Sun ONE Message Queue is a product. It is a production implementation of the JMS
specification. Sun ONE Message Queue software performs the function of a message
broker, essentially serving as a common denominator enabling the exchange of
information between applications. A number of competing products perform this same
function, but Sun ONE Message Queue software adds the availability of JMS APIs to
promote an open, industry-standard interface to messaging middleware, thus
promoting the platform interoperability of Java while also enabling developers of
business applications to write to only a single interface. In and of itself, this does not
make Sun ONE Message Queue software unique since other MOM products also
conform to the JMS specification. However, the combination of JMS with high
performance, low cost, ease of use, and Sun's world class distribution and support
channels makes Sun ONE Message Queue software a highly competitive product.
