Creating a folder with DFC (Documentum)

Question

I'm facing a strange problem. All I want is to create a new folder with the DFC. But when I execute the code (JUnit or inside the Application) no folder is created and surprisingly no exception is thrown. So I guess the error is somewhere else.

This is my code:

public void createNewFolder(String sFolderName, String sParentId)
{
    IDfSession session = null;
    try 
    {
        session = getSession();     
        IDfFolder newFolder = (IDfFolder) session.newObject("dm_folder");
        newFolder.setObjectName(sFolderName);
        newFolder.link(sParentId);
        newFolder.save();
        String sDump = newFolder.dump();

        System.out.println("Folder ["+sFolderName+"] saved.");
        System.out.println("Folder has id ["+newFolder.getId("r_object_id")+"]");
    }
    catch (DfException e) 
    {
        e.printStackTrace();
    }
    finally
    {
        m_sessionManager.release(session);
    }

I'm getting a sysobject id in return, but when I'm trying to fetch it with a dql statement then I cannot find it.

I tried to execute a dql create query alternatively which creates the folder. This does not work with JUnit or in the running Application, but when I execute it manually it simply works.

This is my getSession() method

private IDfSession getSession()
{
    try 
    {
        if (m_sessionManager == null)
        {
                return establishConnection();
        }
        else
        {
            return m_sessionManager.getSession(m_sRepository);
        }
    } 
    catch (DfException e) 
    {
        e.printStackTrace();
    }
    return null;
}

Any ideas on that?

Thanks to the comments of unicron. This actually let me fix the problem. In my establishConnection() method, which I did not post in the question, I actually used beginTransaction(). Removing that fixed the problem and everything worked fine.

public IDfSession establishConnection(String sUserName, String sPassword, String sRepository) throws DfException 
{
    System.out.println("Login");
    IDfClientX clientX = new DfClientX();

    IDfClient localClient = clientX.getLocalClient();
    IDfSessionManager sessionManager = localClient.newSessionManager();
    IDfLoginInfo loginInfo = new DfLoginInfo();
    loginInfo.setUser(sUserName);
    loginInfo.setPassword(sPassword);
    sessionManager.setIdentity(sRepository, loginInfo);

// THIS IS THE EVIL LINE !
    sessionManager.beginTransaction();

    System.out.println("sessionmanager ist geladen");
    IDfSession session = sessionManager.getSession(sRepository);
    m_sUserName = sUserName;
    m_sRepository = sRepository;
    m_sessionManager = sessionManager;

    return session;
}

Which user you are using when you try folder creation with DFC? Is it the same one you're using later for DQL checking? If not, it could be that folder's ACL doesn't let you see newly created folder with different user.
