    Tks Phoenix, i have try someway as on the others thread, but it cann't work on me.
    Unfortunately for me, i reinstall zimbra on my computer, but now it's running well.

    Now i have integrated Ldap authentification between zimbra and alfresco, and then i installed zimlet on in order to i can save my attachment from zimbra to Alfresco.

    Both of integration running well, i can save my attachment on Alfresco from Zimbra.
    But, when i try to get attachment from Alfresco Document, i cann't get it.

    i get error log like bellow on alfresco

    HTML Code:
