Abstract
This paper presents the architecture and implementation of the EOS2 failure-masking framework for composite Web Services. EOS2 is based on the recently proposed notion of interaction contracts (IC), and provides exactly-once execution semantics for general, arbitrarily distributed Web Services in the presence of message losses and component crashes without requiring explicit coding effort by the application programmer. The EOS2 implementation masks failures by adding a recovery layer to popular Web technology products: (i) the server-side script language PHP run on Apache Web server, and (ii) Internet browsers like IE to deliver recovery guarantees to the end-user.
