Hello,
   We use JBoss Rules 4.0.7  in a commercial project.  But in order to link the drools UI with our own UI, we need to add  a login page and modify the web.xml to the drools-jbrms.war. 
   Is it legal for us to this in a commercial project?
   And we have noticed that the drools is under ASL 2.0, does its dependencies are also under this license?
 
Thanks!
