Abstract: An entitled price in an electronic transaction is provided to a public electronic environment (e.g., a browser on a global computer network) from a private electronic environment (e.g., an ERP application on a private computer network) by electronically sending from a requestor a request for an entitled price via a public electronic environment; automatically routing the request to a private electronic environment; obtaining the entitled price within the private electronic environment while the requestor waits; and automatically returning the entitled price from the private electronic environment to the public electronic environment for providing to the requestor.

Abstract: Synchronous communications between a public electronic environment (e.g., a browser on a global computer network) and a private electronic environment (e.g., an ERP application on a private computer network) are facilitated by automatically routing a communication from the browser to the ERP application through messaging middleware, obtaining by the messaging middleware a reply from the ERP application in response to the communication while the browser and messaging middleware wait therefor, and automatically returning the reply from the ERP application to the browser. Encryption and firewalls are also used for security.
