在javabean中读取文件,代码如下:
String filename="\\sys.ini";
java.io.BufferedReader m = new java.io.BufferedReader(new

InputStreamReader(new FileInputStream(filename)));
int i=0;
while((c=m.readLine())!=null){
  argss[i]=c;
      out.print(argss[i]);
i++;
}  
把javabean发布到j2ee自带的deploytool上,以后无论怎么改

sys.ini的内容,程序读出的永远是第一次读sys.ini时的内容,这是

怎么回事。难道在服务器上有缓存

你的sys.ini存盘没有?

不应该有缓存的。你的那个sys.ini,是放在哪里的?。确认你改动的sys.ini是正确的。

The bean may or may not cached, depending on how the container implements it. The basic idea is not to do I/O wihtin a bean.

It's a javabean,,not an EJB,,,i suppose.
or I misunderstood it..sorry.

What do you mean by not doing it within a bean, where can i do it then?
