I have a web app that serves images to a client. I want that these images are put in the cache. My idea is to run Jboss in order to manage the cache and Tomcat in front of JBoss to put and retreive images.
Could it be possible?

Could you explain me the reason of the example at chapter 8.2.1? I have copied and adapted this example?

I also try to deploy my webapp in Tomcat inside JBoss and i have also an exception
