Internal Server Error

Folder not found: /st:testuserone (in workspace://SpacesStore/329bbf25-9ebb-4f47-845c-ddb16dd15852)

commons-httpclient-3.1.jar

commons-io-2.4.jar

and let me know can possible to retrieve list of file(link to download) from any one directory(folder)

I believe your code will not work because of the url you are creating is not right.

Please, take a look at this one, which is the right one, generated by Share when you click the Download action:

http://localhost:8081/share/proxy/alfresco/slingshot/node/content/workspace/SpacesStore/60bcd2b9-73f...caca/Especifica%c3%a7%c3%a3o_T%c3%a9cnica_OS207.pdf?a=true

One idea is to try to find in Share's source code the part responsible for generating the url.

Thank you doug.

String url = "http://127.0.0.1:8090/share/proxy/alfresco/slingshot/node/content/workspace/SpacesStore/a22bb988-84e...";  eventhough its getting 401 Unauthorized ... 

if that workspace contains same filename then how can i differentiate. like folder or directories

Why not use apache chemistry openCMIS library?

[nareshvy]

I was Tried that also it getting ContentServiceSoapBindingStub getContentService error ... please send the link example program for download

[kaynezhang]

import org.apache.chemistry.opencmis.client.api.*

public Session getSession()

{
String serverUrl = "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom";
String userName = "admin";
String password = "admin";

SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
Map<String, String> params = new HashMap<String, String>();
params.put(SessionParameter.USER, userName);
params.put(SessionParameter.PASSWORD, password);
params.put(SessionParameter.ATOMPUB_URL, serverUrl);
params.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
params.put(SessionParameter.OBJECT_FACTORY_CLASS,
"org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");
List<Repository> repos = sessionFactory.getRepositories(params);
if (repos.isEmpty()) {
throw new RuntimeException("Server has no repositories!");
}

return repos.get(0).createSession();
}

public void downloadCotent()

{

Session session = getSession();

try {
Document document = (Document)session.getObjectByPath( "/sites/testuserone/documentLibrary/Test") ;
InputStream stream = document.getContentStream().getStream();
....

} catch (Exception e) {
// TODO Auto-generated catch block
