As middleware is dependent on the network protocol being used, the
effectiveness of the underlying transport protocol must be considered.
Implementing MOM
Using the Java Message Service
The Java Message Service (JMS) developed by Sun
Microsystems, Inc. is part of the Java2 Enterprise Edition (J2EE) platform. JMS
is an Application Programming Interface (API) for accessing MOM systems in Java
Programs. JMS, however, is not only operable within the Java domain, but it can
also be integrated with other middleware technologies, such as CORBA and
Microsoft.NET.
JMS provides a set of interfaces and good abstraction that defines
how wireless middleware can be implemented. For this reason, JMS has become
widely accepted in the industry as the API to follow.
The JMS API is not specifically intended for the wireless
domain. Traditional JMS was designed to allow Java applications to communicate
with existing wire-line MOM systems. As a result, a full JMS implementation is
too "fat" for wireless devices, because low power consumption and a smaller
memory footprint are required (Spiritsoft, 2002). However, JMS has become the "de facto"
standard as an API for wireless middleware.
