Abstract:
1. A computer-implemented method for indicating a change in a service offering; the computer-implemented method comprising: generating a token representative of a state of the service offering including an application and resource, wherein the service offering is between a service provider and a service requester, wherein the token comprising a signature of a compiled code of the application, a signature of the resource used by the application and a timestamp of a last start up of the application, wherein the signature of the compiled code is generated using the timestamp combined with file size of the compiled code, and the signature of the resource is generated using a resource adapter code combined with a timestamp of a time the resource was last modified; determining whether the service offering has been modified to form a modified service, by monitoring the application and the resource for modifications; responsive to a determination that the service offering has been modified, generating a token representative of the state of the modified service; determining whether the service offering has been restarted to form a restarted service, by monitoring the application for a time of the last start up of the application; responsive to a determination that the offered service has been restarted generating a token representative of the state of the restarted service; and providing the token as a provided token to the service requester, wherein the service requester compares the provided token with a previously provided token to determine whether a change in the service offering exists.
