    Hi

    I am successful in the following operations
    - connecting to the server
    - adding the server certificate to the client trustmanager dynamically (without user intervention - that is the requirement here)
    - logging into the server
    - getting the details of the current working directory

    But thereon... any other operation fails with the above exception. Is
    it something to to do with the SSLSession. Do I have to do something
    on the session?

    Thanks again

    SV

    Hi Could you please share details regarding how did the connection with Server worked as I am facing similar issue . Please see error stack trace
