Help, Security !

[Abib Rahjameran]

I am a newbie to Spring Security and am getting the following error when starting TomCat:

SEVERE: Exception starting filter Acegi Filter Chain Proxy
javax.servlet.ServletException: targetBean 'filterChainProxy' not found in context at org.acegisecurity.util.FilterToBeanProxy.doInit(Fi lterToBeanProxy.java:126)

Here is my config in web.xml:
<filter>
<filter-name>Acegi Filter Chain Proxy</filter-name>
<filter-class>
org.acegisecurity.util.FilterToBeanProxy
</filter-class>
<init-param>
<param-name>targetBean</param-name>
<param-value>filterChainProxy</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>Acegi Filter Chain Proxy</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

And my security.xml:
<bean id="filterChainProxy"
class="org.acegisecurity.util.FilterChainProxy">
<property name="filterInvocationDefinitionSource">
<value>
CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
PATTERN_TYPE_APACHE_ANT /**=httpSessionContextIntegrationFilter,
formAuthenticationProcessingFilter,
exceptionTranslationFilter,filterSecurityIntercept or
</value>
</property>
</bean>

Any ideas as to what I am doing wrong?

Thanks.
