java - JAXB @XmlElementWrapper ArrayList size zero -

i have xml load jaxb. load correctly, except geteffectsettings() size 0 when should show 2 because have 2 'effect-setting' in 'settings-list' element. ideas? i'm able load , print effect's target attribute , effects shown should except variable.

the xml:

effect.java: package com.morethanheroic.swords.effect.domain;

import javax.xml.bind.annotation.*; import java.util.arraylist;  @xmlaccessortype(xmlaccesstype.field) public class effect {      @xmlattribute     private string target;      @xmlelementwrapper(name = "settings-list")     @xmlelement(name = "effect-setting")     private arraylist<effectsetting> effectsettings;      public string gettarget() {         return target;     }      public arraylist<effectsetting> geteffectsettings() {         return effectsettings;     } } 

effectsetting.java:

package com.morethanheroic.swords.effect.domain;  import javax.xml.bind.annotation.xmlaccesstype; import javax.xml.bind.annotation.xmlaccessortype; import javax.xml.bind.annotation.xmlelement;  @xmlaccessortype(xmlaccesstype.field) public class effectsetting {      @xmlelement(name = "setting-name")     private string name;      @xmlelement(name = "setting-value")     private string value;      public string getname() {         return name;     }      public string getvalue() {         return value;     } } 

the unmarshaller use this:

package com.morethanheroic.swords.definition.service;  import org.springframework.beans.factory.annotation.autowired; import org.springframework.context.applicationcontext; import org.springframework.stereotype.service; import org.xml.sax.saxexception;  import javax.xml.xmlconstants; import javax.xml.bind.jaxbcontext; import javax.xml.bind.jaxbexception; import javax.xml.bind.unmarshaller; import javax.xml.validation.schema; import javax.xml.validation.schemafactory; import java.io.file; import java.io.ioexception; import java.util.arraylist; import java.util.list;  @service public class xmldefinitionloader {      private static final schemafactory schemafactory =  schemafactory.newinstance(xmlconstants.w3c_xml_schema_ns_uri);      @autowired     private applicationcontext applicationcontext;      public list loaddefinitions(class clazz, string resourcepath, string schemapath) throws jaxbexception, ioexception, saxexception {         return unmarshalltargetfiles(buildunmarshaller(clazz, schemapath), gettargetfiles(resourcepath));     }      private arraylist unmarshalltargetfiles(unmarshaller unmarshaller, file[] files) throws jaxbexception {         arraylist list = new arraylist<>();          (file file : files) {             list.add(unmarshaller.unmarshal(file));         }          return list;     }      private file[] gettargetfiles(string resourcepath) throws ioexception {         return applicationcontext.getresource(resourcepath).getfile().listfiles();     }      private unmarshaller buildunmarshaller(class clazz, string schemapath) throws ioexception, saxexception, jaxbexception {         unmarshaller unmarshaller = jaxbcontext.newinstance(clazz).createunmarshaller();         unmarshaller.setschema(buildschema(schemapath));          return unmarshaller;     }      private schema buildschema(string schemapath) throws ioexception, saxexception {         return schemafactory.newschema(applicationcontext.getresource(schemapath).getfile());     } } 

and how try access effects:

@postconstruct public void init() throws exception {     list<rawitemdefinition> rawitemdefinitionlist = xmldefinitionloader.loaddefinitions(rawitemdefinition.class, "classpath:data/item/definition/", "classpath:data/item/schema.xsd");      (rawitemdefinition rawitemdefinition : rawitemdefinitionlist) {         if(rawitemdefinition.geteffectlist() != null) {             system.out.println("effect: "+rawitemdefinition.geteffectlist().get(0).gettarget());             system.out.println("effect: "+rawitemdefinition.geteffectlist().get(0).geteffectsettings().size());         }          itemdefinitionmap.put(rawitemdefinition.getid(), new itemdefinition(rawitemdefinition));     } } 

could provide code call geteffectsettings() , how unmarshalling done (by hand or framework ?).

update

have tried adding @xmlrootelement effectsetting class ?

update 2

as found yourself, check packages of classes :

the effect , effectsetting in other package rawitemdata , added package-info.java rawitemdata's package. after adding effect's package it's started working.
