Envio de Correos con ATTACH desde Base Datos Oracle

Paso 1: Configuración

Descargar JavaMail y los  Javabeans Activation Framework:

	JavaMailTM API Implementation Version 1.2
	JavaBeans Activation Framework 1.0.1 release

En Windows

loadjava.bat -user sys/password -resolve -synonym activation.jar
loadjava.bat -user sys/password -resolve -synonym mail.jar

En Unix

loadjava -user sys/password -resolve -synonym activation.jar
loadjava -user sys/password -resolve -synonym mail.jar

Desde SQLPLUS

sqlplus /nolog
connect sys/manager as sysdba;

SQL> call sys.dbms_java.loadjava('-v -r -grant PUBLIC -synonym jaf-1.0.1\activation.jar');
 SQL> call sys.dbms_java.loadjava('-v -r -grant PUBLIC -synonym javamail-1.2\mail.jar');

Configuración

Una vez que las clases han sido cargadas en el servidor de base de datos es requerido dar permisos  sobre la ruta en donde se registrarán los attach.

sqlplus /nolog
connect sys/manager as sysdba;

SQL> exec dbms_java.grant_permission('SCOTT','java.util.PropertyPermission','*','read,write');
 SQL> exec dbms_java.grant_permission('SCOTT','java.net.SocketPermission','*','connect, resolve');
 SQL> exec dbms_java.grant_permission('SCOTT','java.io.FilePermission','C:\Users\Prueba\Attach\*','read, write');
