我有几个JSP：home和graph。
我使用ajax：ExcelServlet从主JSP调用servlet。
我需要从servlet转发到图JSP。
我能够控制Servlet，所以映射和ajax调用都没问题。
然而，这种情况并没有发生。
$.ajax({
type: "get",
url: "CopyServlet",
beforeSend:function(){
$('#text3').css({"color":"red"});
$('#text3').text("Running Dynamic Diff Graph");
},
success:function(responseText){
$('#text3').css({"color":"green"});
$('#text3').text(responseText);
},
complete:function(){
$.ajax({
type: "post",
url: "ExcelServlet",
beforeSend:function(){
$('#text4').css({"color":"red"});
$('#text4').text("Preparing Difference Summary");
},
success:function(data){}
});
}
});
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ExcelExtract excelextract = new ExcelExtract();
excelextract.extract();
String newDup=excelextract.getNewDup();
request.setAttribute("newDup", newDup);
String diff=excelextract.getDiff();
request.setAttribute("diff", diff);
String newRecNA=excelextract.getNewRecNA();
request.setAttribute("newRecNA", newRecNA);
String oldRecNA=excelextract.getOldRecNA();
request.setAttribute("oldRecNA", oldRecNA);
String unchangedRec=excelextract.getUnchangedRec();
request.setAttribute("unchangedRec", unchangedRec);
if (diff.equals("0.0")){
request.setAttribute("message", "Test Passed: 0 differences");
}
else{
request.setAttribute("message", "Test Failed: Differences found");
}
request.getRequestDispatcher("graph.jsp").forward(request, response);
}
