Developing Oracle WebLogic Tuxedo Connector Client EJBs
The following sections describe how to create client EJBs that take user input and send service requests to a server process or outbound object that offers a requested service.
■
Section 2.1, Joining and Leaving Applications
■
Section 2.2, Basic Client Operation
■
Section 2.3, Example Client EJB Oracle WebLogic Tuxedo Connector JATMI client classes are used to create clients that
access services found in Oracle Tuxedo.
2.1 Joining and Leaving Applications
Oracle Tuxedo and Oracle WebLogic Tuxedo Connector have different approaches to connect to services.
2.1.1 Joining an Application
The following section compares how Oracle Tuxedo and Oracle WebLogic Tuxedo Connector join an application:
■
Oracle Tuxedo uses tpinit to join an application.
■
Oracle WebLogic Tuxedo Connector uses a WTCServer MBean to provide information required to create a path to the Oracle Tuxedo service. Security and
client authentication is provided by configuring the Remote TDM and Imported Services MBean components of a WTCServer MBean. This pathway is created
when the Oracle WebLogic Server is started and a WTCServer MBean is present in the config.xml file and assigned targeted to a server.
■
Oracle WebLogic Tuxedo Connector uses TuxedoConnectionFactory to get a TuxedoConnection object and then uses getTuxedoConnection to make a
connection to the Oracle Tuxedo object. The following example shows how a Oracle WebLogic Server application joins an Oracle Tuxedo application using
Oracle WebLogic Tuxedo Connector.
Note: For more information on the Oracle WebLogic Tuxedo
Connector JATMI, view the Javadocs for WebLogic Classes. The Oracle WebLogic Tuxedo Connector classes are located in the
weblogic.wtc.jatmi and weblogic.wtc.gwt packages.
