• how call servlet class html form 2 answers

i have problems connecting html form servlet in web application. here's html file:

<form method="post" class="/login" action="/login">  		<fieldset class="textbox">  						                        <label class="textbox_field">                          <span>username or email</span>                          <input id="username" name="username" value="" type="text" autocomplete="on" placeholder="username">                        </label>                          <label class="textbox_field">                          <span>password</span>                          <input id="password" name="password" value="" type="password" placeholder="password">                        </label>                          <button class="submit_button" type="submit">sign-in</button>                  </fieldset>  </form>

and here servlet, called login:

 @webservlet("/login")     public class login extends httpservlet {         private static final long serialversionuid = 1l;      public login() {         super();     }      protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {         system.out.println("in dopost...");         response.setcontenttype("text/html;charset=utf-8");         printwriter out = response.getwriter();          string username = request.getparameter("username");         string pass = request.getparameter("password");          if(validate.checkuser(username, pass))         {             requestdispatcher rs = request.getrequestdispatcher("welcome");             rs.forward(request, response);         }         else         {            out.println("username or password incorrect");            requestdispatcher rs = request.getrequestdispatcher("index.html");            rs.include(request, response);         }     }  } 

i didn't edit web.xml file since "servlet 3.0, servlets can configured @webservlet annotation on class without need web.xml". correct me if misunderstood statement.

finally here's snippet project explorer, note home.jsp file form located:

note: sadly solutions provided in other similar questions on stackoverflow don't work in case.

you need replace input type button submit one.

<input type="submit" value="submit"/>
