Gets values from Aspects

[Chad S]

Hello,

WARNING: I'm a newbie. That has been trying/Googling to get data out
of aspects. Using the AlfrescoDocument. Has fixed the problem of
seeing the aspects. But I still can't seem to get data out of them.

What I am trying to do is use Apache Chemistry's OpenCMIS to get data
out of Alfresco.

I created a standard HTML content document. (Which I have the object
Id specified in my query String below.) Added aspects, namely the
Taggable. And added a tag.

I've been trying different things for the past week. And am completely
stuck. Any help, guidance, assistance is greatly appreciated!

Here is my code:
<code>
package org.apache.chemistry.opencmis.doc;

import java.util.HashMap;
import java.util.Map;
import org.alfresco.cmis.client.AlfrescoDocument;

import org.apache.chemistry.opencmis.client.api.Property;
import org.apache.chemistry.opencmis.client.api.QueryResult;
import org.apache.chemistry.opencmis.client.api.Session;
import org.apache.chemistry.opencmis.client.api.SessionFactory;

import org.apache.chemistry.opencmis.commons.SessionParameter;
import org.apache.chemistry.opencmis.commons.enums.BindingType;

/**

public class AlfrescoCMISConnector {

public static void main(String args[]) {
Map<String, String> parameter = new HashMap<String, String>();

// user credentials
parameter.put(SessionParameter.USER, "cshryock");
parameter.put(SessionParameter.PASSWORD, "dRnkc0k3");

// connection settings
parameter.put(SessionParameter.ATOMPUB_URL, "http://
app.g3rdmedia.com:8080/alfresco/service/cmis");
parameter.put(SessionParameter.BINDING_TYPE,
BindingType.ATOMPUB.value());

// set the object factory
parameter.put(SessionParameter.OBJECT_FACTORY_CLASS,
"org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");

// create session
SessionFactory factory = SessionFactoryImpl.newInstance();
Session session =
factory.getRepositories(parameter).get(0).createSession();

String query = "SELECT d.* FROM cmis:document AS d WHERE
d.cmis:objectTypeId = 'D:pdl:person'";

query = "SELECT d.* FROM cmis:document AS d WHERE
d.cmis:objectId = 'workspace://SpacesStore/7b68ff5b-7a80-43cc-
ba75-256191c7654c'";

ItemIterable<QueryResult> result = session.query(query,
false);

print("Quering for: " + query);
print("Found: " + result.getTotalNumItems() + " Items");

printSeperator();

for(QueryResult item : result) {

// Load document
AlfrescoDocument doc = (AlfrescoDocument)
session.getObject(item.getPropertyByQueryName("d.cmis:objectId").getFirstValue().toString());

print("PROPERTIES:");
for (Property<?> prop : doc.getProperties()) {
print(" " + prop.getDisplayName() + " (" +
prop.getId() + "): " + prop.getFirstValue());
}

print("");
print("TRY TO GET TAGGABLE DATA:");
Property<Object> p = doc.getProperty("cm:taggable");
print(doc.getProperty("cm:taggable").toString());

System.out.println(session.getObject(p.getFirstValue().toString()));

print("");
print("ASPECTS:");
for (ObjectType aspect : doc.getAspects()) {
print(" " + aspect.getDisplayName() + "(" +
aspect.getId() + ")");
for (ObjectType ac : aspect.getChildren()) {
print(" > " + ac.getDisplayName() + "(" +
ac.getId() + ")");
}
}

printSeperator();
}
}

private static void print(String s) {
System.out.println(s);
}

private static void printSeperator() {
System.out.println("");
System.out.println("-----");
System.out.println("");
}
}

This is the exception I get in the console:

Again thanks for your assistance.

[Florian Müller]

Hi Chad,

The cause of the exception you are seeing is that tag objects are not exposed through CMIS. When you call getObject() with a tag NodeRef, it can't find a matching CMIS type and throws this exception.

Alfresco 3.4.3 supports querying for tags [1]. You can also get, set and remove tags via the cm:taggable aspect but you have to provide tag NodeRefs. Unfortunately, there is currently no way through CMIS to get hold of the names of the tags.

[Andy Ingham]

Hi Florian,

Do you know if CMIS (Alfresco) is now capable of allowing the retrieval of tag names? Hopefully things have moved on in those 2 years!

Many thanks,

Andy
