    Ora-12541 tns:no listner form10g with oracle 11g

    Hi, I installed oracle 11g r2 in windows 7 platform.
    later I installed oracle developer suite r2. It was installed successfully.
    But If I try to connect to oracle 11g database from developer suite form builder
    it is giving the ORA-12541 TNS:NO LISTNER error.
    I checked the listner status and it is running.
    plz suggest the solution

    with thanks
