In JBoss, we can configure multiple security realms, we can have multiple applications and each application can use different security realm.
We are able to mention realm name in security-domain element in jboss-web.xml in our application
In weblogic, websphere also we can create multiple security realms, but only one realm can be active realm. And all applications will use that same realm. I believe that there is no way to use different realms for different applications.
I googled long time, and I could not find equivalent element(for security-domain) in weblogic and websphere. And their forums also poor.
Is it possible in weblogic, websphere? I believe that JBoss server developers might know this(firstname.lastname@example.org, email@example.com firstname.lastname@example.org, and many). Please tell me,
If not, what is the use of enterprise products, platforms, jrocket, ibm jdk, studio, ...
No, I don't know. Security is the least defined aspect of Java EE so it will have the most variance between vendors.
