T3
Weblogic developed protocol for efficiently transporting data between a Weblogic server and other Java programs (including other Weblogic servers).  Can multiplex multiple services over a single network connection.
Tuxedo Connector
API to connect to BEA Tuxedo transaction processing services.  Weblogic can invoke Tuxedo services and Tuxedo can invoke EJB applications.
.war File
Web Archive, created using Java jar utility.
