Abstract: To solve the problem of the construction of fault tolerant scrviccoricnted software architecture, the paper proposed SOADL-EH, a new service-oriented software architecture description language (ADL) supporting exception handling. With the capability of modeling normal SOA and the provision of exception handling services(EHService)，exception handling connectors(EHConnector) and exception handling configurations(EHConfigure)，etc. software archilecture elements, this language can separate clearly the exception handling logic from the normal business logic of the service-oriented software architecture layer, which covers the shortage in exception handling capability of the existing ADLs.

Key words: SOA, ADL, Exception handling
