Spring,J2EE and some random thoughts

Logging using Spring Framework

2008-09-04T16:48:00.000-07:00

Step 1:

It is simple. Just add log4j dependencies in maven pom.xml.

If you are using common logging, add following dependency

<groupId>commons-logging <groupId>

<artifactId>commons-logging<artifactId>

Step 2 :

Create a log4j.properties or xml as per your requirement.

Here is sample log4j.properties

# following line defines the log level and mode of outputs. Console and rolling file

log4j.rootLogger= INFO, CONSOLE, ROLLING

log4j.logger.com= INFO, CONSOLE, ROLLING, DAILY

# Print only messages of level WARN or above in the package org.apache.

log4j.logger.org.apache=WARN

# Print only messages of level WARN or above in the package org.springframework.

log4j.logger.org.springframework=WARN

# CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender

log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout

log4j.appender.CONSOLE.layout.ConversionPattern=%d %-5p [YOURPROJECTNAME] [%t] %C{2} (%F:%L) - %m%n

# ROLLING

log4j.appender.ROLLING=org.apache.log4j.RollingFileAppender

log4j.appender.ROLLING.File=yourprojectname.log

log4j.appender.ROLLING.layout=org.apache.log4j.PatternLayout

log4j.appender.ROLLING.layout.ConversionPattern=%d %-5p [YOURPROJECTNAME] [%t] %C{2} (%F:%L) - %m%n

log4j.appender.ROLLING.MaxFileSize=10MB

log4j.appender.ROLLING.MaxBackupIndex=5

# DAILY

log4j.appender.DAILY=org.apache.log4j.DailyRollingFileAppender

log4j.appender.DAILY.layout=org.apache.log4j.PatternLayout

log4j.appender.DAILY.layout.ConversionPattern=%d %-5p [YOURPROJECTNAME] [%t] %C{2} (%F:%L) - %m%n

log4j.appender.DAILY.File=yourprojectnamedaily.log

log4j.appender.DAILY.DatePattern=yyyy-MM-dd

Step 3.

Add following line in application-context.xml

<list>

<value>classpath:log4j.properties<value>

<list>

<bean>

That’s it. You are done!!!

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

Change Log level without re-starting server –

If it is required that you have to change log level frequently, it would be

frustrating to restart the server every time. To avoid restarting application

server whenever you modify log4j.properties file.

Simply add one line of configuration in application-context.xml that is –

<value type="long">enter time here<value>

*Time is in millisecond.

So the configuration will look like as follows.

<list>

<value>classpath:log4j.properties<value>

<list>

<bean>

But you should not use above configuration in production server. Please visit the

following link for more information

Code Assistance Tip:

Here are one useful tip if you are using Eclipse

1.1. Go to window->Perspective->Java->Editor->Templates

1.2. Create new.

1.3. Give following parameters.

Name – yourprojectnameLog

Description - it will create a logger instance for enclosing class of the project.

Pattern :

If you are using common logging then use

private static final Log logger=LogFactory.getLog(${primary_type_name}.class);

If you are using log4j then use

private static final Logger logger=Logger.getLogger(${enclosing_type}.class.getName());

To use it in java classes, simply press ‘yourproje’ and click ctrl+space and select

yourprojectnameLog.

Hello India : Some eye opener american way of living

2008-05-29T13:59:00.000-07:00

Whenever I go back to India I feel there are so many misconceptions about USA. Here I am not going to praise USA but I felt that it is my moral duty to inform the readers of India about some very facts of this country.

1. Eighty percent of Americans wake up before 5 AM. They believe in early to bed and early to rise. Back in India every parents tell their children about this ages old mantra of good health. They don't listen.

2. Here government offices timings are 8.00-5.00. The senior officers come early in office then their employees. (Think about any government office in India). Why they are wasting your tax money?

3. Every officer here put their heart/at least show to help you with your issues and problems.

4. You don't need to give bribe to get your work done. No here also government employees get less pay then private companies employees.

5. Almost all Americans are really patriotic. I met a person here who used to visit India to get army secrets during 80s and his statement was shocking. He told me that he used to get any secrets from soldiers by paying money. He consider that it was a cake-walk. Well that was in 80s. Presently I have seen that many Indians who come here for work they simply speak about negative points of India to Americans and feel that they are becoming more friendly to Americans. In fact American don't respect such people make fun of it at their back.

6. Boys have to live separately as soon as they become 18 years and earn their own money and study. I have seen guys even above 30 years of age dependent on their parents in India.

7. Americans are very shy and conservative. They don't drink everyday as European do. In Europe it consider as a social drinking if every evening they go to local pub for few drinks after work. In America it is consider as an alcoholic.

8. Americans don't litter. They don't throw garbage on side of the road, And if they see that they pick it and throw it in trash can.

9. Here there is no concept of page three. Nudity in TV and newspaper is just out of imagination just opposite to page three of UK. Metro girls are dying in India to come on page three.

10. Americans pay their taxes.

11. Here there is respect for each other. Americans don't stare at opposite sex whereas in India so called love starts by staring each other from their balcony. Come on. Respect women.

12. There are so many volunteer in Fire department and police department. If there is news of missing person, there would be more than 500 volunteer searches the nearby areas day- and night.

13. American donate generously part of their money regularly or at least once in their lifetime.

There are so many more to come....
