在机房内，我们相邻的两台电脑。。我下载往另一台机器上东西，谁知道怎么实现啊？？
也就是我想在网页中实现文件下载。。。从客户端下载服务器上的东西
客户端连接
<a href="MyDownloadAction.action">点击下载</a>
Action
import java.io.InputStream;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class MyDownloadAction extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;
public InputStream getDownloadFile(){
InputStream is=ServletActionContext.getServletContext().getResourceAsStream("http://10.3.5.32:8080/ROOT/1.txt");
System.out.println(is);
return is;
}
@Override
public String execute() throws Exception {
return SUCCESS;
}
}
上面的方法下载本机能实现
可是下载另一台机器上的资源就实现不了了
高手帮我看看把、、、、
