Working on an application using log4j and deployed in WebSphere, we had the need to output the logs on the SystemOut.log and SystemErr.log files. In WebSphere with the normal configuration it outputs all the logs in the SystemOut.log. We wanted only the ERROR and WARN level logs redirected to the SystemErr.log file, so we used the configuration below for the log appenders. log4j.properties ######################################## # LOG4J-properties ######################################## # This is the configuring for logging displayed in the Application Server log4j.rootCategory=DEBUG, stdout, stderr log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Threshold=DEBUG log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=[%-5p] %t (%d{dd/MM/yy HH:mm:ss}) %c {1} - %m\n log4j.appender.stdout.filter.filter1=org.apache.log4j.varia.LevelR...

This is the first part of a post about message bundles. Having to work on applications requiring support for different languages I had the need to have a message bundle retrieving the translation from a DB. With a  DB was easier to update labels not correctly translated without the need of restarting the application. We are going to build a service providing the functionality to store and retrieve localized messages from a database. In the second part we will build the same with the Spring Framework. Source code: https://github.com/oivarc/j2ee-samples.git The source code you will find on the repository contains a bit more of what is showed here. There is also a simple page used for test that gives the possibility to add/edit the label in different languages. The code has been tested using NetBeans, Glassfish 4.1, JavaDB. It uses the EclipseLink for the JPA connection and PrimeFaces for the UI. Let's start introducing the database structure we will utilize to store the loca...
