The support tool for highly reliable component-based software development

We discuss a support tool for highly reliable component-based software development. The tool assures the high reliability of the output by verifying refinement and by generating connectors. The advantages of the tool are automated refinement verification and automated connector generation. As a software architecture for component-based software, we select the tree architecture, in which components are represented by a projection-style behavioral specification. The input of the tool is: (a) a requirement specification of the target software, (b) a refined specification specifying how to combine the components, and (c) the components themselves. (a) and (b) are projection-style behavioral specifications, while (c) are JavaBeans. The output of the tool is JavaBeans that are obtained by combining (c) and the generated connectors.
