It became important to develop a wrapper for web information sources due to prevalence of information services through web information sources. We present a wrapper prototype that is a middleware to integrate web information sources. We present the derivation strategy of XML Schema from HTML documents and the query processing method based on XQJ. The usage example of wrapper API will show the usefulness of our prototype system.
