Thanks for your response. Made changes to MyHashMapAdapter.java the format I
needed but still no luck.
I am trying to get output in this format.
<xml>
<abc>
<123></123>
<345></345>
</abc>
<def>
<789></789>
</def>
</xml>
MyBean.java
private Map<String,List<String>> valueMapList=null;
@XmlJavaTypeAdapter(MyHashMapAdapter.class)
@XmlElement
public Map<String, List<String>> getValueMapList() {
return valueMapList;
}
public void setValueMapList(Map<String, List<String>> valueMapList) {
this.valueMapList = valueMapList;
}
MyHashMapAdapter.java
public class MyHashMapAdapter extends
XmlAdapter<HashMap<String,List<String>>, Map<String,List<String>>> {
@Override
public HashMap<String,List<String>> unmarshal( String[] value ) {
HashMap<String,List<String>> m = new HashMap<String,List<String>>();
return m;
}
@Override
public String[] marshal(List<String> arg0) throws Exception {
String[] s = (String[]) arg0.toArray();
return s;
}
}
