jsp中通过URL地址获取该地址页面中的静态页面
try {
URL url = new URL("http://www.163.com");
InputStream is = url.openStream();
byte[] buffer = new byte[1024];
int i;
while((i = is.read(buffer)) != -1){
System.out.println(new String(buffer,0,i));
}
} catch (Exception e) {
e.printStackTrace();
}

scope属性用于指定JavaBean实例对象所存储的域范围，其取值只能是page、request、session和application四个值中的一个，其默认值是page。
我可以测试下面代码：
date.jsp
---------------------------------------------------------
<jsp:useBean i ......
public class TaskBean extends Thread{
public TaskBean(){
}
private int percent=0;
private boolean complete=false;
