Answer 1

首先确认一下路径是否存在 /cpt/TestConnection/WebRoot/WEB-INF/classes/
然后确认java程序的用户是否有权限
/bin/sh的执行权限，和/cpt/TestConnection/WebRoot/WEB-INF/classes/路径的访问权限

Answer 2

路径存在 但是java程序的用户的权限怎么弄的。。还望指点下

Answer 3

chmod 755 *

Answer 4

public void tar_compress(String dirPath, String fileNames, String fileName) {
String cdCmd = "cd " + dirPath.trim();

String cutCmd = "tar czvf /cpt/TestConnection/upload/"
+ fileName.trim() + ".tar.gz ";
cutCmd += fileNames;
String[] cmd = new String[]{"/bin/sh","-c","ls",cdCmd,"ls",cutCmd}; //System.out.println(cdCmd);
System.out.println(cutCmd);
//String[] arr = {cdCmd, cdCmd1, cdCmd2, cdCmd3, cdCmd4, cutCmd };
CmdExec(cmd); // return ;
} public void CmdExec(String[] cmdline) {
 String line;
Process p = null;
try {
if (p != null) {
p.destroy();
p = null;
}
p = Runtime.getRuntime().exec(cmdline);
//p.wait(10000);
 BufferedReader input = new BufferedReader(new InputStreamReader(p
 .getInputStream()));

 line = input.readLine();
 int i=0;
 while (true) {
i++;
 if(i>50){
 break;
 }
 //while (line != null) {
 line = input.readLine();
 System.out.println(line);
 }

p.waitFor();
input.close();
int ret = p.exitValue();
//System.out.println("ret=:"+ret);
} catch (Exception err) {
err.printStackTrace();
} finally {
if (p != null) {
close(p.getOutputStream());
close(p.getInputStream());
close(p.getErrorStream());
p.destroy();
}
}
}
这是代码 java有执行权限的 打把出来是一个空包
