Bootstrap tabs containing different forms

I have 2 bootstrap tabs in my html page, each containing different forms. Form Action has been specified to the same jsp page.

When I am submitting a form from 2nd tab, the whole page is getting reloaded, and page sets 1st tab active as it is set by default.

What can I do to avoid this? When I submit form from 2nd tab, I want the same page but the second tab active as it should be.

<div class="container">
                <ul class="nav nav-tabs" id=passengerTabs>
                        <li role="presentation" class="active"><a data-toggle="tab"
                                href="#searchbyflight">Search By Flight Number</a></li>
                        <li role="presentation"><a data-toggle="tab"
                                href="#searchbypassenger">Search By Customer Name</a></li>
                </ul>
                <div class="tab-content">
                        <div class="container tab-pane fade in active" id="searchbyflight">
                                <form class="form-inline" method="get" action="PassengerDetails.jsp">
                                        <div class="form-group">
                                                <input type="text" class="form-control" id="textFlightNumber"
                                                        name="textFlightNumber">
                                        </div>
                                        <button type="submit" class="btn btn-primary"
                                                id="searchflightnumber">Search Customers</button>
                                </form>

                                <form class="form-inline" method="get" action="">
                                        <div class="form-group">
                                                <input
                                                        type="text" class="form-control" id="textCustomerName"
                                                        name="textCustomerName">

                                </form>
