What is STOMP...

STOMP - The Streaming (or Simple) Text Oriented Messaging Protocol
So, what is STOMP? Simply put, its a Text Oriented protocol for messaging between two applications or through a message broker. 
Officially it goes, STOMP provides an inter-operable wire format so that STOMP clients can communicate with any STOMP message broker to provide easy and widespread messaging interoperability among many languages, platforms and brokers.
STOMP is text-based and does not use binary protocols. It supports a range of core enterprise messaging features, such as authentication, messaging models like P2P & publish and subscribe, message acknowledgement, transactions, message headers & properties, etc.,
There are number of messaging protocols like AMQP, MQTT, etc., but STOMP stands out as one of the popular messaging protocols which is Text based. 
All leading Messaging brokers support STOMP protocol, for STOMP compliant message brokers refer here.
A nice comparison between leading messaging prot…

WSO2 - Registry setup

Image
All WSO2 products are shipped with a built-in registry, supported by the H2 Database packaged with the product. Though its sufficient for many applications, its not recommended for Enterprise integration applications and Production environments.

In our case the ESB registry is mounted with WSO2 Governance Registry (GREG). The below steps can be used to change the ATOM based registry mount (default) with JDBC based mount.

The following example was implemented on the systems which had deployed resources and services, servicing other applications.

GREG 1. In GREG, replace WSO2_CARBON_DB in master-datasources.xml with JDBC details.

<datasource>
   <name>WSO2_CARBON_DB</name>
   <description>The datasource used for registry and user manager</description>
