SLL: running my web services on your WS platforms

ABSTRACT

Today, the choice for a particular programming language limits the alternative products that can be used to deploy the program. For instance, a Java program must be executed using a Java VM. This limitation is particularly harmful for the emergence of a new programming paradigm like SOA and Web Services because platforms for new innovative programming languages are typically not as stable and mature as the established platforms for traditional programming paradigms. The purpose of this work is to break the strong ties between programming languages and runtime environments and thus make it possible to innovate at both ends independently. Thereby, the specific focus is on Web Services and Service-Oriented Architectures; focusing on this domain makes it possible to achieve this goal with affordable efforts. The key idea is to introduce a Service Language Layer (SLL) which gives a high-level abstraction of a service-oriented program and which can easily and efficiently be executed on alternative Web Services platforms.
