Exception in RealmBase - Possible Bug

[mduffy_lists]

Searching various archives, I found two similar issues from earlier this year that were unanswered:

http://www.mail-archive.com/[e-mail]/msg131837.html//www.mail-archive.com/[e-mail]/msg131837.html
http://www.junlu.com/msg/44667.html

Basically, there is an exception at startup when using a custom realm implementation (in my case I am using Security Filter: http://securityfilter.sourceforge.net)

Here is the exception:

03:42:59,976 INFO [RealmBase] Parent not available yet: null:type=Engine
03:42:59,983 ERROR [RealmBase] Can't register null
java.lang.NullPointerException
at org.apache.catalina.realm.RealmBase.init(RealmBase.java:1194)
at org.apache.catalina.realm.RealmBase.start(RealmBase.java:875)
at org.apache.catalina.realm.JDBCRealm.start(JDBCRealm.java:669)

Thx.

Has anyone been able to implement any type of filter without getting this bug?

You could declare a custom Realm in a WEB-INF/context.xml file.

But why would you need to use the Security Filter project? With JAAS is more than enough.
