Thanks Matt for your suggestion.
In the end I got it working without touching the web flow xml file.
In the AuthenticationHandler I have modified the service url by adding my new
parameter "s". Since "service" is a
org.jasig.cas.authentication.principal.SimpleWebApplicationServiceImpl object
and I cannot overwrite the id and orinalUrl, I have created another object of
this class with my url with the new parameter added:
RequestContext rc=RequestContextHolder.getRequestContext();
WebApplicationService was=WebUtils.getService(rc);
String newurl=(String)was.getId();
newurl=newurl+"?s="+s;
WebApplicationService wasnew=new
SimpleWebApplicationServiceImpl(newurl);
rc.getFlowScope().put("service", wasnew);
Thus, if you enter the following url
https://localhost:8443/webapps/CampusLauncherJava/prueba.jsp
you will be redirected to the CAS login page:
https://localhost:8443/cas/login?service=https%3A%2F%2Flocalhost%3A8443%2Fwebapps%2FCampusLauncherJava%2Fprueba.jsp
and once you have logged in you will be redirected to the original url with the
added parameter.
https://localhost:8443/webapps/CampusLauncherJava/prueba.jsp?s=c4
It is a pitty that the name of the service parameter is not exposed as a public
constant I have to put directly in my handler.
