关于RunTime.getRunTime.exec() 在控制台程序里RunTime.getRunTime.exec("cmd.exe /c ...")能够执行脚本来控制远程,为什么在JSP里就不行了??大虾们,帮忙解释下啊 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 刚巧以前写过,调用本地的net send 命令import java.util.*;import java.io.*;class StreamGobbler extends Thread{ InputStream is; String type; StreamGobbler(InputStream is, String type) { this.is = is; this.type = type; } public void run() { try { InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line=null; while ( (line = br.readLine()) != null) System.out.println(type + ">" + line); } catch (IOException ioe) { ioe.printStackTrace(); } }}public class GoodWindowsExec{ public static void main(String args[]) { int times=100; if (args.length < 1) { System.out.println("USAGE: java GoodWindowsExec <cmd>"); System.exit(1); } try { for(int i=0;i<=times;i++){ String osName = System.getProperty("os.name" ); String[] cmd = new String[3]; if( osName.equals( "Windows 2000" ) ) { cmd[0] = "cmd.exe" ; cmd[1] = "/C" ; cmd[2] = args[0]; } else if( osName.equals( "Windows 95" ) ) { cmd[0] = "command.com" ; cmd[1] = "/C" ; cmd[2] = args[0]; } Runtime rt = Runtime.getRuntime(); System.out.println("Execing " + cmd[0] + " " + cmd[1] + " " + cmd[2]); Process proc = rt.exec(cmd); // any error message?
