1 V ukázkovém příkladu je popsán základní způsob konfigurace webové aplikace v Javě pomocí [[Java Apereo CAS Client>>https://github.com/apereo/java-cas-client]]. Aplikace je schopna získat přihlášeného uživatele pomocí CAS v3 protokolu.
2
3 1. Do webové aplikace je potřeba přidat knihovny klienta https://mvnrepository.com/artifact/org.jasig.cas.client/cas-client-core buď přímo a nebo pomocí nějakého buildovacího nástroje např. Maven.(((
4 {{code language="xml"}}
5 <dependency>
6 <groupId>org.jasig.cas.client</groupId>
7 <artifactId>cas-client-core</artifactId>
8 <version>3.5.1</version>
9 </dependency>
10 {{/code}}
11 )))
12 1. Nakonfigurovat ##web.xml##. V uvedené konfiguraci je nutné nahradit adresu klienta https://klient.vsb.cz s URL našeho serveru. V mapování filtru ##CAS Authentication Filter## je možné uvést místo ##/*## kontext do chráněné zóny aplikace např.(((

164 1. Pro odhlášení uživatele z CAS je potřeba přistoupit na url ##https:~/~/www.sso.vsb.cz/logout##.(((
165 Před odhlášením z CAS je vhodné zrušit session v aplikaci klienta (zaleží to však na konkrétním klientu).
166
167 Pokud po odhlášení z CAS nechceme aby uživatel zůstal na odhlašovací stránce CASu, můžeme k odhlašovací url přidat parametr 'service', který
168 obsahuje url (nejlépe zakódovanou pomocí URL kódování) na kterou se má po odhlášení přesměrovat. Url musí obsahovat adresu, která je pro službu povolena.
169
170 např. ##https:~/~/www.sso.vsb.cz/logout?service=https%3A%2F%2Fklient.vsb.cz##
