Abstract
A service call to a backend system is initiated by a user interface in a service-oriented architecture. Thereafter, a service answer is received from the backend system encapsulating a backend error object. The backend error object is mapped to a front end error object. A front end error message can later be presented to a user in the user interface that is derived from the front end error object. Related apparatus, systems, techniques and articles are also described.
Claims20
An article comprising a non-transitory machine-readable storage medium embodying instructions that when performed by one or more machines result in operations comprising:
- initiating a service call to a backend system by a user interface in a service-oriented architecture;
- receiving a service answer from the backend system encapsulating a backend error object;
- mapping the backend error object to a front end error object;
- and
- presenting a front end error message derived from the front end error object in the user interface;
- wherein the backend error object contains variables that are each described by a type and a corresponding business semantic, the variables being used to generate the front end error object.
A computer-implemented method comprising:
- initiating a service call to a backend system by a user interface in a service-oriented architecture;
- receiving a service answer from the backend system encapsulating a backend error object;
- mapping the backend error object to a front end error object;
- and
- presenting, in the user interface, a front end error message derived from variables in the front end error object;
- wherein the backend error object contains variables that are each described by a type and a corresponding business semantic, the variables being used to generate the front end error object.
A system comprising:
- a front end system comprising a user interface;
- and
- a backend system coupled to the front end system via TCP/IP in a service-oriented architecture;
- the front end system initiating a service call to the backend system via the user interface;
- the backend system generating a service answer to the service call that includes a backend error object;
- the front end system mapping the backend error object to a front end error object so that a front end error message derived from the front end error object can be presented in the user interface, the front end error message being different than a backend error message included in the backend error object;
- wherein the backend error object consists of:
- an ID field for an identification for a corresponding message;
- a short text field that includes a first number of characters to describe the corresponding message;
- a long text field that includes a second number of characters to describe the corresponding message, the second number being greater than the first number;
- a severity field that characterizes a severity of the corresponding message;
- a preview field that includes a preview of the message;
- a variables table containing variables that includes an identification of each variable, a type of each variable, a length of each variable, and a description of each variable.
