wicket.protocol.http.servlet
Class WicketSessionFilter

java.lang.Object
  wicket.protocol.http.servlet.WicketSessionFilter

All Implemented Interfaces:

javax.servlet.Filter

public class WicketSessionFilter
extends java.lang.Object
implements javax.servlet.Filter

This filter can be used to make the Wicket WebSession instances available to non-wicket servlets.

The following example displays how you can make the Wicket session object of application SessionApplication, mapped on /sessiontest/* available for servlet WicketSessionServlet, mapped under /servlet/sessiontest:

    <filter>
      <filter-name>WicketSessionFilter</filter-name>
      <filter-class>wicket.protocol.http.servlet.WicketSessionFilter</filter-class>
      <init-param>
        <param-name>servletPath</param-name>
        <param-value>sessiontest</param-value>
      </init-param>
    </filter>
   
    <filter-mapping>
      <filter-name>WicketSessionFilter</filter-name>
      <url-pattern>/servlet/sessiontest</url-pattern>
    </filter-mapping>
   
    <servlet>
      <servlet-name>SessionApplication</servlet-name>
      <servlet-class>wicket.protocol.http.WicketServlet</servlet-class>
      <init-param>
        <param-name>applicationClassName</param-name>
        <param-value>session.SessionApplication</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
    </servlet>
   
    <servlet>
      <servlet-name>WicketSessionServlet</servlet-name>
      <servlet-class>session.WicketSessionServlet</servlet-class>
      <load-on-startup>1</load-on-startup>
    </servlet>
   
    <servlet-mapping>
      <servlet-name>SessionApplication</servlet-name>
      <url-pattern>/sessiontest/*</url-pattern>
    </servlet-mapping>
   
    <servlet-mapping>
      <servlet-name>WicketSessionServlet</servlet-name>
      <url-pattern>/servlet/sessiontest</url-pattern>
    </servlet-mapping>
 

After that, you can get to the Wicket session in the usual fashion:

 wicket.Session wicketSession = wicket.Session.get();
