Hello again,
So far so good, but i still have a problem. In the manual there is a referense to a configuration file, objectRendering.xml in chapter3 but its not there! I dont know the structure of how its ment to be implementet. I have a configuration file as listet here:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<!-- THIS IS THE WORKSTATION LOG4J CONFIGURATION FILE -->
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> <!-- Denne Appender benyttes fra og med DEBUG level og opefter --> <param name="Threshold" value="DEBUG"/> <param name="Target" value="System.out"/> <layout class="dk.jyskebank.j2ee.core.dump.DumpLayout"> <param name="ConversionPattern" value="%d %-5p [%t] %C{2} (%l) - %m\n" /> </layout> </appender>
<root> <priority value="debug"></priority> <appender-ref ref="CONSOLE"/> </root> </log4j:configuration>
I would like to be able to construct a render for my loggable objects but as im trying to explain i wery bad english, i dont know how and there. Can you help me?
Best regards - Søren

Hi, ObjectRenderers do not replace a Layout. They are classes that know how to render objects of a specific class. For example:
class A { private int a; public int getA() { return a; }
private int b; public int getB() { return b; } }
public class ARenderer implements ObjectRenderer { public String doRender(Object o) { if(o == null) { return null; } else if {! (o instanceof A)) { return null; } else { A obj = (A) o; return "Sum = " + (obj.getA() + obj.getB()); } }
They are specified in a properties configuration file as follows: log4j.renderer.A = ARenderer
