Multi-tier application architecture
First Claim
1. A multi-tier application architecture having a middletier comprising:
- a framework to mediate between an application and a middletier, wherein the framework allows a middletier to execute an object fetched by an application from a cache;
wherein, when an object becomes stale, the framework repeatedly refreshes the object within a limited number of retries;
wherein, when an object refresh succeeds, the framework returns the object to the cache and again allows the middletier to execute the object; and
wherein, when an object refresh does not succeed within a limited number of retries, the framework quits an application in fail-safe way.

Abstract
The present invention aims at providing a multi-tier application architecture that fast accesses objects and has a fail-safe function against middletier crash. A framework mediates between an application and a middletier and allows the middletier to execute an object fetched by the application from a cache. When an object becomes stale, the framework repeatedly refreshes that object within a limited number of retries. When the refresh succeeds, the framework returns the object to the cache and again allows the middletier to execute the object. When the refresh does not succeed within the specified number of retries, the framework quits the application in a fail-safe state.
