java - JAXB "(variable) is not a valid property" on a ResponseWrapper -

i have webservice:

@webservice() public interface wmcservice {      @webmethod(operationname="getgroupinfofromuserid")     @responsewrapper(classname="wmc.web.service.basicgroupwrapper")     @webresult(name="basicgroup")     basicgroup getgroupinfofromuserid(@webparam(name = "id") long id); }  @webservice(endpointinterface="wmc.web.service.wmcservice", servicename="wmcservice") public class wmcserviceimpl implements wmcservice {      @override     public basicgroup getgroupinfofromuserid(long id) {         userhelper uh = new userhelper();         wmcuser user = uh.getbyid(id);         if (user != null) {             return user.getbasicgroup();         } else {             return null;         }     } } 

and have responsewrapper:

@xmlrootelement() @xmltype(name="group") @xmlaccessortype(xmlaccesstype.field) public class basicgroupwrapper {      @xmlelement(name="groupname")     private string groupname;     @xmlelement(name="groupid")     private long groupid;     @xmltransient     private basicgroup basicgroup;      public string getgroupname() {         return groupname;     }      public void setgroupname(string groupname) {         this.groupname = groupname;     }      public long getgroupid() {         return groupid;     }      public void setgroupid(long groupid) {         this.groupid = groupid;     }      public void setbasicgroup(basicgroup group) {         this.groupname = group.getgroupname();         this.groupid = group.getid();         this.basicgroup = group;     }      public basicgroup getbasicgroup() {         return basicgroup;     }  } 

when test operation following error can't google solution to. maybe can help.

caused by: javax.xml.bind.jaxbexception: basicgroup not valid property on class wmc.web.service.basicgroupwrapper             @ com.sun.xml.bind.v2.runtime.jaxbcontextimpl.getelementpropertyaccessor(jaxbcontextimpl.java:971)             @ com.sun.xml.ws.server.sei.endpointresponsemessagebuilder$doclit.<init>(endpointresponsemessagebuilder.java:203)         ... 34 more 

@webresult(name="basicgroup") not part of wsdl since it's marked xmltransient:

@xmltransient private basicgroup basicgroup; 

so won't able pick out part of response.
