         <your doc root>/WEB-INF/classes/db.properties
       • Change directory to  <your doc root>/WEB-INF/classes/
       • Make sure that the Cloudscape .jar files are in the classpath.
       • Run java db.OscarDB
    2. Install cloudscape.jar in Tomcat.
       • Copy the  file cloudscape.jar to the directory
         <tomcat home>/lib/
