I saw in some tutorial/online material, that this classrg.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl will be helpful in accessing Aspects. Now, from the above exceptions, we see that this class is available in the following (0.3 version of this) library:

<dependency>
  <groupId>org.alfresco.cmis.client</groupId>
  <artifactId>alfresco-opencmis-extension</artifactId>
  <version>0.3</version>
</dependency>
‍‍‍‍‍‍‍

However, using the class (AlfrescoObjectFactoryImpl), expects TransientCmisObject class. Now both 0.12 and 0.13 versions of chemistry-opencmis-client-api/chemistry-opencmis-client-impl seem to not have this class at all.

Can you recommend a way to access Aspects and the values of the aspect properties of a document?

Thank you.

[mrogers]

The alfresco open cmis extension is obsolete and not needed since CMIS now contains the functionality to access "secondary types".

If you are insistent on using the alfresco-opencmis-extension then you need the version I fixed, as you have seen version 0.3 doesn't work with more recent versions of chemistry. 

I suggest you try version 1.0 instead which is available from nexus.alfresco.com

I am using chemistry-opencmis-client-api (version 0.13.0), chemistry-opencmis-client-impl (version 0.13.0). I believe 0.13.0 is the latest as of maven repository. So I believe, as we speak, this will have aspects in the secondary types.
In the admin node browser, I used the query (cmis-alfresco): SELECT * FROM cmis:document where cmis:name = 'river.JPG'
It returns an object, and clicking upon the link, I get values for all the properties of the aspect shown. I wonder what API and call the node browser uses. It is able to bring all the properties.

Following are some notable things that I see as a result of my query in the node browser…

Type   aslmo:lmodocument
Properties:
aslmo:lmo_microfiche_roll    d:text       false
aslmo:lmo_is_placeholder    d:boolean    false 
…

I am new to Alfresco development. I would like some help. I might find some in my search online.
In my custom model, I have a type defined, then defined an aspect with few properties, and them made this aspect as a mandatory-aspect of my type.

<model>
…
<types>
  <type name="aslmo:lmodocument">
    <title>…</title>
    <parent>cm:content</parent>
    
    <mandatory-aspects>
      <aspect>aslmo:documentProperties</aspect>
    </mandatory-aspects>
  </type>
</types>
<aspects>
  <aspect name="aslmo:documentProperties">
    <title>…</title>
    <properties>
      <property name="…">
        <title>…</title>
        <type>…</type>
      </property>
      …
    </properties>
  <aspect>
</aspects>
</model>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

My code looks as shown below; It is just a sample code, once I know how to do it, I need to develop our API:

Document object = (Document) cmisSession.getObjectByPath(path2Object);
List<Property<?>> properties = object.getProperties();
if (properties != null) {
  for (int index=0; index<properties.size(); index++) {
   Property aProperty = properties.get(index);
   log.info("\t P QueryName    [" + aProperty.getQueryName() + "]");
   log.info("\t P Value        [" + aProperty.getValueAsString() + "]");
  }
}

log.info("Secondary Types");
List<SecondaryType> secTypes = object.getSecondaryTypes();
if (secTypes != null) {
  for (int index=0; index<secTypes.size(); index++) {
   SecondaryType aspect = secTypes.get(index);
   log.info("\t ST QueryName          [" + aspect.getQueryName());
   log.info("\t ST Discription        [" + aspect.getDescription());
}
}

However, using the above code, does not bring anything for secondary types. And the properties list does not contain any from the aslmo kind.


Can you advise me towards the right direction?

For ppl with error in the title(NoClassDefFoundError: org/apache/chemistry/opencmis/client/api/TransientCmisObject), pls remove
parameter.put(SessionParameter.OBJECT_FACTORY_CLASS…
when the session is created… thanks @mrogers for the pointer…
