java - JAXB Marshaller does not print attributes of subclass -


i have got class "contract" contains list of instances of concrete subclasses of abstract class "condition".

@onetomany(mappedby = "givenoncontract", cascade =  cascadetype.all, fetch = fetchtype.lazy, targetentity = condition.class) @privateowned @xmlelement(name = "condition", type =  modell.contract.condition.condition.class) @xmlelementwrapper(name = "conditions") private list<condition> conditions = new arraylist<condition>();

the class "condition" has got attribute "sortingnumber". add list in contract instance of class "manualcondition" (a concrete subclass of "condition"). class has got attribute named "value"

when marshall object tree (contract->conditions) attribute of "condition" printed, not 1 of subclass manualcondition.

public static string printxml(abstractmodelobject objekt) throws  jaxbexception {     final jaxbcontext context = jaxbcontext.newinstance(objekt.getclass());     final bytearrayoutputstream output = new bytearrayoutputstream();      final marshaller marshaller = context.createmarshaller();     marshaller.setproperty(marshaller.jaxb_fragment, boolean.false);     marshaller.setproperty(marshaller.jaxb_formatted_output, boolean.true);     marshaller.setadapter(new productconfigurationxmladapter(null));     marshaller.marshal(objekt, output);     final string jaxbencoding = (string)  marshaller.getproperty(marshaller.jaxb_encoding);      try {         return new string(output.tobytearray(), jaxbencoding);     } catch (unsupportedencodingexception uee) {         throw new runtimeexception(uee);     } }

when add annotation @xmlseealso(manuellekondition.class) before class definition of "condition", attributes of subclass manualcondition printed. solution not satisfactory us, because have add annotation several places in our code (there far more classes 2 mentioned)

does know easier solution print attributes including ones on subclasses? somehow possible via configuration/setting of properties on marshaller?

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
