在进行MVC+DAO实现分页的时候碰到了这个异常：
严重: Servlet.service() for servlet PersonServlet threw exception

出现错误部分代码是
<jsp:include page="person_com.jsp">
<jsp:param name="jspUrl" value="<%=jspUrl %>"/>
<jsp:param name="lineSize" value="<%=request.getAttribute("lineSize") %>"/>
<jsp:param name="currentPage" value="<%=request.getAttribute("currentPage") %>"/>
<jsp:param name="allRecoders" value="<%=request.getAttribute("allRecoders") %>"/>
<jsp:param name="keyWord" value="<%=request.getAttribute("keyWord") %>"/>
<jsp:param name="searchFlag" value="T"/>
</jsp:include>
搜索了下，在csdn中的
http://blog.csdn.net/qzj5851/archive/2009/08/12/4437493.aspx
中发现了相同的问题。按照他的解决方法修改如下：
<jsp:include page="person_com.jsp">
<jsp:param name="jspUrl" value="<%=jspUrl %>"/>
<jsp:param name="lineSize" value='<%=request.getAttribute("lineSize") %>'/>
<jsp:param name="currentPage" value='<%=request.getAttribute("currentPage") %>'/>
<jsp:param name="allRecoders" value='<%=request.getAttribute("allRecoders") %>'/>
<jsp:param name="keyWord" value='<%=request.getAttribute("keyWord") %>'/>
<jsp:param name="searchFlag" value="T"/>
</jsp:include>
就是把value=""改成value=''。
问题是解决了，但是看他里面说是tomcat6.0版本的问题，可是我使用的是tomcat5.5的版本也出现这个问题。
我这个项目是使用到了servlet的，我还有一个是使用JSP+DAO实现分页的项目。在那个项目里面同样的代码就没有出现过这个问题。
自己现在猜测是tomcat解析servlet时候出现的一个问题。留待有时间的时候再来解决。
