The invention utilizes automated processing to generate Java-based programming elements, such as Data Access Objects (DAOs), in order to facilitate a conversion from use of a first database-access application to a second database-access application. A different Java-based programming element may be generated for each query text file of the first application, where the Java-based programming elements are compatible with execution of the second application. For queries that include value placeholders that are provided to accommodate dynamic input of values during operation of the first application, the automated processing includes mapping the value place-holders and other query parameters to the Java-based programming elements.
