How to run a bash script in java-ee web application?

Question

I have a web application writen in jsp/servlets & tomcat 7.It will run on linux systems.

I want to run a bash script with root privilages( gksudo ./myScript.sh ). My script is under /web directory.( /web/myScript.sh ). How can i do that??

I have seen some examples, i managed to run bash shell command(like ls ), but didn't managed to execute the script!! How i can set as working directory the /web/ ?

Check out the following method to figure out how to get the path to your script:

• ServletContext.getRealPath()

To execute a script, you can use the Runtime class like this:

String[] commandArray = {
    "/bin/bash",
    "-c",
    "my_script.sh"
}

Runtime.getRuntime().exec(commandArray);

I've never tried running a script using sudo (or gksudo), so you'll have to play around with that.

Hopefully you can just add it to the array before the script name.
