How to direct another page in JSP?

    <jsp:setProperty name="firstBean" property="sifre" /><br/>


    <c:choose>
        <c:when test="${firstBean.sifreKntrl()}">
    Hosgeldin!
    </c:when>
    <c:otherwise>
    <meta http-equiv="refresh" content="3;firma.html">

    </c:otherwise>
    </c:choose>

When I use if else condition by <% %> and it works but I couldn't direct to another page on else condition. Because of directive problem I used EL but now I couldn't make the code worked. That makes works both of the conditions.
