java jsp:forward标签使用，jspforward,jsp的forward标

jsp的forward标签用来做页面的跳转：

<jsp:forward page="otherpage">    <jsp:param name="age" value="37"/>    <jsp:param name="weight" value="206"/></jsp:forward>

上面的标签和下面的代码是等价的：

/* clear the buffer before forward. if write into unbuffer out, and then forward, exception occur if write more than the size of buffer, and then forward, exception occur*/out.clear():pageContext.forward("otherpage"+"?age=37&weight=206");
