Re: Additional validation for j_security_check action

[Juanjo C <jj...@gmail.com>]

Sorry for use this thread, but I'm desperate....

Dani, How to use Struts 2 with JAAS? I have my own implementation of JAAS
that works fine in applications without Struts, but don't works if I use it
into Strust.....

Can you help me?
