Your can use:
Process p = Runtime.getRuntime().exec("your command");
first. Then get IOStream from this process to read/write info. |

发帖数: 3 | 2 I wanna test if there is a duplicate instance running.
So, I am trying to call the following unix commands,
ps acx > ./ps_Client.txt
and
grep -c Client ./ps_Client.txt > ./grep_Client.txt
but when I try to open the file grep_Client.txt, I got the
FileNotFoundException, there is no such file at all.
The follows are my code,
String SysCommand = "ps acx > ./ps_Client.txt";
Process p = Runtime.getRuntime().exec(SysCommand);
SysCommand = "grep -c Client ./ps_Client.txt > ./grep_Client.txt";

发帖数: 31 | 3 is there any way that I can run a servlet from command line (like run CGI from
console)?
i am new for java.

发帖数: 31 | 4 thanks!
so there is no way to run from command line, right? |

发帖数: 67 | 5 The answer is Yes and No.
You can use mock object to simulate servlet environment and potentially
run/test your servlet without servlet container. However, that's more about
unit testing and it is an advanced topic.
Since you said you are new for Java, I do not want to confuse you here. So,
the answer is No. You can not run servlet from command line (without servlet
container). hehe

发帖数: 199 | 6 想起几年以前的糗事：
几年前servlet技术刚出来的时候我就开始用了，但还不会在线调试。
写好code编译后在服务器上跑，靠写log文件进行debug，那叫一个累啊。
后来发现可以在JBuilder里run一个Java Web Server,
通过配置让servlet在Java Web Server里运行，(相当于自己配了一个container)
这样就实现了在IDE环境里调试，那叫一个爽啊。
真后悔没早点引进这个“先进技术”。
而且那时还没有log4j，code里无数的 log语句，简直惨不忍睹。
现在回想起来不堪回首啊。
依赖别的实现，要运行需要container提供环境。启动container当然可以通过command

我考虑的方案是用一个local web server来实现widget 和这个程序的通信. WIDGET

个程序的EVENT怎样发送给WIDGET?
请高手支招!

发帖数: 7227 | 31 Hi, someone mentioned this last time,
the latest ubuntu is using network-manager to set static/dhcp.
So i cannot use command line to change this anymore ?
BTW,
in /etc/network/interfaces,
i only see
auto lo
iface lo inet loopback
nothing configured for eth0.
But when i boot up, it's using dhcp ?
Where does it get the configuration now ? |
