dinamica.Controller
| Controller | | public class Controller extends HttpServlet (Code) | | Central controller to dispatch all requests
recevied by a Web Application built with this framework.
This class represents the Coordinator of all activities in
the application, it is the base for the advanced MVC mechanism implemented
by this framework. This servlet should be configured in WEB.XML to intercept
requests targeting /trans/... URLs.
The application template provided with the framework includes all
the required configuration settings in WEB.XML, use that as a starting
point for your own applications.
Please read the Howto documents and technical articles included with
this framework in order to understand and master the inner working mechanisms
of the framework and the role of this servlet in particular.

Solves sporadic Class not found exceptions when running with Resin 2.1.14 + IBM JDK 1.4.2.
This method attempts to use context class loader, if fails it will use Class.forName().
Parameters:
className - Name of class to load - include full package name New instance of the class
throws:
Throwable - (ClassNotFound exceptions) |
| init | | public void init() throws ServletException(Code) | | Controller initialization tasks.
Reads parameters jndi-prefix and def-datasource
and creates a default datasource object with
modular scope to be used by all threads from this servlet
|
| replaceMacros | | String replaceMacros(HttpServletRequest req, String xmlData) throws Throwable(Code) | | Replace markers like ${def:actionroot} in config.xml
Parameters:
req - Request object
Parameters:
xmlData - Body of config.xml Body of config.xml with all markers replaced by the corresponding values
throws:
Throwable - |
| saveLog | | void saveLog(String message)(Code) | | Save message to filesystem, using the context parameter
log-file defined in web.xml and stored in modular variable _logFile
Parameters:
message - String to append to file |
| validateInput | | Recordset validateInput(HttpServletRequest req, Config config, Connection conn, boolean jdbcLog, PrintWriter jdbcLogPrinter) throws Throwable(Code) | | Auto-Validate request parameters for single value
parameters - array parameters must be processed
