The <jsp:forward> action enables you to forward the request to a static HTML file, a servlet, or another JSP. <jsp:forward page="url" /> The JSP that contains the <jsp:forward> action stops processing, clears its buffer, and forwards the request to the target resource. Note that the calling JSP should not write anything to the response prior to the <jsp:forward> action. You can also pass additional parameters to the target resource using the <jsp:param> tag. <jsp:forward page="test.htm" > <jsp:param name="name1" value="value1" /> <jsp:param name="name2" value="value2" /> </jsp:forward>
