When I put the web.xml in my overlay (exact copy of the one in cas-server-webapp) I get the following error when I try and log in:

Any ideas what would cause this?

Bryan,

I can help you understand what the stack trace is saying, but I don't know why this problem is happening in your local environment without looking at your web.xml and local Spring configuration files.



web.xml declares a character encoding filter.

    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>


The Java Servlet Filter class that your servlet container (apparently, GlassFish) instantiates is a generic Spring-provided Filter (DelegatingFilterProxy) that then delegates to a bean wired up by Spring.  What bean? The bean with the same name as the filter.  So, the bean named "characterEncodingFilter".

Web.xml declares the listener that does this wiring and enumerates the (locations of) Spring configuration files.

	<listener>
		<listener-class>
			org.jasig.cas.web.init.SafeContextLoaderListener
		</listener-class>
	</listener>


	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			/WEB-INF/spring-configuration/*.xml
			/WEB-INF/deployerConfigContext.xml
		</param-value>
	</context-param>




What this stack trace is telling you is that there is no such bean named "characterEncodingFilter".

characterEncodingFilter is normally declared in /WEB-INF/spring-configuration/filters.xml

    <bean id="characterEncodingFilter" class="org.springframework.web.filter.CharacterEncodingFilter"
            p:encoding="UTF-8"
            p:forceEncoding="true" />


https://source.jasig.org/cas3/tags/cas-server-3.4.5/cas-server-webapp/src/main/webapp/WEB-INF/spring-configuration/filters.xml



So, at least one of these problems should be it:
1) your filters.xml does not declare  bean characterEncodingFilter.
2) your filters.xml does not exist at all (neither coming from the cas-server-war you're Maven overlaying upon nor coming from your local configuration)
3) your web.xml contextConfigLocation int-param is such that the paths or explicit files it enumerates doesn't include your filter.xml


As for how this is supposed to work: filters.xml is supposed to be coming from the war you're overlaying upon, such that you need do nothing and this Bean is just present and accounted for automatically.

Best wishes,

Andrew

Thanks Andrew,

 

I have fixed the problem, but it doesn't really make any sense. I simply copied BOTH filters.xml and web.xml to my overlay and now everything works.

 

This has me really scratching my head, but I am not inclined to dig deeper as it works now.

 

Cheers,

 

Bryan
