你是java的新手，所以面对一些问题，我从一个html页面调用servlet，它从不同的类调用不同的方法，但是从servlet执行类的方法时，它抛出的文件没有找到异常。但是一切存在于正确的道路上。虽然分别运行类的方法，但它的工作正常，但是从servlet开始它不是

my test.java

public class test {
    //String filenaame="WebContent/prop/html.txt";
    /*public static void main(String[] args) throws IOException{
        test t= new test();

        t.read(filenaame);
    }*/

    String line="";


    public List<String> read(String filename) throws IOException
    {
        File file =new File(filename);
        FileReader fi = new FileReader(file);
        BufferedReader in = new BufferedReader(fi);
        List<String> tokens = new ArrayList<String>();
        while((line=in.readLine())!=null){
            tokens.add(line);
            System.out.println("entering");

        }
        return tokens;
    }

我的servlet

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

response.setContentType("text/html");  
PrintWriter out = response.getWriter();  
String Filename="WebContent/prop/html.txt";
test t = new test();

List<String> line=t.read(Filename);
for (String s : line) {
    System.out.println(s);
out.print(s);}


}

通过servlet运行时找不到文件异常
