The Service Level Agreements (SLA) are e-Contracts that need to be established among business partners and monitored to ensure that web services comply with the agreed Quality of Service (QoS) values. Existing approaches deal with automated contract generation for simple Web Services. Many business enterprises implement their core business service, while outsourcing other application services. When a single service cannot satisfy the user requirements, multiple Web Services must be composed which can together fulfill the request. Therefore, establishment of SLA among the component services of a composite service and the users becomes important. Hence, we have designed and implemented a framework for generating and monitoring e-Contracts for business applications involving composite Web Services. We have demonstrated our work using the scenarios of an Insurance application. A template based approach is used for composing the Web Services dynamically.
