JMS API history
IBM, among others, was involved actively with Sun Microsystems in the specification process that led to the original JMS API being published in 1999. Several versions of the API have subsequently been released. The latest is V1.1, which includes many changes that resulted from a review of the API by the Java community.
It is important to note that the JMS API defines a vendor-independent programming interface. It does not define how the messaging provider should be implemented or which communication protocol should be used by clients to communicate with the messaging provider. Different vendors can produce different JMS implementations. They should all be able to run the same JMS applications, but the implementations from different vendors will not necessarily be able to communicate directly with each other.
