I have an XML

<SubTask id="3">
            <state>enabled</state>
       </SubTask

There is a JAXB class with two variable "id" and "state".Now when I unmarshall the above XML, I don't want to load the "id" element into the Java object. How can I do this programmatically? I don't want to change the Java class.

Reset to default

Assuming your JAXB class has

   @XmlElement(name="state")
   String state;

then you should use @XmlTransient to skip deserializing of element.

   @XmlTransient(name="state")
   String state;

Other possible solution is, remove those field from the class.

  • The JAXB class resides in a third party jar. Creating a new JAXB class will lead to more changes in the existing code.
