InvList.jsp的代码如下：
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<%@ taglib uri="/WEB-INF/struts-nested.tld" prefix="nested" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ page contentType="text/html; charset=GBK" %>
<%@ page contentType="text/html; charset=GBK" %>
<html:html>
<head>

错误如下：
XXX bad jar classes12.zip
"InvList.jsp": java.lang.NullPointerException
"InvList.jsp": error:org.apache.jasper.JasperException: Error compiling \InvList.jsp
"InvList.jsp": java.lang.NullPointerException老是提示第一句
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
有错，这是怎么回事啊？？？？？
