Cuando se aplica la actualización de 10.1.3.1 a 10.1.3.4 ó bien de 10.1.3.3 a 10.1.3.4 es común encontrarse con el siguiente error al querer entrar al BPELConsole:

Para resolverlo hay que realizar lo siguiente:

1. Todo consiste en remplazar el ejb_ob_engine.jar con una copia que se encuentra en otra carpeta. Lo siguiente asume que la SOA Suite (BPEL) está ejecutándose en el container OC4J_SOA.
2. Primero hay que parar el container con: opmnctl stopproc process-type=OC4J_SOA
3. Cambiarse a la carpeta $ORACLE_HOME/j2ee/OC4J_SOA/applications/orabpel
4. Borrar el archivo: ejb_ob_engine.jar
5. Copiar el archivo $ORACLE_HOME/bpel/system/j2ee/ejb/ejb_ob_engine_oc4j.jar a la carpeta $ORACLE_HOME/j2ee/OC4J_SOA/applications/orabpel
6. Renombrarlo de ejb_ob_engine_oc4j.jar a ejb_ob_engine.jar
7. Iniciar la SOA SUITE: opmnctl startproc process-type=OC4J_SOA

Con esto al entrar al BPELConsole ya no se tendrá el problema anteriormente mencionado.
