[sunitha]

Hi ..

I am new to alfresco.I am trying to connect to the alfresco repository by using cmis api.
My program showing some errors at the atompub line..
could you people help me in regarding this area.
my source code..

import java.util.HashMap;
import java.util.Map;

import javax.xml.ws.BindingType;

import org.apache.chemistry.opencmis.client.api.Session;
import org.apache.chemistry.opencmis.client.api.SessionFactory;
import org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl;
import org.apache.chemistry.opencmis.commons.SessionParameter;


public class Third {
   
   public static void main(String arg[]) throws Exception{
      
      
      Map<String, String> parameter = new HashMap<String, String>();

      // Set the user credentials
      parameter.put(SessionParameter.USER, "admin");
      parameter.put(SessionParameter.PASSWORD, "admin");

      // Specify the connection settings
      parameter.put(SessionParameter.ATOMPUB_URL, "http://localhost:8070/alfresco/service/cmis");
      parameter.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());

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

      // Create a session
      SessionFactory factory = SessionFactoryImpl.newInstance();
      Session session = factory.getRepositories(parameter).get(0).createSession();
       System.out.println("Connected to repository:");
   }

}

Your code is not compiling for me ("root cannot be resolved").

I'm getting compilation error in this

 Folder newFolder = root.createFolder(newFolderProps); ‍

line.

[sunitha]

Hi..

for me that code was compiling but doesn't creating the folder..try to use the eclipse ide to run the program,follow the appropriate suggestions according to errors..code is running fine but folder is not creating by the program..


Thanks,
sunitha…

[muralidharand]

Hi Sunitha,

Don't use

 Folder newFolder = root.createFolder(newFolderProps); ‍

Use 

 Folder newFolder = session.getRootFolder().createFolder(newFolderProps); ‍

Get the root folder object from the session.getRootFolder();

Hope this helps you.

[muralidharand]

Hi Sunitha,
Do you want get these informations by using CMIS or webscript?

To get all the workflow instnaces.

api/workflow-instances?state={active|completed?}&initiator={authority?}&priority={priority?}&dueBefore={isoDate?}&dueAfter={isoDate?}&definitionId={workflow_definition_id?}&
    startedBefore={isoDate?}&startedAfter={isoDate?}&completedBefore={isoDate?}&completedAfter={isoDate?}&maxItems={maxItems?}&skipCount={skipCount?}&exclude={exclude?}
    <= SimpleWorkflowInstanceResponse[]

For more information : http://wiki.alfresco.com/wiki/Workflow_REST_API#Get_Workflow_Instance_Collection

To get all the task instnace.
api/task-instances?authority={authority_id?}&state={in_progress|completed?}&priority={priority?}&pooledTasks={true|false?}&
    dueBefore={isoDate?}&dueAfter={isoDate?}&properties={prop1, prop2, prop3…?}&maxItems={maxItems?}&skipCount={skipCount?}&exclude={exclude?}
    <= SimpleTaskInstanceResponse[]

Hope this helps you.

Hi,

try using
"http://localhost:8070/alfresco/cmisatom" instead of "…/service/cmis" … that was a problem for me.
