如何使用JSF 1.2将参数传递到包含的页面

<jsp:param>

例如

<jsp:include page="/WEB-INF/include.jsp">    <jsp:param name="position" value="top" /></jsp:include>...<jsp:include page="/WEB-INF/include.jsp">    <jsp:param name="position" value="bottom" /></jsp:include>

在上面的示例中，可以

${param.position}

<c:if test="${param.position == 'top'}">    This is a top include.</c:if><c:if test="${param.position == 'bottom'}">    This is a bottom include.</c:if>
