WebSphere stdout/stderr logging redirect

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.LevelRangeFilter
log4j.appender.stdout.filter.filter1.levelMin=DEBUG
log4j.appender.stdout.filter.filter1.levelMax=INFO

log4j.appender.stderr=org.apache.log4j.ConsoleAppender
log4j.appender.stderr.Threshold=WARN
log4j.appender.stderr.Target=System.err

log4j.appender.stderr.layout.ConversionPattern=[%-5p] %t (%d{dd/MM/yy HH:mm:ss}) %c{1} - %m\n

JSF2 View Scope with Spring Core

Working with Spring and JSF2 I encountered the need to use something like a ViewScope bean. The Spring Framework support the following scopes bean scopes : singleton prototype request session globalSession Adding a new scope is quite simple using Spring. To add the View Scope in the Spring IoC container it is necessary to create a custom scope which implements the org.springframework.beans.factory.config.Scope interface and register it with the Spring Custom Scope Configurer. ViewScope implementation package eu.ac.tutorial.spring.scope; import java.util.Map; import javax.faces.context.FacesContext; import org.springframework.beans.factory.ObjectFactory; import org.springframework.beans.factory.config.Scope; public class ViewScope implements Scope {     @Override     public Object get(String name, ObjectFactory<?> objectFactory) {         if (FacesContext.getCurrentInstance().getViewRoot() != null) { ...

Spring Data Repositories: Query by Specification

Working with Spring and Spring Data repositories I got the need to have flexible queries based on some of the property of an entity class that should be put in OR in the query if they were present. Instead of creating a query for each combination of properties, I used one of the facilities provided by Spring-Data: the query by Specification. Before going into the details some background information. What I am going to show is an example based on the JpaRepository using Hibernate as persistency layer. A full working example can be found here:  query-by-spec The trick is in the use of the Specification interface in combination with a JpaSpecificationExecutor. Let's start... First we define an entity with some properties: @Entity @Table(name = "person") public class Person { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @Column(name = "name") private String name; @Column(name = "surname") private Strin...
