jsp中用request传递,在action中却接受不到
我在RateList.jsp中有这样一段代码<html:form act=eproducerateComeIn><%String eff_year=(String)request.getAttribute("eff_year");System.out.println("eff_year页面:::::::"+eff_year);有结果,假设2request.setAttribute("eff_year", eff_year);%><td width=35% align=left><html:text property="SHORTNAME" /><input type="submit" value="查 询"></html:form><SCRIPT LANGUAGE="JavaScript">mygrid.loadXML("<%=request.getContextPath()%>/eproducerate.do?act=query");</SCRIPT>但是在action中 if(actionFlag.equals("query")){ String eff_year=(String)request.getAttribute("eff_year"); eff_year却为null,这是怎么回事 }领导说了,不能用session,否则系统会崩溃,因为系统会崩溃(这点很重要) 我之前用的session被要求改过来
