我想创建一个servlet项目。
我的Java类名为AzpanaServlet.java
,其中包含一个内部类。(编译后会生成2个类文件)。
我的项目是一个简单的应用程序,接收一个字符串输入并对其进行一些操作(与主题无关)。
当我点击"提交"
按钮时,出现以下错误:
HTTP Status 404 - /AzpanaServlet
Type Status report
Message /AzpanaServlet
Description The requested resource (/AzpanaServlet) is not available.
Apache Tomcat/6.0.18
如果您能帮忙,我将不胜感激。我已经花费了很多时间也无法解决这个问题。 以下是我的Java代码:
public class AzpanaServlet extends HttpServlet {
//
//Some functions
//
//Inner class: public class oneChar{...}
//
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
/*
* Get the value of form parameter
*/
String name = request.getParameter("name");
/*
* Set the content type(MIME Type) of the response.
*/
response.setContentType("text/html");
String str = "";
PrintWriter out = response.getWriter();
ArrayList<Integer> list = new ArrayList<Integer>();
try {
list = mainmanu(name); //not relevant function.
} catch (Exception e) {
str = e.toString();
e.printStackTrace();
}
/*
* Write the HTML to the response
*/
out.println("<html>");
out.println("<head>");
out.println("<title> this is your answers</title>");
out.println("</head>");
out.println("<body>");
if(str != ""){
out.println(str);
}
else{
for(int i = 0;i<=40;i++){
out.println(list.get(i));
out.println("<br>");
}
}
out.println("<a href='form.html'>"+"Click here to go back to input page "+"</a>");
out.println("</body>");
out.println("</html>");
out.close();
}
public void destroy() {
}
}
我的web.xml
