[anikgnr]

Here is our filter list in web.xml:

        <filter-mapping>
        <filter-name>GTCErrorHandler</filter-name>
        <url-pattern>/GTCProxy/failure/*</url-pattern>
    </filter-mapping>

        <filter-mapping>
                <filter-name>UrlRewriteFilter</filter-name>
                <url-pattern>/*</url-pattern>
        </filter-mapping>
    
        <filter-mapping>
                <filter-name>Servlet Pipeline Filter</filter-name>
                <url-pattern>/*</url-pattern>
                <dispatcher>REQUEST</dispatcher>
                <dispatcher>INCLUDE</dispatcher>
                <dispatcher>FORWARD</dispatcher>
        </filter-mapping>
                              

    <filter-mapping>
           <filter-name>richfaces</filter-name>
           <url-pattern>/*</url-pattern>
           <dispatcher>REQUEST</dispatcher>
           <dispatcher>FORWARD</dispatcher>
           <dispatcher>INCLUDE</dispatcher>
    </filter-mapping> 
       
    <filter-mapping>
                <filter-name>Seam Filter</filter-name>
                <url-pattern>/*</url-pattern>
                <dispatcher>REQUEST</dispatcher>
                <dispatcher>FORWARD</dispatcher>
        </filter-mapping>

        <servlet>
                <servlet-name>Faces Servlet</servlet-name>
                <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
                <load-on-startup>1</load-on-startup>
        </servlet>
 
        <servlet-mapping>
                <servlet-name>Faces Servlet</servlet-name>
                <url-pattern>*.seam</url-pattern>
        </servlet-mapping>

    <context-param>
          <param-name>facelets.DEVELOPMENT</param-name>
          <param-value>false</param-value>
    </context-param>

I have switched off the seam debug mode in components.xml

here is my pages.xml:

    <exception class="org.jboss.seam.security.AuthorizationException">       
        <http-error error-code="404"/>       
    </exception>
    <exception class="org.jboss.seam.security.NotLoggedInException">
        <http-error error-code="404"/>       
    </exception>
    <exception class="org.jboss.seam.InstantiationException">       
        <http-error error-code="404"/>       
    </exception>   
    <exception class="java.lang.NullPointerException">       
        <http-error error-code="404"/>       
    </exception>   
    <exception class="java.lang.Exception">     
        <http-error error-code="404"/>       
   </exception>

I have generated AuthorizationException and NullPointerException, I can see the error on my stack trace but unfortunately pages.xml is not capturing those.

I am sure I have missed something. Please suggest me what should i do now ?
