run a .sh file using java

I want to run a .sh file using java. I want a terminal to be opened and then I can execute another commands in the same terminal and finally destroy it. I already used ProcessBuilder but I could not accomplish this. My piece of code:

ProcessBuilder pb = new ProcessBuilder("/home/omar/ros_ws/baxter2.sh");
Process p = pb.start();

This method used to work in another code, but I don't know why it's not working in mine.

Thanks in advance

How do you know that it doesn't execute? Maybe you just aren't seeing its result. You should get p.getInputStream() after executing and print in your console, like:

BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = null;
while ((line = reader.readLine()) != null)
{
   System.out.println(line);
}

Also if you're using jdk 7+, try:

pb.redirectOutput(Redirect.INHERIT);
pb.redirectError(Redirect.INHERIT);
Process p = pb.start();

I think you should grant the .sh file the executable permission to the OS user used to run the java program by using the below command.

chmod u+x baxter2.sh

Does your program output an error, or is your program not interacting with the file?

I would suggest trying the directory method within ProcessBuilder.

Process p = null;
ProcessBuilder pb = new ProcessBuilder("baxter2.sh");
pb.directory("/home/omar/ros_ws");
p = pb.start();

If this doesn't work, you should also look into user permissions for the file that you're trying to access.
