AW: JCR implementation: necessary steps for simple CMIS navigation

[Michael Mertins]

I remember I got no "rep:root" nodeType (used nt:base instead) and created a 
dummy JcrObjectId file:

package org.apache.chemistry.jcr;

import org.apache.chemistry.ObjectId;

public class JcrObjectId implements ObjectId{
    private String id; 
    
    public JcrObjectId (String id) {
        this.id = id;
    }
    /**
     * Gets the ID for this object.
     *
     * @return the object ID
     */
    public String getId()  {
        if (id == null) {
            id = "" ;
        }
        return this.id;
    }

}


Because I got the following error:

18:09:11,515 INFO  [TransientRepository] Session opened
18:09:11,515 ERROR [AbstractProvider] java.lang.UnsupportedOperationException
18:09:11,515 INFO  [ProviderHelper] Server error
