eXtremeVista is a Mainframe-to-Web development tool that enables organizations to rapidly transition to e-business by capturing core business logic embedded in mainframe applications and securely extending those applications to thousands of Web-based users. eXtremeVista creates Java objects that can be deployed in a variety of forms to any compliant server. Web-based applications can then access legacy data by calling these Java objects which securely retrieve information from the mainframe.
