我正在执行以下程序，通过Java调用shell，但是我遇到了异常，请帮助我。
程序：
import java.io.*;
import java.util.*;
public class ProcessExample {
/**
* @param args
*/
public static void main(String args[]) throws IOException {
File file=new File("/opt/nilesh/fazal");
ProcessBuilder processBuilder = new ProcessBuilder("./LicenseGen.sh --batchfile commands.txt");
processBuilder.directory(file);
processBuilder.redirectErrorStream(true);
System.out.println("nilesh");
Process process=processBuilder.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
System.out.printf("Output of running %s is:",
Arrays.toString(args));
while ((line = br.readLine()) != null) {
System.out.println(line);
}
OutputStream os=process.getOutputStream();
OutputStreamWriter osw=new OutputStreamWriter(os);
BufferedWriter bw=new BufferedWriter(osw);
bw.write("create licensekey -x license-input.xml");
while ((line = br.readLine()) != null) {
System.out.println(line);
}
}
}
和异常
