The exception is related to use of weld:
org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active
contexts for scope type javax.enterprise.context.RequestScoped
which is only a symptom. There may be a different issue behind it. See
the description of the issue.
Issue 11504 is about jsf login page.
Issue 12642 is related to usage with JSR 196,
https://glassfish.dev.java.net/issues/show_bug.cgi?id=12642, which is
fixed in 3.1_b12.
Are you in the latter case?
If you are not in the above two scenario, then we need to isolated the
scenario, file a new issue and attached a test case there.
