An adapter can be deployed into a system in a single step without recycle. An adapter can contain components, such as an integration adapter, event router, and resource adapter, which all conform to a given specification such that these components use some of the same classes. A class loader allows these components to share common classes, instead of having separate classes. A single Enterprise archive file contains files necessary to deploy the adapter, such as Web archive files, resource adapter archive files, event router Web application files, and shared Java archive files. The inclusion of these files in an Enterprise archive file allows all components for the adapter to be deployed in a single step without the need to recycle.This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
