Hello,
i have a funny problem, maybe someone can bring a bit light into this:
I`m using DataSourceRealm for security and thanks to the list this is working
fine now.
Right now i want to access the principal inside the application with
Principal principal = request.getUserPrincipal();
so far so good. But
principal.getClass().getName() returns
"org.apache.catalina.realm.GenericPrincipal"
while
principal is instance of "javax.security.Principal".
Also i get java.lang.ClassCastException:
org.apache.catalina.realm.GenericPrincipal
when trying this:
GenericPrincipal gPrincipal = (GenericPrincipal) principal;
In in /META-INF/context.xml i defined <Context privileged="true">.
Regards Oliver
