How to configure log4j in Jdev 11g

Ever wanted to use log4j in your ADF project? Well though Oracle doesn ' t recommends the use of log4j, I say its purely your choice to use it or not.

So how does we configure log4j in ADF? Pretty simple. Just follow these steps

1) Add log4j jars in the project library

2) Create a file log4j.properties in your application Sources Directory (this folder was seen in Jdev–in both Viewcontrol Ler and Model Folder).

The For model project is the present at <path of model PROJECT>MODEL\SRC.

For Viewcontroller Project This file have to be present as <path of model PROJECT>VIEWCONTROLLER\SRC

3) Paste The following contents

****************************

# Set Root logger level to INFO and it only appender to ConsoleOut.
Log4j.rootlogger=info,consoleout,f
# consoleout is set to be a consoleappender.
Log4j.appender.consoleout=org.apache.log4j.consoleappender
# ConsoleOut uses Patternlayout.
Log4j.appender.consoleout.layout=org.apache.log4j.patternlayout
log4j.appender.consoleout.layout.conversionpattern=%-5p: [%d]%c{1}–%m%n
Log4j. Logger.org.apache.jsp=debug
Log4j.appender.f=org.apache.log4j.fileappender
Log4j.appender.f.file=c:/logs/logger.log
Log4j.appender.f.layout=org.apache.log4j.patternlayout
log4j.appender.f.layout.conversionpattern=%d{[ EMAIL&NBSP;PROTECTED]:MM:SS,SSS}%-5p (%13f:%l)%3x–%m%n

1. Add the log4j jars to the project.

2. Create a new log4j.properties and place it into the MyClasses directory and add the following to it
