OCM: JcrMappingException Exception: Unknown mixin type ocm:discriminator
Hi, all! Hi, Christophe!
I`m trying to write simple working OCM tesbed for my evil purposes :)
I stealed ideas and RepositoryUtils from test suite and my setup is:
System.out.println("registering repository ... ");
RepositoryUtil.registerRepository(reponame,
"./src/conf/repository.xml", "./repository");
Repository rep = RepositoryUtil.getRepository(reponame);
Session ses = RepositoryUtil.login(rep, user, password);
//registers OCM namespace
RepositoryUtil.setupSession(ses);
I got exception about node types and I suppose it happend because I do not registered needed node types.
Could you please point me which xml file to use or which piece of code from test I can steal to get rid of exception.
Exception:

I agree with you. We have to simplify this step.

Hi again, Christophe!
Thanks, simple test works now after stealing registerNodeTypes() from some tests.
Well, may be it's good idea to make such system node types and namespaces registration automated?
It is not trivial for regular user to dig it all from tests, cut, paste and register things that must just work.

Alex,
The node type "ocm:discriminator" is missing in the jcr repository. here is
the definition :
<nodeType name="ocm:discriminator" isMixin="true">
<supertypes>
<supertype>nt:base</supertype>
</supertypes>
<propertyDefinition name="ocm:classname" requiredType="String"
autoCreated="false" mandatory="true" onParentVersion="COPY"
protected="false" multiple="false" />
</nodeType>
It is used to store the class name for some mapping strategy. For example,
when you map an class into the node type nt:unstructured, it is necessary to
store the classname in order to instantiate the object correctly during a
retrieve. .
