java - Execute bash script in eclipse -

i'm trying figure out how execute simple bash script java program inside eclipse. have checked questions cannot run program "..../abc.exe": error=13, permission denied , permission denied when running shell script java program, still have error:

ioexception: cannot run program "prog" error=13, permission denied.

i have checked file permissions:

-rwxrwxr-x user user prog

i use snippet execute script:

file file = new file(this.getclass().getclassloader().getresource("prog").getfile()); processbuilder processbuilder = new processbuilder(file.getabsolutepath()); try {   process process = processbuilder.start();   process.waitfor(); } catch (ioexception e) {   // todo auto-generated catch block   e.printstacktrace(); } catch (interruptedexception e) {   // todo auto-generated catch block   e.printstacktrace(); } 

when invoking bash scripts java must specify '/bin/bash' executable , pass script path argument.
