读文件时得权限问题

Question

以下是我在applet中调用的Hello类，webServerStr路径是由文件中读的，
运行时系统抛出例外，说没有读webserver.prop的权限，该怎么办啊？import java.util.*;
import java.io.*;
import java.net.*;
import java.util.Properties;public class Hello {  public static Properties settings = getServerInfo();
  public static String hostName = settings.getProperty("HOSTNAME");
  public static String port = settings.getProperty("PORT");
  public static String servletPath = settings.getProperty("SERVLETPATH");  private static String webServerStr = "http://" + hostName + ":" + port + servletPath;  /**
   * get the MonModel object
   */  public static Properties getServerInfo(){
    Properties defaultSettings=new Properties();
    defaultSettings.put("HOSTNAME","192.168.100.219");
    defaultSettings.put("PORT","9080");
    defaultSettings.put("SERVLETPATH","/Monitor/MonServlet");        Properties settings=new Properties(defaultSettings);
        try{
          FilePermission perm = new FilePermission (".\\*", "read");
          FileInputStream sf=new FileInputStream("webserver.prop");
          settings.load(sf);        }catch(FileNotFoundException e){ System.out.println("Properties File webserver not found!"); }
        catch(IOException e) { System.out.println("IOException is found!"); }
        return settings;
  }}
