Subject: property acess type error in orm.xml descriptor
Hi, persistence guys~
During testing persistence examples through orm.xml, I got error regarding property access type.
The entity class has no annotations, all mappings are declared in orm.xml.
The access type is declared as PROPERTY explicitly.
public class Person implements java.io.Serializable {
String _name;
String _address;
public Person(){
}
public Person(String name){
this._name = name;
}
public String getName() {
return _name;
}
public void setName(String name) {
this._name = name;
}
public String getAddress() {
return _address;
}
public void setAddress(String address) {
this._address = address;
}
public String toString(){
return "Person: {"+"(name = "+_name +", address = " + _address + ")}";
}
}
<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings xmlns="
http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd" version="1.0">
<entity name="Person" class=" com.sun.s1asdev.ejb.ejb30.persistence.ormdesc.par.Person" access="PROPERTY" >

<attributes>
<id name="name">
<column name="NAME"/>
</id>
<basic name="address">
<column name="ADDRESS"/>
</basic>
</attributes>
</entity>
</entity-mappings>
When I deploy the application following error occurs.
Exception [TOPLINK-7216] (Oracle TopLink Essentials - 2006.4 (Build 060420)): oracle.toplink.essentials.exceptions.ValidationException

It seems to me that MetadataHelper.getClassForAttribute() has some assumption - corresponding field exists for the attribute. So it does Class.getField() to identify the type of attribute. I think it is incorrect assumption in this entity case.
I attach test sources, it can be unzipped into appserv-tests/devtests/ejb/ejb30/persistence and run as other tests.
If this is a bug, it seems to me serious bug - very basic behaviour though descriptor fails....-.-;
