I added a "domain" field to the CAS login page. For testing I used an input
text field in which the user had to specify a hardcoded value.
Now I want to replace the text field with a selection list (of domains) which
is put together when the user has entered his username and
leaves the username field (jquery onBlur). In the onBlur callback I want to
make a Ajax call to a servlet/controller/..
I tried with a servlet registered in web.xml which I first tried to run
directly in the address bar:
https://(machinename):11143/cas/domsecservice/userdomains?username=(username)&role=ROLE_DOMAIN_USER
However, this is always redirected to https://(machinename):11143/cas/login?...
I really don't know how to handle this. Do I have to create a mvc controller?
Do I have to add this to cas-servlet.xml or to web.xml? Or ...?
This is the controller I created but I do not how to access it in the Ajax call
or how to configure it.
