2.4.2 Oracle WebLogic Server to Oracle Tuxedo Connectivity

EJB application servers in a WebLogic Server application can invoke services and CORBA objects in an Oracle Tuxedo application using the WTC and TDomain gateways. The following figure shows how this connectivity is implemented.

Figure 2-3 WebLogic Server to Tuxedo Connectivity Using WTC

The WTC and TDomain gateways allow WebLogic Server EJBs, JSPs, or Java servlets acting as clients to access Oracle Tuxedo services. The WTC gateway converts the EJB/JSP/servlet JATMI request to an ATMI request, and the TDomain gateway delivers the ATMI request to an Oracle Tuxedo ATMI server offering the requested service.

Similarly, the gateways allow WebLogic Server EJBs, JSPs, or Java servlets acting as clients to access Oracle Tuxedo CORBA objects. The WTC gateway inserts the EJB/JSP/servlet CORBA Java or RMI-over-IIOP request inside of an Oracle Tuxedo GIOP (TGIOP) request message, and the TDomain gateway delivers the TGIOP request to an Oracle Tuxedo CORBA server offering the requested object.
