Hi all,

I want to specify my mappings in orm.xml, instead of via annotations.

I'm using:
    hibernate 3.2.0.cr2
    hibernate-annotations 3.2.0.cr1
    hibernate-entitymanager 3.2.0.cr1

Here is my orm.xml file:
Code:
<?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 http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"
               version="1.0">


  <entity class="bar.foo.Person">
    <attributes>
      <id name="id"/>
      <basic name="firstName"/>
      <basic name="lastName"/>
    </attributes>
  </entity>
</entity-mappings>

The problem is that HB -apparently- tries to validate the file, but cannot find the DTD.
Here is the exception:
Code:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'entity-mappings'.
   at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:236)

   at org.dom4j.io.SAXReader.read(SAXReader.java:465)
   at org.hibernate.cfg.AnnotationConfiguration.addInputStream(AnnotationConfiguration.java:563)


I cannot to save my life figure out the right values for xmlns, xmlns:xsi, and xsi:schemaLocation in orm.xml.

Could somebody please post a sample orm.xml that works with the latest HB?

Thank you,

Susie.

Hi again,

An I the only one trying to move from annotations to the now supported orm.xml mapping file?
I checked the docs and forum, and it seems that not very many people are switching.

Thanks,

Susie.

Ha, I found an example of a working orm.xml file at http://blog.hibernate.org/cgi-bin/blosx ... tojpa.html.

But now, I'm getting the following exception:

Code:

Caused by: org.hibernate.AnnotationException: Cannot override an property with <id> it does not have an @Id already
   at org.hibernate.reflection.java.EJB3OverridenAnnotationReader.getId(EJB3OverridenAnnotationReader.java:919)

   at org.hibernate.ejb.Ejb3Configuration.createEntityManagerFactory(Ejb3Configuration.java:205)
   ... 29 more

Here is the bean I'm trying to map:
Code:
public class Person
{

  public Long id;

  public String firstName;
  public String lastName;

If I annotate the id field with '@Id @GeneratedValue' , it works.

I don't get it. The point of the mapping file is to not have annotations. Why this exception?

Thanks,

S.

I found what the probelm was: I need to add metadata-complete="true" to the <entity tag:
Code:
<entity class="foo.bar.Person" metadata-complete="true">

Don't worry, you're not the only one who prefers xml over annotations :)

Code:
  <persistence-unit-metadata>
    <xml-mapping-metadata-complete/>
  </persistence-unit-metadata>

P.S. Is your name really Susie Derkins?

Hi Susie.
I expect very few people using orm.xml rather than annotations. Like Checked/Runtime exceptions, the war is going to be over soon :-)

However, I'm really interested in your feedback (both on documentation and bug report). Feel free to contact me directly on those. I know my documentation suck in this area.

i'm interested to Merge annotation and orm mapping...
i have automatically generated pojo & dao & interfaces for ejb3... but i like a way to add custom query not hard-coded...
i mean.. like store procedures... i like to have a "login" named query in orm.xml so i can modify it without modify the code & recompile....
or.. even better... i hope without even shut down application!!!
