websso-3.0.5 and webflow problem

Hi,

I am using cas-3.0.5 server. I have installed it on Weblogic 9.1.

It works fine on 3 of our servers (exactly the same war file)
 but when I installed it on the another identical server (main
production server), as soon as the client points to the login page, I
get the following error  in the logs (specified in the end) .

I can see in project.xml the spring-webflow version 1.0-rc3 is being used.

and in cas-servlet.xml flowRegistry is configured as

<bean id="flowRegistry"
       class="org.springframework.webflow.registry.XmlFlowRegistryFactoryBean">
        <property name="flowLocations" value="/WEB-INF/login-webflow.xml"/>
</bean>

but in spring-webflow version 1.0-rc3  XmlFlowRegistryFactoryBean is
at org.springframework.webflow.engine.builder.xml.XmlFlowRegistryFactoryBean.

When I changes the config to this path, and tested on one of the
servers where it worked earlier, and it failed.

Where is XmlFlowRegistryFactoryBean  resolved from ?

The Error that I get is something to do with class loading?

Any help will be appreciated.
