</li>

<li>
<input type="submit" name="register" id="register" value="Register"/>
<div class="clr"></div>

</ol>
</form>

response.setContentType("text/html");
PrintWriter out=response.getWriter();
String name=request.getParameter("username");
String email=request.getParameter("email");
String password=request.getParameter("password");

PreparedStatement stmt=con.prepareStatement("insert into users values(?,?,?)");
stmt.setString(1, name);

Have you register your RegisterServlet servlet in the web.xml file? and have you define a correct servlet-mapping too?
