Hermes is a lightweight messaging service for applications based on J2SE/J2EE technologies. It allows to send and receive messages between various components of the application. Messages are persisted where needed in the RDBMS to ensure delivery after breakdowns. Although it is similar to JMS and provides similar API, it lacks its complexity. Hermes can be easily used in J2SE applications, as it does not relay on the J2EE application server.
