Services are certainly assuming an increasingly important role in modern application development, composite application. One may ask how to successfully implement Service-Oriented Architecture (SOA).The objective of the study to examine the key issue of the user's negative attitude towards introduction of SOA design. It is the fear of complexity that the SOA brings with its layers .Composite applications must be reliable and available, however it may appear more difficult to achieved, due to the multi-layered architecture of SOA. To reduce the fear of complexity, as well as to reduce the risk when introducing SOA architecture, it is necessary to use error handling methods in order to increase system fault tolerance. This paper looks at various error handling considerations associated with design of reusable services. It provides an outlineof what error handling considerationsapply during SOA analysis and design phases. Also describes some best practices into designing these considerations. Finally ensuring that services are designed and implemented in all its completeness.
