JNDI Lookup Andre EJB’er Ressurser (JCA, JDBC, JMS, Web. Services) Transaksjoner (fra klient) Navn

Sikkerhet • Autorisasjon • Rollebasert: web, ejb ressurser kan settes til å kreve en rolle • Programmatisk: Context. is. User. In. Role, Context. get. Caller. Principal • Context ”propagation” • Autentifikasjon • Servlets har innebygget støtte for login (bruker JAAS) • Klient autentiserer seg gjennom Login. Context (JACC) • Egen JAAS mekanisme: Implementer javax. security. auth. spi. Login. Module (2 fase) Copyright © 2003 Systek AS brodwall@systek. no
