Answer 1

尝试添加-jar ：

p.command("java.exe", "-jar", "C:\\Users\\zareeba\\Desktop\\KictCHE_UAT");

Answer 2

尝试通过添加-jar作为参数来尝试执行此操作

p.command("java.exe", "-jar", "C:\\Users\\zareeba\\Desktop\\KictCHE_UAT.jar");

Answer 3

You are missing the -jar flag. You need to add the -jar flag like this:

p.command("java.exe", "-jar", "C:\\Users\\zareeba\\Desktop\\KictCHE_UAT");

Answer 4

You can use below code to run exe file:

 try {
     ProcessBuilder pb = new ProcessBuilder("cmd", "/C", "C:\\Users\\user\\Desktop\\Test.jar");
     Process process = pb.start();    
    } catch (Exception e) {
        System.out.println("e="+e);
    }
