Error - unable to log in to log4j

Question

I am trying to use log4j 1.2 jar in my hibernate 3.1 (in eclipse ) project example. Java code is fast, but the console shows me the following log4j warnings -

 log4j:ERROR Could not find value for key log4j.appender.stdout log4j.logger.org.hibernate.info log4j:ERROR Could not instantiate appender named "stdout log4j.logger.org.hibernate.info". 

I referred to the following -

• log4j-1.2.17.jar
• SLF4J-api-1.6.0.jar
• SLF4J-Simple 1.6.0.jar

The log4j.properties file contains -

 ### Direct log messages to stdout ### log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n ### set log levels - ### log4j.rootLogger=warn, stdout log4j.logger.org.hibernate.info ### log JDBC bind parameters ### log4j.logger.org.hibernate.type=debug ###log schema export/update ### log4j.logger.org.hibernate.tool.hbm2ddl=debug 

How to fix these warnings? I am new to registration and I need help. find it out.

Thanks.

This line:

 ### Set Log Levels - ### log4j.rootLogger=warn, stdout log4j.logger.org.hibernate=info 

Must be broken into two lines:

 log4j.rootLogger=warn, stdout log4j.logger.org.hibernate=info 

Wow! Like a newbie. I would never understand something like this.

The code I'm using is finally here -

 ### Direct log4j properties to STDOUT ### log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n ### Set Log Levels - ### log4j.rootLogger=warn, stdout log4j.logger.org.hibernate=info ### Log JDBC Bind Parameters ### log4j.logger.org.hibernate.type=debug ### Log schema/export update ### log4j.logger.org.hibernate.tool.hbm2ddl=debug
