xml binding - How to XML Bind an Apache Cayenne generated class -

first off, apologies long question.

i have number of classes generated cayenne such follows.

public abstract class _form extends cayennedataobject {      public static final string name_property = "name";     public static final string form_element_property = "formelement";     public static final string form_element1_property = "formelement1";     public static final string form_element2_property = "formelement2";      public static final string id_pk_column = "id";      public void setname(string name) {         writeproperty("name", name);     }     public string getname() {         return (string)readproperty("name");     }      public void addtoformelement(formelement obj) {         addtomanytarget("formelement", obj, true);     }     public void removefromformelement(formelement obj) {         removetomanytarget("formelement", obj, true);     }     @suppresswarnings("unchecked")     public list<formelement> getformelement() {         return (list<formelement>)readproperty("formelement");     } } 

i wish turn xml schema, preferably using bind notation. first thing note above code "_form.java" file, yet there generated "form.java" file extends class shown below. i'm aware "_form.java" (above) should not changed.

import forms.cayenne.persistent.auto._form;  public class form extends _form {  } 

in essence, wish convert this, , few other classes, xml have done in simple class example below, using xml bind.

import javax.xml.bind.annotation.xmlattribute; import javax.xml.bind.annotation.xmlelement; import javax.xml.bind.annotation.xmlrootelement;  @xmlrootelement(name = "form") public class form {      string name;     long id;      @xmlelement     public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }      @xmlattribute     public long getid() {         return id;     }      public void setid(long formid) {         this.id = formid;     } } 

what changes should making generated classes generate following xml?

<form id="1">     <name>test</name> </form> 

if need serialize xml form entity, no relationships, can use custom class generator templates. templates examples below cayenne 3.1. few customizations need:

1. create superclass template copying here , add jaxb annotations getters in attribute section (a loop starting '## create attribute set/get methods').

2. in custom sublcass template can add 'getid' method , '@xmlseealso' annotation referencing superclass. of course since allowed change subclass, can add manually, instead of customizing template. 'getid' may this:

   public int getid() { return cayenne.intpkforobject(this); }

3. then pick custom template class generator (be maven, ant or modeler). e.g. maven use 'supertemplate' parameter.

now if need more complex serialization (like do) includes various relationships, , differs request request same object, jaxb annotations limited that. , need write context sensitive jaxb marshaller or jax-rs messagebodywriter (if using jax-rs).
