Hi Daniel, the restriction for the "web" tier to not call the "data" tier may be accomplished with firewall/network rules, as wildfly is not able to prevent any deployed application to open a network connection to any host. Wildfly may make it a bit difficult by restricting which modules the application developer can use, but that is not safe.
Hi Claudio... Thanks for your response! Its restricted for a reason... The purpose of this is to split the stack not create a pin hole through the layer:
Web > API > Data
So were trying to abstract the web ui from the api so they are separate... I have seen bits of information on this but nothing solid enough for me to develop on and unfortunately I dont have vast experience with JBoss
