从 Java 调用 Python

我想打电话给python来自 Java 的脚本。我的python版本是2.5，Java版本是6。

我当前的代码：

try{
    Process p= Runtime.getRuntime().exec("path/dirs/file.py");
    p.waitFor();
    } catch (InterruptedException ex){
    System.out.println(ex.getMessage());}
    }

我收到的错误是：

Java.IO.IOException：无法运行程序文件名：CreateProcess 错误 = 193, %1 不是有效的 Win32 应用程序

尝试使用PrecessBuilder -

try{

   String prg = "import sys\nprint int(sys.argv[1])+int(sys.argv[2])\n";
   BufferedWriter out = new BufferedWriter(new FileWriter("test1.py"));
   out.write(prg);
   out.close();
   int number1 = 10;
   int number2 = 32;

   ProcessBuilder pb = new ProcessBuilder("python","test1.py",""+number1,""+number2);
   Process p = pb.start();

   BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
   int ret = new Integer(in.readLine()).intValue();
   System.out.println("value is : "+ret);
}catch(Exception e){System.out.println(e);}
