Hi again,
as suggested in my previous post, I left the OCM annotations way to
follow the XML mapping one but I always got a lot of errors.
The wish is the same: have two POJOs, Type and Element so an element
instance have a reference to it's type.
Errors are:
- org.xml.sax.SAXParseException: Document root element "jackrabbit-ocm",
must match DOCTYPE root "null"
- "Unknown mixin type ocm:discriminator for mapped class class
com.imnet.oam.cm.Type; nested exception is
javax.jcr.nodetype.NoSuchNodeTypeException:
{http://jackrabbit.apache.org/ocm}discriminator";
Java classes are really simple, just two "beans":
public class Type {
private String path;
private String uuid;
private String name;
private String description;
// Getters and setters follows...
}
public class Element {
private String path;
private String uuid;
private String name;
private String description;
private Type type;
// Getters and setters follows...
}
Here is my XML mapping file:
<?xml version="1.0" encoding="UTF-8"?>
<jackrabbit-ocm>
<class-descriptor className="Type" jcrType="my:type"
jcrSuperTypes="nt:base" jcrMixinTypes="mix:referenceable">
<field-descriptor fieldName="path" path="true"/>
<field-descriptor fieldName="uuid" uuid="true"/>
<field-descriptor fieldName="name" jcrName="my:name"
jcrMandatory="true"/>
<field-descriptor fieldName="description" jcrName="my:description"/>
</class-descriptor>
<class-descriptor className="Element" jcrType="my:element"
jcrSuperTypes="nt:base" jcrMixinTypes="mix:versionable">
<field-descriptor fieldName="path" path="true"/>
<field-descriptor fieldName="uuid" uuid="true"/>
<field-descriptor fieldName="name" jcrName="my:name"
jcrMandatory="true"/>
<field-descriptor fieldName="description" jcrName="my:description"/>
<bean-descriptor
fieldName="type"
jcrName="my:type"
proxy="false"
jcrType="my:type"
jcrMandatory="true"
jcrOnParentVersion="IGNORE"
converter="org.apache.jackrabbit.ocm.manager.beanconverter.impl.ReferenceBeanConverterImpl"
/>
</class-descriptor>
</jackrabbit-ocm>
The application main methods registers all needed namespaces ("ocm",
"my", etc...), instantiates a new ObjectContentManagerImpl
(successfully) and tries to do something like this:
Type type = new Type()
type.setPath("/bar")
type.setName("Bar");
type.setDescription("A bar");
ocm.insert(type); <-- This throws a
ocm.save();
Element element = new Element()
element.setPath("/foo")
element.setName("Foobar");
element.setDescription("Foo bar");
element.setType((Type) ocm.getObject("/bar"));
ocm.insert(element);
ocm.save();
I really have no other ideas, I hope in yours... thank you!
