程序是这样的：
list.jsp里显示的是信息某个内容的列表，想要做的是，点击“detail”这个单词，就会跳转到该信息的全部具体内容。
问题1：需不需要建立一个servlet.java？
如果不需要，能否显示出我点击的某个信息,而非所有~~因为在list.jsp里，每个列表都有id
问题2：如果需要建立一个servlet.java,如何将我点击的list的id传递给servlet,再传给detail.jsp。
list.jsp代码是这样的：
<%String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
Rentalproperty[] resultrp=(Rentalproperty[])session.getAttribute("sessionresultrp");
%>
