Hi All Is it right to think assumption at below? Whenever a war file is deployed, JBoss application server's class loader loads the class which implements ServletContext then trigger the ServletContextEvent. Before all operation above, I assume that all configurations(web.xml, jboss-aop.xml, application.xml or vs) are read. Therefore AOP advices/interceptions even on ServletContext implementation will be vlid as firstly config is read then initialization is done. What could happen if more than web applications are deployed on same jboss instance? Would Class file of ServletContext implementation be loaded per class loader assigned to war file or same loaded class be used every war file? (What kind of class loading hierarchy is there??)
