This page takes 3 values that you specify, and forwards them to another JSP.
That JSP will create a URL to another page, that then extracts the
parameters and displays them.
<p />
<form action="createURL.jsp" method="post">
<table>
<tr><td>Enter name:</td>
<td><input type="text" name="name" /></td></tr>
<tr><td>Enter age:</td>
<td><input type="text" name="age" /></td></tr>
<tr><td>Enter gender:</td >
<td><input type="text" name="gender" /></td></tr>
</table>
<input type="submit" value="Submit details" />
</form>
