I think you should ask in the CAS-DEV mailing list about this topic, anyway this is my what I did for the same problem.
If you search in cas-servlet.xml, you'll see that class for the bean dynamicRedirectViewSelector is org.jasig.cas.web.flow.DynamicRedirectViewSelector.
This is the original method that you have to modify in the class DynamicRedirectViewSelector :
public ViewSelection makeEntrySelection(final RequestContext request) {
final WebApplicationService service = WebUtils.getService(request);
final String ticket = WebUtils.getServiceTicketFromRequestScope(request);
final Response serviceResponse = service.getResponse(ticket);
switch (serviceResponse.getResponseType()) {
case POST:
final Map<string, object> model = new HashMap<string, object>();
model.put("parameters", serviceResponse.getAttributes());
model.put("originalUrl", service.getId());
return new ApplicationView("postResponseView", model);
default:
return new ExternalRedirect(service.getResponse(ticket).getUrl());
}
}
</string,></string,>
I my case, I debbuged the execution and my response type is never POST, so my execution go always for default
I change the default case of the switch:
default:
// original code
//return new ExternalRedirect(service.getResponse(ticket).getUrl());
/*
*Customized code for redirect the url to the top window.
*/
final Map<string, object> modelAux = new HashMap<string, object>();
modelAux.put("service", service.getResponse(ticket).getUrl());
return new ApplicationView("redirectView", modelAux);
</string,></string,>
I created a new view in WEB_INF/classes/protocol_view.properties
I added to the end of the file
### Redirect View
redirectView.(class)=org.springframework.web.servlet.view.JstlView
redirectView.url=/WEB-INF/view/jsp/protocol/redirect.jsp
And this is my redirect.jsp
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script type="text/javascript">
function redirect(){
window.top.location.href = document.redirect.service.value;
}
</script>
<form name="redirect" action="">
<input type="hidden" name="service" id="service" value="${service}">
</form>
Recapping,
You have to:
Customize the org.jasig.cas.web.flow.DynamicRedirectViewSelector.
Create a new cas-server-corexxxx.jar and overwrite the old one (you'll find it in WEB-INF/lib)
Modify WEB-INF/classes/protocol_view.properties for adding your new view
Create the new view
Create the new cas-web.war
Deploy it
Hope it Helps!
