Answer 1

<jsp:include page="/product/newproductinfo.jsp" />这一句你试试是不是你用回车分成二行了.另外
org.apache.jasper.JasperException: Exception in JSP: /product/newproductinfo.jsp:74 <%=lt.get(i).getUserIp().substring(0, lt.get(i).getUserIp().lastIndexOf(",")) 你看看你所取数组的下标是不是越界了.

Answer 2

String index out of range: -1 
越界了

Answer 3

谢谢各位的支持！我解决了。是SUBSTING的问题

Answer 4

呵呵.
肯定是SUBSTING截取时出了问题.
