WebLogic Tuxedo Connector Overview

The WebLogic Tuxedo Connector provides interoperability between WebLogic Server applications and Tuxedo services. The connector allows WebLogic Server clients to invoke Tuxedo services and Tuxedo clients to invoke WebLogic Server Enterprise Java Beans (EJBs) in response to a service request.

Key Functionality and Administrative Features

The WebLogic Tuxedo Connector enables you to develop and support applications interoperating WebLogic Server and Tuxedo by using a Java Application-to-Transaction Monitor Interface (JATMI) similar to the Tuxedo ATMI. The WebLogic Tuxedo Connector tBridge functionality provides Tuxedo /Q and JMS advanced messaging services.

The WebLogic Tuxedo Connector provides the following bi-directional interoperability:

• Ability to call WebLogic Server applications from Tuxedo applications and vice versa or to call EJBs.

• Ability to integrate WebLogic Server applications into existing Tuxedo environments.

• Transaction support.

• Ability to provide interoperability between CORBA Java and CORBA C++ server applications.

• Ability to use WebLogic Process Integrator to manage workflow across Tuxedo ATMI services, including eLink 1.2 adapters.

• Ability to define multiple connections between WebLogic Server and Tuxedo.

The WebLogic Tuxedo Connector includes the following key administration features:

• Simple implementation. The WebLogic Tuxedo Connector does not require modification of existing Tuxedo application code.

  • Existing Tuxedo clients call WebLogic Server EJBs through the WebLogic Tuxedo Connector.

  • New or modified WebLogic Server clients call Tuxedo services through WebLogic Tuxedo Connector.

• Bi-directional security propagation, including domain and ACL security.

• Domain-level failover and fallback.

• Advanced messaging services provided by Tuxedo /Q and JMS.

• Interoperability with mainframes and other legacy applications using eLink.

Known Limitations

WebLogic Tuxedo Connector has the following limitations:

• Does not support dynamic configuration changes to the WebLogic Tuxedo Connector gateway.

• Does not support inbound RMI/IIOP or outbound CORBA in clustered environments.

• Does not support Tuxedo 6.5 running on VMS and OS/390 platforms.

• Does not support outbound CORBA applications from WebLogic Server running on IBM AIX platforms. WebLogic Server uses a Sun specific extension for creating sockets that is not compatible with IBM JDK.

How WebLogic Tuxedo Connector Differs from Jolt

The WebLogic Tuxedo Connector is not a replacement for Jolt. WebLogic Tuxedo Connector differs from Jolt in the following ways:

• WebLogic Tuxedo Connector offers a similar but different API than Jolt.

• Jolt enables the development of generic Java clients and other Web server applications that the WebLogic Tuxedo Connector does not.

• Jolt does not provide a mechanism for an integrated WebLogic Server-Tuxedo transaction.

Users should use Jolt as a solution instead of the WebLogic Tuxedo Connector when a generic Java client or other Web server application is required and WebLogic Server is not part of the solution.

Documentation

You can download the WebLogic Tuxedo Connector documentation from the following location:

• On the BEA corporate Web Site. From the BEA Home page at http://www.bea.com, click on Product Documentation.

• Go directly to the WebLogic Server "e-docs" product documentation page at http://e-docs.bea.com/index.html. Follow the links from the WebLogic Server 7.0 Documentation Center.

Platform Support

See our Platforms Support page for the most accurate and current information regarding platform support.

Licensing

Note: For more information on WebLogic Server licensing information, see Installing a WebLogic Server License.

This section provides licensing information for the WebLogic Tuxedo Connector:

• There is no license requirement for using the connector without encryption.

• An appropriate Tuxedo LLE license and an appropriate WebLogic Server SSL license is required to use encryption.

Updating WebLogic Tuxedo Connector 6.x Applications

You must make some changes in your WebLogic Tuxedo Connector 6.x applications (including WebLogic Tuxedo Connector 1.0) to use them with WebLogic Server 7.0. For detailed information on the administration and programming changes required to upgrade to WebLogic Tuxedo Connector in WebLogic Server 7.0, see Upgrading WebLogic Server 6.x to Version 7.0.
