Thanks in advance to all the responders. I have four apps that runs on the same jboss instance. I would like to know if there´s a way to set priorities, or resources, for each of them. For example: One of the apps is a auction system, and it has a SLA with the customer. During the period of auctioning, the others apps should not interfere in the response time of the auction system. In this cenario I would like to set greater priority to the auction system. Like in operating system realm, that you can change the priority of the processes. I expect to have been more clear. My question is not class loading related. Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4176503#...
