I need to get error from sql script launched from class

Question

Hello.
I need to run a bat file (windows xp) inside a PL/SQL procedure and I must check the codes returned by the command.
I am trying with these files:
comando.bat
sqlplus -s fernando/sayaka@ferbd %1
exit /Bkk.sql
whenever sqlerror exit sql.sqlcode rollback
declare
  v_res number;
begin
  select 1
       into v_res
       from dual
   where 1=2;
end;
exit sql.sqlcodeEjecutarProcesoSOreturn.java
import java.lang.Runtime; 
import java.lang.Process; 
import java.io.IOException; 
import java.lang.InterruptedException;   
public class EjecutarProcesoSOreturn
    public static int ejecuta(java.lang.String  arg0, java.lang.String arg1)
        java.lang.String[] args= new String[2];
        args[0]=arg0;
        args[1]=arg1;
        int ret = 0;
        System.out.println("En ejecuta");           
        try
            /* Se ejecta el comando utilizando el objeto Runtime
            y Process */               
            Process p = Runtime.getRuntime().exec(args);      
            try
                /* Esperamos la finalizacion del proceso */                 
                ret = p.waitFor(); 
                //ret = p.exitValue();                
            catch (InterruptedException intexc)
                System.out.println("Se ha interrumpido el waitFor: " +  intexc.getMessage());
                ret = -1;            
            System.out.println("Codigo de retorno: "+ ret);    
        catch (IOException e)
           System.out.println("IO Exception de exec : " +               e.getMessage());              
           e.printStackTrace();          
           ret = -1;            
        finally
           return ret;
    public static void main(java.lang.String[] args)
        System.out.println("En main");  
        System.out.println("args[0] " + args[0]);           
        System.out.println("args[1] " + args[1]);   
        ejecuta(args[0], args[1]);
}  When I launch the script from a console I get:
D:\Ejercicios_Oracle\BATCH_SCRIPTS>comando.bat @kk.sql
D:\Ejercicios_Oracle\BATCH_SCRIPTS>sqlplus -s fernando/sayaka@ferbd @kk.sql
declare
ERROR en lÝnea 1:
ORA-01403: no se han encontrado datos
ORA-06512: en lÝnea 4
D:\Ejercicios_Oracle\BATCH_SCRIPTS>exit /BAnd if I check the errorlevel I get:
D:\Ejercicios_Oracle\BATCH_SCRIPTS>echo %errorlevel%
1403When I run it the class I get:
D:\Ejercicios_Oracle\BATCH_SCRIPTS>java EjecutarProcesoSOreturn comando.bat @kk.sql
En main
args[0] comando.bat
args[1] @kk.sql
En ejecuta
Codigo de retorno: 0And if I check the errorlevel I get:
D:\Ejercicios_Oracle\BATCH_SCRIPTS>echo %errorlevel%
0How can I get the code 1403 returned from the class?
Thanks in advance.

I am trying to extract the error code from the Process.getInputStream() but it seems as if I do not have some privileges.
This is my class right now:
import java.lang.Runtime; 
import java.lang.Process; 
import java.io.IOException; 
import java.lang.InterruptedException;   
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.InputStream;
public class EjecutarProcesoSOreturn
    public static int ejecuta(java.lang.String  arg0, java.lang.String arg1)
        java.lang.String[] args= new String[2];
        args[0]=arg0;
        args[1]=arg1;
int ret = -100;
        //System.out.println("En ejecuta");           
        try
            /* Se ejecuta el comando utilizando el objeto Runtime y Process */     
            Process p = Runtime.getRuntime().exec(args);      
ret = -101;   
            try
                /* Esperamos la finalizacion del proceso */                 
                ret = p.waitFor(); 
                //ret = p.exitValue();
                InputStream bis = p.getInputStream();
                InputStreamReader isr = new InputStreamReader(bis);
                BufferedReader br = new BufferedReader(isr);
                String line = null;
                String msg = null;
                String errCode = null;
                boolean oraError = false;
ret = -102;   
                while ( (line = br.readLine()) != null)   
                  //System.out.println(line);
                  if ((line.length() >= 5) & (!oraError))
                    msg = line.substring(0,4); 
                    if (msg.equals("ORA-"))
                         oraError = true;
                         errCode = line.substring(4,9);
ret = -103;   
                      //System.out.println(errCode);
                      ret = Integer.parseInt(errCode);;
            catch (InterruptedException intexc)
                //System.out.println("Se ha interrumpido el waitFor: " +  intexc.getMessage());
                ret = -1;            
        catch (IOException e)
           //System.out.println("IO Exception de exec : " +               e.getMessage());              
           //e.printStackTrace();          
           ret = -1;            
        catch (Exception e)
           //System.out.println("IO Exception de exec : " +               e.getMessage());              
           //e.printStackTrace();          
           ret = -104;            
        finally
           //ret = -100;   
           System.out.println("Codigo de retorno: "+ ret);
           return ret;
    public static void main(java.lang.String[] args)
        System.out.println("En main");  
        System.out.println("args[0] " + args[0]);           
        System.out.println("args[1] " + args[1]);   
        ejecuta(args[0], args[1]);
}  And when I call the main method with these parameters then I get:
D:\Ejercicios_Oracle\BATCH_SCRIPTS>java EjecutarProcesoSOreturn d:\comando.bat @d:\kk.sql
En main
args[0] d:\comando.bat
args[1] @d:\kk.sql
Codigo de retorno: 1403I have this pl/sql function:
CREATE OR REPLACE FUNCTION FERNANDO.EjecutarProcesoSOreturn (param1 VARCHAR2, param2 VARCHAR2) return NUMBER
AS LANGUAGE JAVA  name 'EjecutarProcesoSOreturn.ejecuta(java.lang.String, java.lang.String) return java.lang.int';I have granted some privileges to the user FERNANDO:
begin
    dbms_java.grant_permission
    ('FERNANDO',
     'java.io.FilePermission',
     'd:\comando.bat',
     'execute');
    dbms_java.grant_permission
    ('FERNANDO',
     'java.lang.RuntimePermission',
     'writeFileDescriptor' );
    dbms_java.grant_permission
    ('FERNANDO',
     'java.lang.RuntimePermission',
     'readFileDescriptor' );
    dbms_java.grant_permission
    ('FERNANDO',                   
     'java.io.FilePermission',    
     'd:\*',               
     'read,write');
end;
/and when I try the function, I get:
SQL> DECLARE
  2    RetVal NUMBER := 0;
  3    PARAM1 VARCHAR2(200);
  4    PARAM2 VARCHAR2(200);
  5 
  6  BEGIN
  7    PARAM1 := 'd:\comando.bat';
  8    PARAM2 := '@d:\kk.sql';
  9 
10    RetVal := EJECUTARPROCESOSORETURN ( PARAM1, PARAM2 );
11    dbms_output.put_line('RetVal: '||RetVal);
12    --ROLLBACK;
13  END;
14  /
RetVal: -102Could you please tell me what my problem is?
