Try something like this -
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "Host" AS
import java.io.*;
public class Host
     public static void executeCommand(String command)
     try {
            String[] finalCommand;
               if (isWindows())
                    finalCommand = new String[4];
                    // Use the appropriate path for your windows version.
                    finalCommand[0] = "C:\\windows\\system32\\cmd.exe"; // Windows XP/2003
                    //finalCommand[0] = "C:\\winnt\\system32\\cmd.exe"; // Windows NT/2000
                    finalCommand[1] = "/y";
                    finalCommand[2] = "/c";
                    finalCommand[3] = command;
               else
                    finalCommand = new String[3];
                    finalCommand[0] = "/bin/sh";
                    finalCommand[1] = "-c";
                    finalCommand[2] = command;
          final Process pr = Runtime.getRuntime().exec(finalCommand);
         pr.waitFor();
         new Thread(new Runnable()
            public void run()
                  BufferedReader br_in = null;
               try
                    br_in = new BufferedReader(new InputStreamReader(pr.getInputStream()));
                    String buff = null;
                    while ((buff = br_in.readLine()) != null)
                              System.out.println("Process out :" + buff);
                           try {Thread.sleep(100); } catch(Exception e) {}
                    br_in.close();
               catch (IOException ioe)
                    System.out.println("Exception caught printing process output.");
                    ioe.printStackTrace();
             finally
                 try {
                          br_in.close();
                      } catch (Exception ex) {}
     ).start();
     new Thread(new Runnable()
       public void run()
            BufferedReader br_err = null;
            try
               br_err = new BufferedReader(new InputStreamReader(pr.getErrorStream()));
               String buff = null;
               while ((buff = br_err.readLine()) != null)
                    System.out.println("Process err :" + buff);
                    try
                       Thread.sleep(100);
                     } catch(Exception e) {}
               br_err.close();
           catch (IOException ioe)
               System.out.println("Exception caught printing process error.");
               ioe.printStackTrace();
          finally
              try
                      br_err.close();
               catch (Exception ex) {}
      ).start();
     catch (Exception ex)
              System.out.println(ex.getLocalizedMessage());
  public static boolean isWindows()
          if (System.getProperty("os.name").toLowerCase().indexOf("windows") != -1)
          return true;
          else
          return false;
CREATE OR REPLACE PROCEDURE Host_Command (p_command IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'Host.executeCommand (java.lang.String)';
--- THE PERMISSIONS ---
call dbms_java.grant_permission('SYSTEM', 'SYS:java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
call dbms_java.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
call dbms_java.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');And, finally,
create or replace procedure call_sql_file(usr  in varchar2,
                                          pwd  in varchar2,
                                          host_str in varchar2)
is
begin
   host('sqlplus -s usr/pwd@host_str C:\UAX_Auto_Count.sql');
exception
  when others then
    dbms_output.put_line(sqlerrm);
end;Now, you can pass all the argument in order to execute that file.
N.B.: Not Tested...
