Class ApplicationServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

org.tentackle.web.misc.ApplicationServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class ApplicationServlet
extends javax.servlet.http.HttpServlet

RMI HTTP-tunneling servlet.

The servlet can operate in two modes:

1. If the servlet parameter "applicationServer" is given the servlet will start an server application. All servlet parameters are converted to server properties, so there's no need for an extra property file. However, the "tentackle.properties" is supported via <env-entry> as in WebApplication.
2. If thers is no such servlet parameter the servlet will only forward RMI requests.

The logger can be set by the servlet parameter "logger". If not set the default logger will be used.
