JMS integration into an application server

Thus the present invention provides a method which enables a JMS implementation to be integrated into an application server based on the JCA Architecture. In this method the JMS Connection is integrated based on one implementation of the JCA which sets transactional context for the JMS Connection to no transaction, and the JMS Session is integrated based on a second implementation of the JCA which sets the security property to no security. In the method the application is unaware that is it dealing with a JCA implementation and not directly with the JMS implementation and the JMS implementation is unaware that it is being called via the JCA and not directly from the application. The method thus provides an architecture for integration of a JMS into an application server which takes advantage of the JCA such as provision of security properties and transactional context to the JMS in a standard way, and JMS connection pooling and sharing.
