Howto JSR 170 Document View import/export????

manuelgentile

I heard of JSR 170 Document View import/export in JSR Level 2 Podcast.
I try to make an action and import a xml content file and I had this error

Namespace URI "http://….." has not been registered with the repository

Why?
The document view imp/exp is not ready yet??

Thanks in advance

The document/system view import is available via the JCR api only at this time. The Import Action has not yet been integrated, therefore currently supports the Alfresco import format only.

That's my code…. what is wrong?

Session session=null;
try {
  session = repository.login(new SimpleCredentials("admin",
               "admin".toCharArray()));
  session.importXML("/", AddLomAction.class.getResourceAsStream("test.xml"),IMPORT_UUID_CREATE_NEW);
  session.save();
} catch (LoginException e) {
 e.printStackTrace();
} catch (RepositoryException e) {
 e.printStackTrace();
} catch (IOException e) {
 e.printStackTrace();
} finally {
  if (session!=null) session.logout();
}

Sorry david any news????

Thanks

manuelgentile

Excuse me but there is any news about this problem?

davidc

The repository does not support the nt:unstructured type (this is an optional type in JSR-170), therefore, it is necessary to define a model that represents your xml schema. The model also defines the namespaces as well.

You can find docs on model definition at http://wiki.alfresco.com/wiki/Data_Dictionary_Guide.

manuelgentile

Thanks David,
hovewer I think that a feature that allow to "convert/create" a alfresco content model starting from a XML Schema will sound good, isn't it?

There are some news about the feature for the definition of custom data type… (in data dictionary model)???

Thanks a lot!!!!

davidc

An XML schema to Content Model conversion (and vice versa) would indeed be useful. I'll add a JIRA feature request.

manuelgentile

Great news!!!!!!

manuelgentile

David are there any news in XML schema to Content Model conversion?

Thanks

manuelgentile

David,
with Jackrabbit I can obtain NodeTypeDefinition from XML Schema.
It's possible to use them in Alfresco?
Any suggestion?

Thanks

davidc

Not yet - the next version of the JCR Repository standard should include a common approach to defining Node Types and when we implement that you'll be able to import JCR type definitions.
