not able to create folder using CMIS API

Hi,

I am building one client application which is integrated with alfresco using external authentication. I am able to create a session with alfresco using current user alf_ticket. Now in root folder i have created one folder with the name "test".

Now i want to create folder inside the folder test with the name of the current user.

For this i written the below code:

private static Folder createFolder(Folder target,String newFolderName){

		Map<String, String> props =new HashMap<String, String>();

		props.put(PropertyIds.OBJECT_TYPE_ID,"cmis:folder");

		props.put(PropertyIds.NAME,"abc");

		Folder newFolder = target.createFolder(props);
return newFolder;
}
 
 

and now calling this method in main after retriving the test as below:

Folder target =(Folder) session.getObject("workspace://SpacesStore/898583d0-5c38-4dad-a297-204f45960a4c");//retrieving test folder

					Folder newFolder = createFolder(target,"abc");

but while running this code this is giving me org.apache.chemistry.opencmis.commons.exceptions.CmisPermissionDeniedException: Forbidden error.

Please help me with this.

Regards,
Nancy
