how to write a login form use acegi ? what's wrong with me?

the requested resource (/j_acegi_secuity_check) is not available.

why?


I copy it from example and paste it in my config document.

I only found 4 "j_acegi_security_check" in the files;
web.xml
applicationContext-acegi-security.xml
acegilogin.jsp


==================================
<bean id="authenticationProcessingFilter" class="net.sf.acegisecurity.ui.webapp.Authenticati onProcessingFilter">
<property name="authenticationManager">
<ref bean="authenticationManager" />
</property>

<property name="authenticationFailureUrl">
<value>/acegilogin.jsp?login_error=1</value>
</property>

<property name="defaultTargetUrl">
<value>/</value>
</property>

<property name="filterProcessesUrl">
<value>/j_acegi_security_check</value>
</property>
</bean>

Is your AuthenticationProcessingFilter defined in web.xml? It's a filter that detects the post to j_acegi_security_check and wil process the authentication attempt.
