从java / Child Shell执行mount命令无法访问已安装的目录

Question

I have a python script that needs to be executed from java code . I use the below command :

 ScriptResult result = executor.executeCommand(Script,
            params.getParams(), false);

But executor.executeCommand() forks a new shell . I had run a mount command earlier and the contents of /mnt/folder1 are accessible from parent shell but not accessible from the newly forked child shell .

I have tried to execute the mount command , just before the executor.executeCommand() step using the following :

     String cmd = new String("/bin/mount ip:/folder1 /mnt/folder1");
     Process p = new ProcessBuilder(cmd).start();

and also

    String cmd = new String("mount"); String[] arg = new
    String[]{" ip:/folder1 ,"/mnt/folder1"}; Process pr =
 Runtime.getRuntime().exec(cmd); 

Both these give the following error :

    java.io.IOException: Cannot run program "mount ip:/folder1 /mnt/folder1":
    error=2, No such file or directory                      
   at java.lang.ProcessBuilder.start(ProcessBuilder.java:1041)                      
   at Caused by: java.io.IOException: error=2, No such file or directory

I have made a myscript.sh and copied the mount command and the python script command into the myscript . I invoked the myscript throgh java code and it was successful . But I should invoke the mount command from java code and not through a seperate script . Is there any way that I missed out. Thanks in advance .

try changing

 String cmd = new String("/bin/mount ip:/folder1 /mnt/folder1");

 Process p = new ProcessBuilder(cmd).start();

to

String[] cmd = new String[]{"/bin/mount", "ip:/folder1", "/mnt/folder1"};

Process p = new ProcessBuilder(cmd).start();
