Abstract: Abstract The handling of violations of Service Level Agreement (SLA) is important for trustful service, particularly for web services in business field. In this paper, a SLA specification combines syntactic constructs from WS-Agreement and WSLA is proposed. Violations of SLA are prevented, detected and compensated by ECA (Event-Condition-Action) rules and constraint imperative programming (CIP) techniques. ECA constructor, inspired by the concept of constraint constructor used for handling user-defined constraints in CIP languages, is introduced for building and refactoring of ECA rules.
