Discover ActiveMQ brokers with Delphi XE4 and Indy 10.6

This article shows how Delphi can use IP multicast to discover running Apache ActiveMQ message brokers in the local network. The code has been tested with Internet Direct (Indy) 10.6, which is the version included in Delphi XE4, and Apache ActiveMQ 5.8, which is the current release of the open source message broker.

With the code below, a Delphi application can list all ActiveMQ brokers, see their status, and get their IP address. This allows for dynamic configuration of client applications (built for example with Habari Client for ActiveMQ), where systems do not need to know the location of message brokers. It also allows automatic handling of broker failures or maintenance windows without intervention.

Example output

The output shows that a broker was found, running on the computer ‘my-PC’. The URL part indicates that the broker provides a connector for the OpenWire protocol on port 61616.

Waiting for broker discovery messages ...
Brokers found:
default.ActiveMQ-4.alive.%localhost%tcp://my-PC:61616

RPC with Delphi client and Java server using RabbitMQ (part 1 of 2)

The RabbitMQ online tutorial Remote procedure call (RPC) – using the Java client demonstrates how RPC can be implemented between a Java client and a Java server process, communicating over the RabbitMQ open source message broker.

But access to the RPC server process is not limited to Java applications – Delphi and Free Pascal applications using the Habari Client for RabbitMQ library can invoke the server process method too.

This article shows the code for a Delphi client which sends a RPC call message to the inbound RabbitMQ request queue, and receives the response message over a temporary queue, which exists only for the duration of the connection.

Habari Client for Apollo 1.3 released

December 18, 2012 – Habarisoft is pleased to announce release 1.3 of Habari Client for Apollo. The new release is mainly a bug fix release.

Apollo is a messaging broker built from the foundations of the original ActiveMQ. It accomplishes this using a radically different threading and message dispatching architecture.
