Retirement of WebLogic Tuxedo Connector 1.0

WebLogic Tuxedo Connector 1.0 is retired as of April 30, 2003. Although WebLogic Tuxedo Connector is no longer a standalone product, BEA has continued to develop WebLogic Tuxedo Connector as a service within WebLogic Server. WebLogic Server releases 6.1 and higher provide WebLogic Tuxedo Connector services with many feature enhancements. For more information see:

WebLogic Tuxedo Connector Overview

The WebLogic Tuxedo Connector provides interoperability between WebLogic Server applications and Tuxedo services. The connector uses a collection of jar and XML files that allow 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 Release 1.0 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
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.
Administered through an XML configuration file.
Out-bound transaction support (transactions originating in WebLogic Server).
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.

Limitations

This release of the WebLogic Tuxedo Connector has the following limitations:

Does not support dynamic configuration changes to the WebLogic Tuxedo Connector gateway
Does not support in-bound transactions (a transaction originating in Tuxedo)
Does not support Conversations
Does not support Views
Does not support double-byte character sets or international character sets. These features are dependent on future releases of Tuxedo.

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.

WebLogic Tuxedo Connector Distribution Files

The WebLogic Tuxedo Connector distribution contains the following files:

The WebLogic Tuxedo Connector jar file named jatmi.jar
A doc directory containing the JATMI Javadoc
A wtc_config.dtd data type definition file
Sample applications: simpapp, qsample, and simpserv
