the generated model:

@XmlJavaTypeAdapter(CollapsedStringAdapter.class)
@XmlSchemaType(name="token")
protected String medium_text;

The problem is the CollapsedStringAdapter removes new lines etc (which is the correct behaviour for xs:token) but I want to avoid this.

How can remove the xs:token type from the element or change it to xs:string using JAXB bindings? The easy solution is to remove the type from the xsd but is it possible using bindings without modifying the xsd?

Answer 1

You can use the following in your binding file.

<jxb:bindings schemaLocation = "schema.xsd">
   <jxb:bindings node = "//xs:element[@name='medium_text']">
             <jxb:javaType name="java.lang.String"/> 
   </jxb:bindings>
</jxb:bindings>

This results in the following:

@XmlElement(name = "mid_text", required = true)
@XmlJavaTypeAdapter(Adapter1 .class)
@XmlSchemaType(name = "token")
protected String midText;

Adapter1 however is harmless and does not change the string value.

Also if you want to do this to all your tokens you can add a globalBinding

  <jxb:globalBindings>
            <jxb:javaType name="java.lang.String"
                xmlType="xs:token" />
  </jxb:globalBindings>
