Here we will breifly describe the object-oriented architecture of the JAWS Web server framework. In order to understand the design, it is important to motivate the need for framework architectures.
Solutions to the Reuse Problem
Software reuse is a vital issue in successful development of large software systems. Software reuse can reduce development effort and maintenance costs. Thus, much effort in software engineering techniques has been devoted to the problem of creating reusable software.

The techniques for developing reusable software have evolved through several generations of language features (e.g., structured programming, functional programming, 4GLs, object-oriented programming), compilation tools (e.g., source file inclusion, compiled object files, class libraries, components),
