Herald is an easy-to-use messaging framework. It allows Pelix/iPOPO and Java OSGi frameworks to communicate with each other using messages, without worrying about the underlying protocol used for transmission.
The project is hosted on GitHub isandlaTech/cohorte-herald. Issues and questions can be posted in project Issues section.
Concepts
Each Pelix framework instance is considered as a peer. A peer has a unique ID and a human-readable name. An application ID is associated to each peer: only peers with the same application ID can discover each other.
A peer can send a message to another peer or to a group of peers. A message has a subject, which listeners register to, and a content.
Remote Services
Herald provides an RPC transport implementations for Pelix Remote Services.
Transports
Currently, Herald supports two protocols in Python, and one in Java:
HTTP (Python & Java):
Each message is sent as a POST request.
Peer discovery is based on a home-made multicast heart beat protocol
Best transport for LAN applications and for single-peer messages
Implementation is based on requests.
XMPP (Python only, for now):
Each message is a either a message or a group message
Discovery is based on a Multi-User Chat room (XEP-0045)
Best transport for distributed applications and for group messages
Implementation is based on SleekXMPP
