I guess you are right, I'll add the check for null realm mapping.
TC> How do I go about rectifying this?
You should specify realm mapping and authentication module in
container-configuration either for each jboss.xml or globally, in
conf/default/standardjboss.xml, e.g.:
<authentication-module>java:/jaas/other</authentication-module>
<role-mapping-manager>java:/jaas/other</role-mapping-manager>
where "other" corresponds to a section in conf/default/auth.conf.
jBoss distribution contains two JAAS server login modules:
org.jboss.security.SimpleServerLoginModule and
org.jboss.security.DatabaseServerLoginModule,
and you would probably wish to write your own.
Also it is possible to go without JAAS at all. Then you should use
security MLETs specified in jboss.conf, either existing
org.jboss.security.SimpleRealmMappingService and
org.jboss.security.EJBSecurityManagerService
or write your own.
In this case jboss.xml could contain
<authentication-module>java:/EJBSecurityManager</authentication-module>
<role-mapping-manager>java:/SimpleRealmMapping</role-mapping-manager>
Best regards,
Oleg
