Java can't run a shell script [duplicate]

I face a problem to run a ".sh" file from my Java code, which is written in bash. At this point, I am using the following command to run the script (which is in the local directory, and seems to be found):

Process proc1 = Runtime.getRuntime().exec("./"+ nomScript);
proc1.waitFor();

But when executing, I get the error:

CreateProcess error=193, %1 n’est pas une application Win32 valide

(%1 is not a valid Win32 application, the whole error is in the code section below).

java.io.IOException: Cannot run program "./OAD_TCI_20_Blocage.sh": CreateProcess error=193, %1 n’est pas une application Win32 valide

I tried few things to run the script, as pointing the path to bash.exe as:

Process proc1 = Runtime.getRuntime().exec("pathTobash.exe -c "+ nomScript);

But nothing seems to work.

Does anyone know how I could run this script? Thank you
