Using XMLink Universal Gateway

XMLink Universal Gateway adds another product to the XMLink family:

• XMLink—enables J2EE-compliant servers, such as IBM WebSphere, to call Oracle Tuxedo services.

• XMLink Universal Gateway—enables Oracle Tuxedo applications to call services deployed in enterprise applications on other Enterprise Information Systems (EISs).

With XMLink Universal Gateway, your Oracle Tuxedo applications can access services deployed in other enterprise applications the same way that you access Tuxedo services. No change is needed in how services are called in your Tuxedo applications. This lets you maintain your existing Tuxedo systems and still gain access to services deployed on other enterprise application servers.
