Ubuntu中使用Runtime.getRuntime().exec时出现Permission denied

[banjiamayi]

在Ubuntu中运行如下代码时出错：
String path = "/home/GMT/";
Process process;
process = Runtime.getRuntime().exec ("chmod 777 " + path + "map.sh");
process = Runtime.getRuntime().exec (path + " ./map.sh");

错误：

权限问题.

[lxxzhy]

process = Runtime.getRuntime().exec ("chmod 777 " + path + "map.sh");
process.waitFor();
process = Runtime.getRuntime().exec (path + " ./map.sh");

说一下怎么解决的啊.

[捏造的信仰]

/home/GMT/ 只是一个目录，而不是一个命令。

楼主运行的是chmod

[banjiamayi]

使用process.waitFor(); 后问题依然存在！

String path = "/home/GMT/";
Process process;
process = Runtime.getRuntime().exec("chmod 777 " + path + "map.sh");
process.waitFor();
process = Runtime.getRuntime().exec("/bin/sh "+path+"map.sh");
用了"/bin/sh"就可以了！
