Logging Overview

+ +

Overview

+ + + +

Using log while contributting for Tuscany DAS code

+
    +
  • While contributing to DAS code, please follow the following guidelines to add logging to your class +
    +Instantiate a logger +
    +- There is a logger factory available in org.apache.tuscany.das.rdb.util - To use it +
      +
    • private final Logger logger = LoggerFactory.INSTANCE.getLogger(MappingWrapper.class);
      • +
    +
    • +
+ + +

- To instrument your code with logging capabilities

+
    +
  • +
      +
    • if(this.logger.isDebugEnabled()) +
        +
      • this.logger.debug("your debug message");
        • +
      +
      • +
    +
    • +
+ + +

Note: As a performance enhancement, please surround your debug code with a check to see if debug is enabled or not.

+ +

Configuring DAS logging (log4j)

+
    +
  • Configuring with Tomcat +
    +There are two ways to configure log4j in Tomcat : +
      +
    • - Having a global log4j.properties inside %CATALINA_HOME%\common\classes +
      +- Having a global log4j.properties inside your own web app at WEB-INF\classes
      • +
    +
    • +
+ + +

Sample log4j.properties

+ +

# Set root logger level to DEBUG and its only appender to A1.

+ +

log4j.rootLogger=INFO, A1

+ +

# A1 is set to be a ConsoleAppender.

+ +

log4j.appender.A1=org.apache.log4j.ConsoleAppender

+ +

# A1 uses PatternLayout.

+ +

log4j.appender.A1.layout=org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern=[DAS RDB] - %c{1}.%M (%L) : %m %n

+ +

# Print only messages of level WARN or above in the package com.foo.

+ +

log4j.logger.org.apache.tuscany=OFF ** For further information, please follow the link : Tomcat FAQ - Logging
