Configure Servlet

This section explains how to configure Servlet(using PageMixer) corresponded to JSP file(using Struts TagLib).

Overview

Class names

In this tutorial, abbreviated class names are used. Complete names are shown below.

Classes of PageMixer framework

PageServlet again

How to use/configure PageServlet and classes derived from it is explained in "Mixing with Servlet".

PageMixer also provides classes derived from PageServlet to use MonoPage, LocalePage, DefaultPage and I18NDefaultPage for using in Struts environment. They are named as MonoPageServlet, LocalePageServlet, DefaultPageServlet and I18NDefaultPageServlet, too, but are placed in jp.ne.dti.lares.foozy.pagemixer.struts package.

Describe web.xml

Configuration example of the Servlet instead of mainMenu.jsp is shown below. This example uses LocalePageServlet for locale sensitive response renderring, even though you can choose MonoPageServlet to render response locale in-sensitively.

<servlet>
  <servlet-name>
    mainMenu.page
  </servlet-name>
  <servlet-class>
    jp.ne.dti.lares.foozy.pagemixer.struts.LocalePageServlet
  </servlet-class>
  <init-param>
    <param-name>
      forward.condition.0
    </param-name>
    <param-value>
      pagemixer.servlet.NotLoginCondition
    </param-value>
  </init-param>
  <init-param>
    <param-name>
      filter.factory.0
    </param-name>
    <param-value>
      pagemixer.filter.UserFilter$Factory
    </param-value>
  </init-param>
  <init-param>
    <param-name>
      page.location
    </param-name>
    <param-value>
      page.mainMenu
    </param-value>
  </init-param>
</servlet>

    :

<servlet-mapping>
  <servlet-name>
    mainMenu.page
  </servlet-name>
  <url-pattern>
    /mainMenu.page
  </url-pattern>
</servlet-mapping>

"NotLoginCondition" forwards control to "login" page, when /mainMenu.page is accessed without authentication. But where should this forward control? where is "login" action?

In PageMixer/Struts co-operation demonstration, "path.logon" context-param is used to tell the location of "login" action to all NotLoginConditions in demonstration of co-operation with Struts, even though you can embed location of "login" page in NotLoginCondition code directly.

<context-param>
  <param-name>
    path.logon
  </param-name>
  <param-value>
    /logon.page
  </param-value>
</context-param>

This allows you re-configure web application without compilation.

Please see "Mixing with Servlet" for detail about the other init-params.
