System and method for supporting a proxy model for across-domain messaging in a transactional middleware machine environment

A system for supporting messaging in a transactional middleware machine environment, comprising:

• one or more microprocessors;
• a first transaction domain, running on the one or more microprocessors, wherein the first transaction domain operates to export one or more services to a second transaction domain, wherein said one or more services are imported from a third transaction domain;
• and
• a first gateway server in the transaction domain that operates to
• receive a request from a client in the second transaction domain to invoke said one or more services in the third transaction domain;
• and
• route the request to a server in the third transaction domain that provides said one or more services.

A non-transitory machine readable storage medium having instructions stored thereon that when executed cause a system to perform the steps comprising:

• exporting, via a first transaction domain, one or more services to a second transaction domain, wherein said one or more services are imported from a third transaction domain;
• receiving, via a first gateway server in the transaction domain, a request from a client in the second transaction domain to invoke said one or more services in the third transaction domain;
• and
• routing, via the first gateway server, the request to a server in the third transaction domain that provides said one or more services.
