How to define form action in JSF?

The best solution for me is to use the default <button> tag instead. Since typical button styling is not being applied (in my case I am using Primefaces), I set it manually. Here’s the whole result:

    <h:outputStylesheet library="primefaces" name="jquery/ui/jquery-ui.css" />
    <h:outputStylesheet library="css" name="login.css" />

    <div class="message">
        <c:if test="#{param.error == 1 and SPRING_SECURITY_LAST_EXCEPTION != null}">
            <span class="error">#{SPRING_SECURITY_LAST_EXCEPTION.message}</span>
        </c:if>
    </div>



    <div class="login">
        <form action="../j_spring_security_check" method="post">
            <h:panelGrid columns="2">
                <h:outputText value="Username" />
                <h:inputText id="j_username" />
                <h:outputText value="Password" />
                <h:inputSecret id="j_password" />
            </h:panelGrid>

            <div class="submit">
                <button type="submit" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only">
                    <span class="ui-button-text">Login</span>
                </button>
            </div>
        </form>
    </div>
