Hi everyone!
I am trying to integrate Acegi security into a web application using the Spring framework. The application runs fine initially. If I add a definition for the filterChainProxy in the Spring's applicationContext.xml, the application failed to be deployed properly, i. e., the application is no longer accessible with a Tomcat 404 status. Here is what i have tried to add in the xml file:

<bean id="filterChainProxy" class="net.sf.acegisecurity.util.FilterChainProxy" >
<property name="filterInvocationDefinitionSource">
<value>
CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
PATTERN_TYPE_APACHE_ANT
</value>
</property>
</bean>

Pls corret me if I'm wrong, I think this piece of code does not depend on any other beans. I am trying to add it just to know if a simple Acegi bean definition would not cause errors. Unfortunately, it does. Can anyone help me out with this problem? Thanks in advance!
By the way, I have the Acegi 0.8.3
