Programatic JAAS login in Tomcat 6.0.26!

[neo21 zerro]

Hello, 


   I'm using Tomcat 6.0.26 and java 1.5 SDK and I'm trying to implement a 
programmatic login in tomcat. 
   I'm using JAAS for the container based security. Is there anyone that has 
done this before? 
   I've tryied to bypass it by making  a post with the username and the 
password 
in           this request 
http://localhost:8080/acm/flex/j_security_check&username=test&password=test but 
it seems that Tomcat caches this request and then expects another request. I 
don't know what else to do.




   Please help!


 
    Thanks!!!
