I've got some problem in my Sun Application 9.1 configuration. When I want to dispatch to another page from my Servlet I encounter this Error (HTTP Error 404.)
I've searched plenty in internet and finally I arrived at this result.
My problem was in HOME/WEB-INF/web.xml configuration. I should add this tags in order to control this error

<filter>
        <filter-name>Agent</filter-name>
        <filter-class> com.sun.identity.agents.filter.AmAgentFilter </filter-class>
</filter>
<filter-mapping>
      <filter-name>Agent</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>ERROR</dispatcher>
 </filter-mapping>

while i was thinking that my problem has been solved but i faced to another problem.


"com.sun.identity.agents.filter.AmAgentFilter" now this is the main problem:
How can I get this file?

I downloaded "j2ee_agents" to get access AmAgentFilter.

but now i have 2 questions
1. dose it really need to have this application "j2ee_agents" to solve my problem?
2. when I tried to install this software on my system i encounter another problem.
the application asks me what is your "Access Manager Host::"
what should i answer to this question?
