try this within jsp to pop show message after inserting value into db

<%
String s1=request.getParameter("username");
String s2=request.getParameter("passward");
int a=0;
try{
     a=st.executeUpdate("insert into tablename values('"+s1+"','"+s2+"')");
if(a==1){

        %>
        <p>well come for you</p>
        <%
        }
        else{
            %>


            <p>not well come for you</p>
    <%  }
    }

}catch(Exception e){
    e.printStackTrace();
}

%>

after data insert in DB you need to use 

request.setAttribute("alertMsg", "data add sucess");

then redirect to jsp by using RequestDispatcher

RequestDispatcher rd=request.getRequestDispatcher("/index.jsp");  
rd.include(request, response);

Now in jsp use scriptlet tag like

<% String message = (String)request.getAttribute("alertMsg");%>

And you will get a alert message.

Now in javascript alert show like this

<script type="text/javascript">
    var msg = "<%=message%>";
    alert(msg);
</script>
