Hi there,
With overlay, we supposed to be able to upgrade to CAS new version with a
change in POM. But in reality, it takes more than that.
1. I need to extend login webflow, so I made a copy of login-webflow.xml
and start making changes and additions. I do not think overlay will take
some from the original CAS login-webflow.xml and some from my
login-webflow.xml and combine them.
2. For the same reason, I had to copy cas-servlet.xml because I want to add
a subflow in login flow, and all I had to change is this line:
<webflow:flow-registry id="loginFlowRegistry"
flow-builder-services="builder" base-path="/WEB-INF/webflow">
<!-- my customization, allow subflow in sub-directory -->
<webflow:flow-location-pattern value="/login/**/*-webflow.xml"/>
</webflow:flow-registry>
<!-- declare our own handler so that we can add additional exceptions -->
<bean id="authenticationExceptionHandler"
class="org.jasig.cas.web.flow.CASAuthenticationExceptionHandler" />
However, I donot know how to extend cas-servlet.xml without making a copy
and directly changing the copy, let Maven completely override the original
cas-servlet.xml in CAS source.
3. if I add a new filter, then I have to copy web.xml and add filter
definition.
Next time, I upgrade CAS, I have to do the same process. Copying these
files from CAS source, making changes to them.
Is there a better way?
Thx,
Yan
