Hi,
I'm new to the OpenCMIS Java API. I got errors when trying to retrieve
an object (a folder) with some properties with custom extensions. But I
can retrieve normal CMIS objects without custom properties without any
problem.
Here is the error message:
Exception in thread "main"
org.apache.chemistry.opencmis.commons.exceptions.CmisRuntimeException:
Property 'dc:issued' doesn't exist!

Java Result: 1
My code where the error was thrown:
... // build a session object ...
SessionFactory f = SessionFactoryImpl.newInstance();
Map<String, String> parameter = new HashMap<String, String>();
parameter.put(SessionParameter.USER, user);
parameter.put(SessionParameter.PASSWORD, passwd);
parameter.put(SessionParameter.ATOMPUB_URL, url);
parameter.put(SessionParameter.BINDING_TYPE,
BindingType.ATOMPUB.value());
parameter.put(SessionParameter.REPOSITORY_ID, "content");
Session session = f.createSession(parameter);
CmisObject obj = session.getObject(objId); // error thrown!!!
...
Is it because the server is not set up correctly or do I need to some
extra coding on the client side for objects with custom properties? I
can use the Python API to retrieve the object without any problem. Here
is what python code would retrieve:
cmis:objectId: L3JlcS90ZXN0L0swMDAyNjguMDAw

Apparently there exists an "dc:issued" property. so I am guess it's the
client Java code. Any ideas?
Thank you very much!
