Jeg ved godt du har brugt meget tid på denne tråd nu, men jeg poster lige min koder som der er indtil videre. Det er ikke for at du skal kigge alt igennem, men springer dig noget i hovedet som er helt forkert?
JSP:
<td>
<form method="POST" action="CustomerController">
<input type="text" name="username" size="6">
</form>
</td>
<td class="formtext">Kode</td>
<td>
<form>
<input type="text" name="password" size="6">
</form>
</td>
