Calling .bat file from pl/sql

Question

I'm running Oracle 11g R2 on win7 system, and I would like to execute .bat file from a pl/sql block.
I created a .bat file
I have granted privs to an account:
BEGIN
  SYS.DBMS_JAVA.GRANT_PERMISSION(grantee => 'COMMON', permission_type   => 'SYS:java.io.FilePermission', permission_name   => '<<ALL FILES>>', permission_action => 'execute',key => KEYNUM);
END;
DECLARE
KEYNUM NUMBER;
BEGIN
  SYS.DBMS_JAVA.GRANT_PERMISSION(grantee => 'COMMON',permission_type   => 'SYS:java.lang.RuntimePermission',permission_name   => 'writeFileDescriptor',permission_action => '*',key => KEYNUM);
END;
DECLARE
KEYNUM NUMBER;
BEGIN
  SYS.DBMS_JAVA.GRANT_PERMISSION(grantee => 'COMMON',permission_type   => 'SYS:java.lang.RuntimePermission',permission_name   => 'readFileDescriptor',permission_action => '*' ,key => KEYNUM);
END;
DECLARE
KEYNUM NUMBER;
BEGIN
  SYS.DBMS_JAVA.GRANT_PERMISSION(grantee => 'COMMON',permission_type   => 'SYS:java.io.FilePermission',permission_name   => 'C:\dokumentacija\rman_backup\*',permission_action => 'read,write',key => KEYNUM);
END;
DECLARE
KEYNUM NUMBER;
BEGIN
  SYS.DBMS_JAVA.GRANT_PERMISSION(grantee => 'COMMON',permission_type   => 'SYS:java.io.FilePermission',permission_name   => 'C:\dokumentacija\rman_backup\*', permission_action => 'read',key => KEYNUM);
END;
DECLARE
KEYNUM NUMBER;
BEGIN
  SYS.DBMS_JAVA.GRANT_PERMISSION(grantee => 'COMMON', permission_type   => 'SYS:java.io.FilePermission', permission_name   => 'C:\windows\system32\*',permission_action => 'read',key   => KEYNUM);
END;
DECLARE
KEYNUM NUMBER;
BEGIN
  SYS.DBMS_JAVA.GRANT_PERMISSION(grantee=> 'COMMON',permission_type   => 'SYS:java.io.FilePermission',permission_name   => 'C:\windows\system32\*',permission_action => 'execute',key => KEYNUM);
END;
/this is Java:
CREATE OR REPLACE PROCEDURE runoscommand(cmd IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'Command.run(java.lang.String)';and this is how I call it:
declare
xx pls_integer;
v_errm varchar2(400);
begin
xx:=0;
xx:=archiver.fullBackup;
dbms_output.put_line(xx);
exception
    when others then
    v_errm:=substr(sqlerrm,1,400);
    dbms_output.put_line(v_errm);
end;this is Java code:
DROP JAVA SOURCE COMMON.COMMAND;
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED COMMON.COMMAND as import java.io.*;
import java.util.*;
public class Command{
public static void run(String cmdText)
                     throws IOException, InterruptedException
  int rtn;
       Runtime rt = Runtime.getRuntime();
  Process prcs = rt.exec(cmdText);
  rtn =  prcs.waitFor();
}I run this as a part of a package...
function fullBackup return pls_integer as
v_errm varchar2(200);
begin
    runoscommand('C:\dokumentacija\rman_backup\bckp_level_0.bat');
    return 0;
exception
    when others then
        v_errm:=substr(sqlerrm, 1,200);
        dbms_output.put_line(v_errm);
        return -1;
end fullBackup;but..
at the end, nothing happens..
what I've been missing?

I changed my code in last xx minutes...OK, so you've removed all your exception handlers?
so, now I'm calling to an exe file wich should appear at a desktop or processes list... but no..
I gave all windows rights on that file, and also through dbms_java.grant_permission..
but, nothing happened... not exception raised, no app. started...And no output from any DBMS_OUTPUT statement? Have you tried stepping through the code in your debugger?
