Question

i want to pass form parameters to a servlet for processing i.e. i have a username and password here is my form code. does the action clause have to append the username and password or does it do it automatically?
<form name="form1" method="post" action="<%= response.encodeURL("/bookstore/controller?action=login&username=username&password=password") %>">
      <p>Username:</p>
        <input type="text" name="username">
      <p>Password:</p>
        <p>
          <input type="text" name="password">
        </p>
        <p>
          <input type="submit" name="Submit" value="Submit">
        </p>
      </form>

Answer 1

The form does it automatically.
Your action only has to be "/bookstore/controller?action=login"
