getParamter（）返回NULL

Question

Why is request.getParameter("termin"); returning NULL .The Connection and the Statement for my Databse are correct.It works fine in an more simple Version. This is JSp/JAva Code:

int result = 0;
if(request.getParameter("submit") != null) {
    String name = new String();

    if(request.getParameter("termin") != null) {
        name = request.getParameter("termin");

    }else {
        out.println("termin is null");
    }
    Termin t1 = new Termin();
    result = t1.setTermin(name);

Here is the HTML Code :

<form action="index.jsp" method="POST" name="test">
    <div class="modal fade" id="bModal" tabindex="-1" role="dialog" aria-labelledby="beispielModalLabel" aria-hidden="true">

        <div class="modal-dialog">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Schließen</span></button>
                    <h4 class="modal-title" id="beispielModalLabel">Neuer Termin</h4>
                </div>
                <div class="modal-body">
                    <!-- <form role="form" action="index.jsp" method="POST"> -->
                        <div class="form-group">
                            <label for="empfaenger-name" class="control-label">Name</label>
                            <input type="text" class="form-control" id="empfaenger-name" name="termin" value="">
                        </div>
                        <div class="form-group">
                            <label for="nachricht-text" class="control-label">Zusätzlich:</label>
                            <textarea class="form-control" id="nachricht-text"></textarea>
                        </div>
                    <!--  </form> -->
                </div>
                <div class="modal-footer">          
                    <button type="button" class="btn btn-danger" id="del" data-dismiss="modal" >Löschen</button>
                    <input type="submit" name="submit" class="btn btn-primary" id="eintrag" data-dismiss="modal" value="Speichern" >
                </div>
            </div>
        </div>

    </div>
</form>

I'm not a Bootstrap expert yet I can see a few potential causes to this issue:

• data-dismiss="modal" - looking at: http://getbootstrap.com/javascript/#modals-related-target it seems that data-dismiss="modal" is used only with "close" buttons - never with "submit"!

• the class class="btn btn-primary" is supposed to be used with elements of type button and you're using it with input

• using the id attribute might create a conflict with bootstrap autogenerated html-elements, but I'm just guessing here based on your comment above.
