Subject RE : RE : RE : RE : RE : RE : how to access Subject after authent ifica tion
Date Mon, 26 Jul 2004 15:22:14 GMT
Now i can access to the subject (thanks to Jean Francois and Matt)!!
In my use case, tomcat uses jaas (and specific login module) first to
authenticate users (it runs)... and secondly to authorize the access to
resources (EJB) deployed in weblogic server.
I use weblogic API to propagate implicitly the subject (or principals)
information from tomcat to weblogic, and use j2ee roles to secure access to
resources.
At this stage, i get the exception :
[java.io.NotSerializableException:
org.apache.catalina.realm.GenericPrincipal]...
caused because the GenericPrincipal in Catalina isn't serializable.
Somebody (or Craig R. McClanahan, the author) could explain for which reason
this class is not serializable.
Thanks.

I never used JAAS this way so I cannot help you. Are you trying to load 
the file from your webapp? Hav eyou try  to put the file inside the war?
