• sending the message, from the sending application, according to the protocol;
• and
• receiving, at the receiving application, the message;
• wherein the class of messages includes one of:
• an application-message class associated with application messages that cause specified operations to be performed at the receiving application, an application-response class associated with messages responsive to the application messages of the application-message class, an application-error class associated with error messages indicative of errors occurring at the receiving application processing the application messages and a system-acknowledge class associated with acknowledgement messages indicative that one or more application messages have been received by the receiving application.

A method of transporting a message from a sending application to a receiving application, across a messaging landscape in a collaborative network, the method comprising:

• receiving an application message, from the sending application, at a first component of the collaborative network, the application message having a structured application message header, the structured message header being defined in accordance with a protocol of a business application of a collaborative business enterprise and in accordance with a message class determinative of content and configuration of the message header, the structured application message header comprising one or more components defined by the protocol and based on the message class with each of the one or more components relating to an associated set of attributes of the message;
• in response to the first component successfully receiving the message, the first component sending a transport level acknowledgement to the sending application;
• the first component modifying the message to include the first component on a hop-list in the message;
• the first component causing the message to be sent to the receiving application;
• in response to receiving an acknowledgement message, from a second component, indicating that the message has been received by the receiving application, the first component sending a transport level acknowledgement to the second component;
• wherein the message class having one of multiple possible values including:
• a first value representative of an application-message class associated with application messages that cause specified operations to be performed at the receiving application, a second value representative of an application-response class associated with messages responsive to the application messages of the application-message class, a third value representative of an application-error class associated with error messages indicative of errors occurring at the receiving application processing the application messages and a fourth value representative of system-acknowledge class associated with acknowledgement messages indicative that one or more application messages have been received by the receiving application.

A system to transport a message from a sending application to a receiving application, across a messaging landscape in a collaborative network, the system comprising:

• at least one processor connected to the network;
• and
• at least one storage device coupled to the at least one processor, the at least one storage device storing computer instructions that, when executed on the at least one processor, cause the at least one processor to:
• define an application message having a structured application message header, the structured message header being defined in accordance with a message class of the application message determinative of content and configuration of the message header and in accordance with a messaging protocol of a business application of a collaborative business enterprise, the structured application message header comprising one or more components defined by the protocol and based on the message class with each of the one or more components relating to a corresponding set of attributes of the message, at least one of the one or more components including version information, the version information indicating the protocol used to define the message;
• send the message according to the protocol;
• and
• receive, at a messaging component in the messaging landscape, the message, the messaging component being operative to process the message based on the version information included in the message;
• wherein the message class having one of multiple possible values including:
