Increase fault tolerance in business processes utilizing platform capabilities

Services are certainly assuming an increasingly important role in modern application development, composite application. One may ask how to successfully introduce Service Oriented Architecture (SOA), which is the foundation for composite applications. The objective of this study is to examine the key issue of users´ negative attitude towards introduction of SOA architecture. According to experience so far, it is the fear of complexity that the SOA brings with its layers. Composite applications must be reliable and available, in the same manner traditional applications are. However, it may appear more difficult to achieve, due to the multi-layered architecture of the SOA. To reduce the fear of complexity, as well as to reduce the risk when introducing SOA architecture, it is necessary to use effective error handling method in order to increase system fault tolerance. The aim of this paper is to present an error handling framework by means of the platform properties that are used for building the SOA architecture.
