You can use ProcessBuilder for this. It provides much more control than exec. Particularly, it allows to set working directory with method directory.

Example:

ProcessBuilder pb = new ProcessBuilder("server.bat");
pb.directory(new File(deployDir + "\\com\\project\\util"));
Process p = pb.start();
int exitStatus = p.waitFor();

Of course, your app must get deployDir from somewhere. It can be set in environment, in application configuration file, it can be current user directory or anything else.
