Content in Web 2.0 application is the combination of information from other sources and components. However, existing Web 1.0 applications have not capable to provide information and components to create Web 2.0 application. In this paper, the authors propose a methodology having these features: trains wrappers (WebBot) having ability to extract information from websites
parameterizes input before executing WebBot, executes WebBot to extract on demand information and expose this information through web services. With the propose approach, the system can easily turn websites into information sources, recombine information into a new source and export information to web services with common technologies (SOAP, REST).
