2.4.1 Oracle Tuxedo to Oracle WebLogic Server Connectivity

Oracle Tuxedo application clients and servers can invoke EJB objects in a WebLogic Server application, which in turn can invoke other EJB objects, JSPs, or Java servlets. The following figure shows how this connectivity is implemented.

Figure 2-2 Tuxedo to WebLogic Server Connectivity

Note:

Oracle Tuxedo clients include ATMI clients, Jolt clients, and CORBA C++ clients. For a high-level view of Tuxedo clients, see “Client and Server Components” in Oracle Tuxedo Product Overview.

The TDomain gateway not only enables Tuxedo domains to share services with other Oracle Tuxedo domains, but it enables Tuxedo domains to share services with WebLogic Server 6.1or later installations through the WTC gateway. The WTC gateway supports the TDomain gateway protocol.

The gateways allow Tuxedo ATMI clients, and Tuxedo ATMI servers acting as clients, to access WebLogic Server EJB objects. The TDomain gateway delivers the ATMI client request to the WTC gateway, and the WTC gateway converts the request to an RMI call to access the appropriate EJB object.

Similarly, the gateways allow Oracle Tuxedo CORBA clients, and Tuxedo CORBA servers acting as clients, to access WebLogic Server EJB objects. The TDomain gateway delivers the CORBA RMI-over-IIOP client request to the WTC gateway, and the WTC gateway forwards the request to the appropriate EJB object.
