Automated Input through openSSL command prompt

Question

I am trying to automate the process of creating a CSR through openSSL and command prompt while using a Java program. I want to input a string such as koo_AH, Kut_Po and uuu_Pl and turn them into CSRs with default parameters. I was able to create the key file, but not the CSR, which I believe has to do with the fact that openSSL will start asking for parameters. What am I doing wrong here? Below is code as well as input/output of command prompt while manually using it in a nonjava process.

while (true) {
        input[i] = inputScan.next();
        if (input[i].length() < 5) {System.out.println("End of creation"); break;}
        common = ("aaa."+ input[i].substring(4)+".aaa.com").toLowerCase();
        pass = "aaa"+input[i].substring(4)+year;

        rt = Runtime.getRuntime();
        pr = rt.exec("cmd.exe");
        pr = rt.exec("cmd /c cd "+directory1+" && " //change directory
                + "set OPENSSL_CONF=c:\\OpenSSL-Win32\\bin\\openssl.cfg && " //setup
                + "openssl genrsa -out "+directory2+input[i]+".key 2048 &&" //generate key
                + "openssl req -new -key "+directory2+input[i]+".key -out "+directory2+input[i]+".key.csr &&"
                + countryName + " &&"
                + state + " &&"
                + locality + " &&"
                + organization + " &&"
                + unit + " &&"
                + common + " &&"
                + email + " &&"
                + pass + " &&"
                + company);



        i++;
    }
