Why am I getting a "Type is unknown" error in Alfresco?

Question

I’m having problem while adding document with custom aspects (Alfresco 4.2e). It shows the following error:

Exception in thread "main" org.apache.chemistry.opencmis.commons.exceptions.CmisObjectNotFoundException: Type 'kb:referencable' is unknown!

Any help would be much appreciated.

These are my files:

sample.java

Map<String, String> props = new HashMap<String, String>();
    props.put(PropertyIds.NAME, newDocName);
    props.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document,kb:referencable");
    props.put("kb:documentRef", "My document");
    String content = "sample=================" ;
    byte[] buf = null;
    try {
        buf = content.getBytes("UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    ByteArrayInputStream input = new ByteArrayInputStream(buf);
    ContentStream contentStream = session.getObjectFactory()
            .createContentStream(newDocName, buf.length,
                    "text/plain; charset=UTF-8", input);
    target.createDocument(props, contentStream, VersioningState.MAJOR);

Answer 1

It's an old ticket, but I'll answer it.

As object type you'll need to fill in the prefix of the CMIS type.

• D: for document
• F: for folder
• P: for Aspect

In CMIS 1.1 you can add (in your case an Aspect) as cmis:secondaryObjectTypeIds or SECONDARY_OBJECT_TYPE_IDS and prior to 1.1. as cmis:objectTypeId or OBJECT_TYPE_ID
