Hello There is a file: standardjboss.xml This file contains JBoss configuration. But there is a posibility to override some properties by adding element <container-configurations> to jboss.xml file from META-INF of our archive, example: <jboss> | <enterprise-beans> | ... | </enterprise-beans> | <container-configurations> | <container-configuration extends "(name of proper configuration)"> | <container-pool-conf> | <MaximumSize>2</MaximumSize> | <strictMaximumSize>true</strictMaximumSize> | </container-pool-conf> | </container-configuration> | </container-configurations> | </jboss> | This example will change pooling configuration. And here i have some questions: This configuration is written in jboss.xml file. Does this mean that configuration will be overridden only for beans in this specific archive? Lets suppose i have an application contains 5 jar files. Configuration is overridden in only one jboss.xml file. This configuration sets new pooling properties for stateless session beans, but i have stateless session beans in all 5 jar files. So deas this mean that specific configuration will be in force only for beans from this one jar file? Thank you for your reply in advance :) vitor_b View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4025749#...
