标题[JSP ] 请教有关Runtime.exec错误的问题
时间Mon Mar 2 13:24:23 2009
我想写一个网页 然後放在windows架的apache上
藉这个jsp网页去执行cluster程式 然後产生一些资料
再用网页去抓那些资料回来
目前我的想法是
写一个1.bat档内容是
@echo off
putty.exe -ssh xxx.xxx.xxx.xxx -l ptt -pw "ptt" -m linuxcmd.cmd
linuxcmd.cmd内容是
sync
cd mix1/
./testBash.sh
testBash.sh内容是
#!/bin/bash
/cluster/opt/mpich2/bin/mpdboot -n 8 -f mpd2.hosts
/cluster/opt/mpich2/bin/mpiexec -n 8 ./ok_MPI_GME_PBF.o
连结到cluster linux上去下指令
下一些执行的语法 等执行完会产生一些资料
再用网页抓资料回来
但是目前把bat放到apache上
网页的内容是
<%@ page contentType="text/html; charset=big5"
pageEncoding="Big5" language="java" import="java.sql.*,
java.util.Date, java.io.* , java.lang.Runtime.*" errorPage="" %>
<html><head><title>Insert title here</title></head><body>
<%
Runtime o_run_notepad = Runtime.getRuntime();
o_run_notepad.exec("1.bat");
%>
</body></html>
开启网页後会跳一个错误讯息
java.io.IOException: Cannot run program "1.bat": CreateProcess error=2
我在猜这个讯息是不是说我不能在远端的windows上建立process去执行?
如果我在我自己电脑上直接执行1.bat确定可以完整产生档案
但是把这几个档案放在网路远端 然後用网页去呼叫执行就会错
请问我该怎麽修改才可以让使用者利用网页就可以跑这个程式
不用把那些档案下载到自己端再执行
麻烦会的大大帮我解答一下 真的很感谢
***************************************************************
第一次try自己电脑上执行bat
目前我是先试在自己电脑上执行1.bat档
已确定可以连到cluster下指令执行平行程式
也确定有跑完 产生档案
第二次try利用网页执行本机端bat
再试验利用网页的方式去执行本机端的1.bat
当档案在自己电脑上时 确定可以正常跑完所有的指令
第三次try利用网页执行远端的bat档(绝对路径)
但是把那些档案放在server端时
再用网页方式去执行就会跳
