Provided are a computer program product, system, and method for distributing services to client systems to develop in a shared development environment. A first service is deployed to the first client system to develop the first service. A second service is deployed to the second client system to develop the second service. A call is received from the first service, executing in the first client system as part of development of the first service, to the second service. A determination is made as to whether the second service is deployed at the second client system and available in response to the call from the first service. A response is generated to the call to the second service from a component in the shared development environment in response to determining that the second service is deployed at the second client system and not available.

Distributing services to client systems to develop in a shared development environment

A JMS implementation integrates into an application server based on the JCA Architecture. A JMS Connection is integrated based on one implementation of a 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 ignores any security credentials provided. The application is unaware that it is 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 implementation and not directly from the application.

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.
