[infinispan-issues] [JBoss JIRA] (ISPN-4499) Prevent shadowing user-defined jgroups configuration file

Prevent shadowing user-defined jgroups configuration file --------------------------------------------------------- Key: ISPN-4499 URL: https://issues.jboss.org/browse/ISPN-4499 Project: Infinispan Issue Type: Enhancement Components: Configuration Affects Versions: 7.0.0.Alpha4 Reporter: Martin Gencur Assignee: Martin Gencur Fix For: 7.0.0.Alpha5 When users create their own JGroups configuration file and name it the same way as default configuration files (jgroups-udp.xml / jgroups-tcp-xml / jgroups-ec2.xml), they might not be visible to the user application as they're shadowed by the default configuration files. Proposed solution: * place current jgroups configuration files into META-INF/configs folder (this folder doesn't have to have an obscure name such as "_internal" because of the following two points which complement the solution) * define order in which the config files are read by class loader (i.e. first scan user application, then path under META-INF/configs) * when Infinispan is started, log the path to the configuration file used, e.g.: {code} 2014-06-12 06:45:02,871 [thread-name] INFO [package-name] Using JGroups configuration file 'jar:META-INF/example_configurations/jgroups/udp.xml' 2014-06-12 06:45:02,871 [thread-name] INFO [package-name] Using JGroups configuration file 'file:/app_home/config/jgroups-udp.xml' {code}
