have a servlet that reads the configfile at servletengine startup
(specified in web.xml for tomcat), have that servlet read the config
variables into public static variables
eg:
class ConfigServlet {
public static String dbDriver;
public static String dbName;
init () {
read variables from configfile
}
class TheBean {
Class.forName(ConfigServlet.dbDriver);
Connection con =
DriverManager.getConnection(ConfigServlet.dbName,"", "");
and so on...
}
this is how i did it, comments are welcome
