java - Avoid creation of object wrapper type/value in MOXy (JAXB+JSON) -

i'm using moxy 2.6 (jaxb+json).

i want objectelement , stringelement marshalled same way, moxy creates wrapper object when fields typed object.

objectelement.java

public class objectelement {     public object testvar = "testvalue"; } 

stringelement.java

public class stringelement {     public string testvar = "testvalue"; } 

demo.java

import javax.xml.bind.jaxbcontext; import javax.xml.bind.marshaller;  import org.eclipse.persistence.jaxb.jaxbcontextfactory; import org.eclipse.persistence.jaxb.marshallerproperties; import org.eclipse.persistence.oxm.mediatype;  public class demo {      public static void main(string[] args) throws exception {         jaxbcontext jc = jaxbcontextfactory.createcontext(new class[] { objectelement.class, stringelement.class }, null);         marshaller marshaller = jc.createmarshaller();         marshaller.setproperty(marshallerproperties.media_type, mediatype.application_json);          system.out.println("objectelement:");         objectelement objectelement = new objectelement();         marshaller.marshal(objectelement, system.out);         system.out.println();          system.out.println("stringelement:");         stringelement stringelement = new stringelement();         marshaller.marshal(stringelement, system.out);         system.out.println();     }  } 

when launching demo.java, here's output ...

objectelement: {"testvar":{"type":"string","value":"testvalue"}} stringelement: {"testvar":"testvalue"} 

how configure moxy/jaxb make objectelement render stringelement object ? how avoid creation of object wrapper "type" , "value" properties ?

you can use annotation javax.xml.bind.annotation.xmlattribute. render objectelement , stringelement same output.

see following example:

import javax.xml.bind.annotation.xmlattribute;  public class objectelement {     @xmlattribute     public object testvar = "testvalue"; } 

i've used following test class verify correct behaviour.

edit after question updated:

yes it's possible. instead of using xmlattribute before, switched javax.xml.bind.annotation.xmlelement in combination type attribute.

the class declared as:

public class objectelement {   @xmlelement(type = string.class)   public object testvar = "testvalue"; }
