<div class="wiki-content maincontent"><p>CMS (stands for C++ Messaging Service) is a JMS-like API for C++ for interfacing with Message Brokers such as <a shape="rect" class="external-link" href="http://activemq.apache.org">Apache ActiveMQ</a>. CMS helps to make your C++ client code much neater and easier to follow. To get a better feel for CMS try the <a shape="rect" href="api.xml">API</a> Reference. ActiveMQ-CPP is a client only library, a message broker such as <a shape="rect" class="external-link" href="http://activemq.apache.org">Apache ActiveMQ</a> is still needed for your clients to communicate.</p><p>Our implementation of CMS is called ActiveMQ-CPP, which has an architecture that allows for pluggable transports and wire formats. Currently we support the <a shape="rect" href="openwire-support.xml">OpenWire</a> and <a shape="rect" href="stomp-support.xml">Stomp</a> protocols, both over TCP and SSL, we also now support a Failover Transport for more reliable client operation. In addition to CMS, ActiveMQ-CPP also provides a robust set of classes that support platform independent constructs such as threading, I/O, sockets, etc. You may find many of these utilities very useful, such as a Java like Thread class or the "synchronized" macro that let's you use a Java-like synchronization on any object that implements the activemq::concurrent::Synchronizable interface.
