unable to connect to the database,jsp servlet backend website

I have designed a web page which contains multiple forms and each form is provided with its unique submit button and are directed to different servlets on submission. But at a time only one is getting submitted successfully to the database and another form is not even getting directed to its servlets. How to do it?

<!-- UPDATE DONOR CARD-->

    <div class="col-xl-4 " style="opacity:0.9;">
          <div class="card bg-info text-center card-form mb-4">
            <div class="card-body">
              <h3 class="align-center">Update Donors Detail</h3>
              <p>Please fill out this form to update </p>
              <form action="UpdateHospitalController" method="post" name="update">
                <div class="form-group">
                  <input type="text" class="form-control form-control-lg" placeholder="Mobile no." id="mobNo" name="mobNo">
                </div>

                <div class="form-group">
                  <input type="text" class="form-control form-control-lg" placeholder="Date" id="datepickers" name="date">
                </div>


                <input type="submit" class="btn btn-dark btn-block" name="updateSubmit">
              </form>
            </div>
