how can I map the subsequent XML file to the right inheriting class. The problem is, that I have four different API methods, this is a response of one of the methods named "api_search_location" \[code\]<?xml version="1.0" encoding="UTF-8"?><ft> <response> <client device="" appName="" clientId="123" appVersion=""/> <responseType>api_search_location</responseType> <responseTime>2013-01-21 11:55:43</responseTime> <locations status="list"> <location name="60201040" title="Praterstern" municipality="Wien" type="stop" listIndex="0:1" coordName="wgs84" wgs84Lat="48.21815" wgs84Lon="16.39176" coordX="" coordY="" distanceMeter="" durationMinutes=""/> <location name="60201848" title="Praterstern/Lassallestra?e" municipality="Wien" type="stop" listIndex="1:2" coordName="wgs84" wgs84Lat="48.21962" wgs84Lon="16.39382" coordX="" coordY="" distanceMeter="" durationMinutes=""/> </locations> <message messageCode="1">ok</message> </response></ft>\[/code\]I have the following class "FtResponse" for all the four response types:\[code\]package model.response;import org.simpleframework.xml.Element;import org.simpleframework.xml.Root;@Root(name="ft")public class FtResponse { @Element private Response response; public FtResponse() { super(); } public FtResponse(Response response) { super(); this.response = response; } public Response getResponse() { return response; } public void setResponse(Response response) { this.response = response; } @Override public String toString() { return "FtResponse [response=" + response + "]"; }}\[/code\]And I have the class "Response". All the specific response classes inherit from this general class:\[code\]package model.response;import org.simpleframework.xml.Element;import org.simpleframework.xml.Root; @Root(name = "request") public class Response { @Element private Client client; @Element private String responseType; @Element private String responseTime; public Response() { super(); } public Response(Client client, String responseType, String responseTime) { super(); this.client = client; this.responseType = responseType; this.responseTime = responseTime; } public Client getClient() { return client; } public void setClient(Client client) { this.client = client; } public String getResponseType() { return responseType; } public void setResponseType(String responseType) { this.responseType = responseType; } public String getResponseTime() { return responseTime; } public void setResponseTime(String responseTime) { this.responseTime = responseTime; } @Override public String toString() { return "Response [client=" + client + ", responseType=" + responseType + ", responseTime=" + responseTime + "]"; } }\[/code\]This is one of my specific response classes:\[code\]package model.response;import org.simpleframework.xml.Element;import org.simpleframework.xml.Root;@Root(name = "response")public class SearchLocationStopsNearbyResponse extends Response { @Element private Client client; @Element private String responseType; @Element private String responseTime; @Element private LocationCentre locationCentre; @Element private Locations locations; @Element private Message message; public SearchLocationStopsNearbyResponse() { super(); } public SearchLocationStopsNearbyResponse(Client client, String responseType, String responseTime, LocationCentre locationCentre, Locations locations, Message message) { super(); this.client = client; this.responseType = responseType; this.responseTime = responseTime; this.locationCentre = locationCentre; this.locations = locations; this.message = message; } public Client getClient() { return client; } public void setClient(Client client) { this.client = client; } public String getResponseType() { return responseType; } public void setResponseType(String responseType) { this.responseType = responseType; } public String getResponseTime() { return responseTime; } public void setResponseTime(String responseTime) { this.responseTime = responseTime; } public LocationCentre getLocationCentre() { return locationCentre; } public void setLocationCentre(LocationCentre locationCentre) { this.locationCentre = locationCentre; } public Locations getLocations() { return locations; } public void setLocations(Locations locations) { this.locations = locations; } public Message getMessage() { return message; } public void setMessage(Message message) { this.message = message; } @Override public String toString() { return "SearchLocationStopsNearbyResponse [client=" + client + ", responseType=" + responseType + ", responseTime=" + responseTime + ", locationCentre=" + locationCentre + ", locations=" + locations + ", message=" + message + "]"; }}\[/code\]My problem is, that when i try to read in all the data to my nested classes i get the following exception:\[code\]org.simpleframework.xml.core.ElementException: Element 'locationCentre' does not have a match in class model.response.Response at line 7 at org.simpleframework.xml.core.Composite.readElement(Composite.java:527) at org.simpleframework.xml.core.Composite.readElements(Composite.java:445) at org.simpleframework.xml.core.Composite.access$400(Composite.java:59) at org.simpleframework.xml.core.Composite$Builder.read(Composite.java:1383) at org.simpleframework.xml.core.Composite.read(Composite.java:201) at org.simpleframework.xml.core.Composite.read(Composite.java:148) at org.simpleframework.xml.core.Composite.readVariable(Composite.java:623) at org.simpleframework.xml.core.Composite.readInstance(Composite.java:573) at org.simpleframework.xml.core.Composite.readUnion(Composite.java:549) at org.simpleframework.xml.core.Composite.readElement(Composite.java:532) at org.simpleframework.xml.core.Composite.readElements(Composite.java:445) at org.simpleframework.xml.core.Composite.access$400(Composite.java:59) at org.simpleframework.xml.core.Composite$Builder.read(Composite.java:1383) at org.simpleframework.xml.core.Composite.read(Composite.java:201) at org.simpleframework.xml.core.Composite.read(Composite.java:148) at org.simpleframework.xml.core.Traverser.read(Traverser.java:92) at org.simpleframework.xml.core.Persister.read(Persister.java:625) at org.simpleframework.xml.core.Persister.read(Persister.java:606) at org.simpleframework.xml.core.Persister.read(Persister.java:584) at org.simpleframework.xml.core.Persister.read(Persister.java:543) at org.simpleframework.xml.core.Persister.read(Persister.java:521) at org.simpleframework.xml.core.Persister.read(Persister.java:426) at TestRead.main(TestRead.java:19)\[/code\]I unterstood that Simple tries to find the element "locationCentre" in the class "Response", but there is no appropriate element. But how can I say to Simple, that it should choose the correct specific class, in this case "SearchLocationStopsNearbyResponse" depending on the XML response file?
