When Java is running and you use Runtime.exec() with a relative path, relative means relative to the current user direcory, where the JVM was invoked.

This may work

Runtime.getRuntime().exec("cmd.exe", "/c", "./com/projct/util/server.bat");

if you start java from com's parent directory.

Or you must calculate an absolut path:

Runtime.getRuntime().exec("cmd.exe", "/c", 
System.getProperty("user.dir")+"/com/projct/util/server.bat");

I forget, read When Runtime.exec() won't.
