Class ModulesServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

org.wandora.modules.servlet.ModulesServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class ModulesServlet
extends javax.servlet.http.HttpServlet

A HttpServlet that sets up the modules framework. This is the actual servlet implementation that the servlet container interfaces with. It sets up the modules framework at servlet initialisation and adds some basic modules into it before loading the configuration file and initialising all other modules. It sets a root ServletModule, with the module name rootServlet, so that actions can then interface with the actual servlet container. It also sets the variable servletHome to what should be the WEB-INF directory of the webapp. After this, it loads the modules framework configuration file from a file specified in the servlet configuration init parameter modulesconfig. If not specified, it tries modulesconfig.xml as the default value.
