Ashok,

Which code are you trying to execute, which version of OpenCMIS are you using, and which version of Alfresco are you running against?

HI Jeff thank you very much for your reply,

I resolved this exception by adding some jar files. I am using your java client code(Alfresco cloud example) which is awesome. I am using alfresco cloud 3.2. And Jeff, one more thing In your example your getting list sites only, may I know how to get list of files inside document library belongs to particular site.

I am new to alfresco, I am using (https://code.google.com/p/alfresco-api-java-examples/source/browse/alfresco-cloud-example/src/main/java/com/alfresco/cloud/example/BaseJavaExample.java?spec=svn6eadbae1841997deed915784bf5e003e7d907656&r=6eadbae1841997deed915784bf5e003e7d907656) this code.

Everything in a documentLibrary folder belongs to the site the documentLibrary folder is sitting in. So if you have a reference to the documentLibrary folder, you can walk the tree until you get to the site folder. Conversely, if you want to find the documents for a particular site, you can get the site's documentLibrary folder and then either traverse the folder hierarchy or use getDescendents or a query with IN_TREE.

Thank you Jeff, I got list of folders inside that documentLibrary, but every time I am looping to get subfolders. is this only way to get subfolders? can't we get all subfolders in a single string(folder1/folder2/file.jpg) ?.

Thank you,
Ashok

You can use CMIS query language to select sub folders of your site's documentLibrary
First get your site documentLibrary folder


   AlfrescoFolder docLib = (AlfrescoFolder) session.getObjectByPath("/sites/{site short name}/documentLibrary");
‍‍‍

Then Select all subfolders


Then select all subfolders 
   String sql = "SELECT * FROM cmis:folder WHERE IN_TREE('"+docLib.getId()+"')";
   ItemIterable<QueryResult> rs = session.query(sql, false);
‍‍‍‍‍

Then you can get all folder properties include cmisath.

I Fixed it by adding chemistry-opencmis-client-impl-0.13.0.jar to project

Please provide:
- The version of Alfresco
- The service URL
- The version of OpenCMIS you are using

The TransientCmisObject was removed from Chemistry some time ago. Any classes using it will need to be updated.

In particular if you are using the alfresco-opencmis-extension then you need a more recent version of the alfresco extension for the current versions of Chemistry or use the old alfresco-opencmis-extension with a an older version of Chemistry. Can't remember what versions are compatible but I fixed the alfresco-opencmis-extension (removed the need for TransientCmiSObject) a couple of years ago, IIRC before the release of 5.0.

Also IIRC the extension was hosted on google code which no longer allows versions to be created. I think the extension is available from alfresco's maven.
