404 error while redirecting to html from a servlet
0
I have a problem with a school project, it's a little web dinamic project.
In the Login page, if I submit parameters of a user that exist in my DB, all goes well and I have my "success.html" page, but if I submit parameters of a user that is not in my DB I have a 404 page, while I'm expecting my "failure.html".
Could u please help me to find the error?
I'm using:
- Eclipse Java Neon
- Tomcat 9.0.12
This is my login form:
<form id="login" class="form-horizontal" action="/IROPLAS/Controller/LoginServlet" method="GET">
<div class="form-group">
<label class="control-label col-xs-8 col-sm-4 col-md-5" for="mail">E-mail:</label>
<div class="col-xs-10 col-sm-8 col-md-4">
<input type="text" class="form-control" id="mail" name="mail" placeholder="E-mail">
</div>
</div>
<div class="form-group">
<label class="control-label col-xs-8 col-sm-4 col-md-5" for="pw">Password:</label>
<div class="col-xs-10 col-sm-8 col-md-4">
<input type="password" class="form-control" id="pw" name="pw" placeholder="Password">
</div>
</div>
<br>
<button type="submit" class="btn btn-default"id="entra">Entra</button>
</form>
This is my Servlet:

Model.BUtente.validate(mail,pw) returns true if the user (with e-mail=mail and password=pw) is a record of my DB, else returns false, I've tested it and works fine.

I did it!
If u have the same problem I'm posting here my solution:
My login form:
<form id="login" class="form-horizontal" action="LoginServlet" method="GET">
<div class="form-group">
<label class="control-label col-xs-8 col-sm-4 col-md-5" for="mail">E-mail:</label>
<div class="col-xs-10 col-sm-8 col-md-4">
<input type="text" class="form-control" id="mail" name="mail" placeholder="E-mail">
</div>
</div>
<div class="form-group">
<label class="control-label col-xs-8 col-sm-4 col-md-5" for="pw">Password:</label>
<div class="col-xs-10 col-sm-8 col-md-4">
<input type="password" class="form-control" id="pw" name="pw" placeholder="Password">
</div>
</div>
<br>
<button type="submit" class="btn btn-default"id="entra">Entra</button>
</form>
