请教关于javax.servlet.RequestDispatcher.forward(request, response)

摘要: 请教关于javax.servlet.RequestDispatcher.forward(request, response)

我在request中有一个参数this.request.setAttribute("APercentValue", this.strAPERCENT);
strAPERCENT="1.11"; 执行到javax.servlet.RequestDispatcher.forward(request, response);这句的时候就会出错 错误内容是org.apache.jasper.JasperException: For input string: "1.11"

但是如果是整数就没有问题,请教是为什么呢?

把代码贴上来看看

---

看看你的代码中是否有 string Number 或者 字符串format

---

private String strAPERCENT = "1.11";
protected void doPost(HttpServletRequest _request, HttpServletResponse _response) throws ServletException, IOException {
try {
this.request.setAttribute("APercentValue", this.strAPERCENT);
RequestDispatcher myRequestDispatcher = null;
myRequestDispatcher = getServletContext().getRequestDispatcher("/JSP/AGENT/" + strPageName);
myRequestDispatcher.forward(request, response);
}

基本是这样的 到了FORWARD就会出错

---

代码中没有转类型的 从数据库取出来之后就一直以String 型进行操作的

---

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

String strAPERCENT = "1.11";

request.setAttribute("APercentValue", strAPERCENT);
RequestDispatcher myRequestDispatcher = null;
myRequestDispatcher = getServletContext().getRequestDispatcher(
"/index.html");
myRequestDispatcher.forward(request, response);

上面的代码在我的机器上能够正常执行。把错误栈堆贴上来看看。

找到原因了 不是FORWARD的问题 谢谢啦~~
