如何在jsp网页间传送一个值（例如：即时时间），此值为已赋值的变量，让它在另一个网页里显示！

最好是通过 变量名 在 jsp网页间传送，有 submit 表单！不知道是否可行！知道的大侠希望不吝赐教！

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.HttpURLConnection;
import java.net.URL;

public class T {
public static String GetPageContent(String _url) {
BufferedReader br = null;
InputStreamReader isr = null;
InputStream is = null;
PrintWriter pw = null;
HttpURLConnection huc = null;
String pageContent = "";
try {
URL url = new URL(_url);
huc = (HttpURLConnection) url.openConnection();
is = huc.getInputStream();
isr = new InputStreamReader(is);
br = new BufferedReader(isr);
String line = null;
while (((line = br.readLine()) != null)) {
if (line.length() == 0)
continue;
pageContent += line;
}
} catch (Exception e) {
System.err.println(e);
} finally {
try {
is.close();
isr.close();
br.close();
huc.disconnect();
pw.close();
} catch (Exception e) {
}
}
return pageContent;
}

}

然后调用这个方法就可以，参数就是url

例如传入参数""
另外,虚机团上产品团购,超级便宜

我。。知。。道 加。。我。。私。。聊
