java - How do I serialize a JAXBElement? -

i using:

• gson 2.3.1
• apache-cxf-3.1.1
• jboss eap 6.4

i using wsdl2java create webservice client wsdl.

i generate classes with:

@xmlelementref(name = "fmla_code", namespace = "http://www.ultipro.com/contracts", type = jaxbelement.class) protected jaxbelement<string> fmlacode; 

when getting object webservice call want make json response caller

employmentinformationgetresponse response =             port.getemploymentinformationbyemployeeidentifier(employeenumberidentifier); gsonbuilder gsonbuilder = new gsonbuilder(); gsonbuilder.registertypehierarchyadapter(employmentinformationgetresponse.class, new employmentinformationgetresponseadapter()); gson gson = gsonbuilder.disablehtmlescaping().create(); string s = gson.tojson(response); system.out.println(s); 

the result contains

fmlacode=javax.xml.bind.jaxbelement@3191394e 

what best way me value?

i can prefer not alter generated classes, might need generated again later.

i tried create type adapter jaxbelement, not called:

public class jaxbelementadapter extends typeadapter<jaxbelement> {      @override     public void write(jsonwriter jsonwriter, jaxbelement jaxbelement) throws ioexception {         if (jaxbelement == null) {             jsonwriter.nullvalue();             return;         }         jaxbelement e = jaxbelement;         jsonwriter.value(e.getvalue() != null ? e.getvalue().tostring() : "");     }      @override     public jaxbelement read(jsonreader jsonreader) throws ioexception {         return null;     } } 

i used code register adapter:

    gsonbuilder.registertypehierarchyadapter(jaxbelement.class, new jaxbelementadapter()); 

here generated employmentinformationgetresponse

import javax.xml.bind.jaxbelement; import javax.xml.bind.annotation.xmlaccesstype; import javax.xml.bind.annotation.xmlaccessortype; import javax.xml.bind.annotation.xmlelementref; import javax.xml.bind.annotation.xmltype; import java.util.list;  /**  * <p>java class employmentinformationgetresponse complex type.  *   * <p>the following schema fragment specifies expected content contained within class.  *   * <pre>  * &lt;complextype name="employmentinformationgetresponse"&gt;  *   &lt;complexcontent&gt;  *     &lt;extension base="{http://www.ultipro.com/contracts}getresponse"&gt;  *       &lt;sequence&gt;  *         &lt;element name="results" type="{http://www.ultipro.com/contracts}arrayofemploymentinformation" minoccurs="0"/&gt;  *       &lt;/sequence&gt;  *     &lt;/extension&gt;  *   &lt;/complexcontent&gt;  * &lt;/complextype&gt;  * </pre>  *   *   */ @xmlaccessortype(xmlaccesstype.field) @xmltype(name = "employmentinformationgetresponse", proporder = {     "results" }) public class employmentinformationgetresponse     extends getresponse {      @xmlelementref(name = "results", namespace = "http://www.ultipro.com/contracts", type = jaxbelement.class)     protected jaxbelement<arrayofemploymentinformation> results;      /**      * gets value of results property.      *       * @return      *     possible object      *     {@link jaxbelement }{@code <}{@link arrayofemploymentinformation }{@code >}      *           */     public jaxbelement<arrayofemploymentinformation> getresults() {         return results;     }      /**      * sets value of results property.      *       * @param value      *     allowed object      *     {@link jaxbelement }{@code <}{@link arrayofemploymentinformation }{@code >}      *           */     public void setresults(jaxbelement<arrayofemploymentinformation> value) {         this.results = value;     }

i'm not sure why code isn't working. think problem jaxbelement parameterized type, need specify generic type parameter.

try instead when registering typeadapter:

gsonbuilder.registertypeadapter(        new typetoken<jaxbelement<string>>(){}.gettype(),        new jaxbelementadapter());
