Configuring SLF4J

[Songezo Nkukwana]

Hi, i have a Hibernate Java Application Tester which i use slf4j for my console output .... The loggers work fine but only display info within the application class. I have other classes on different packages using the same slf4j logger, but none of those are displayed ... My log4j.properties is placed under the src directory ... All my classes are situated on their respective packages and use slf4j, but only the class with main() method gets logged/display ... Any reason for that?

here's my log4j.properties

log4j.rootLogger=INFO, hAppender, stdout

# File Appenders 
log4j.appender.hAppender=org.apache.log4j.RollingFileAppender
log4j.appender.hAppender.File=hiberTest.log
log4j.appender.hAppender.MaxFileSize=600KB

# Keep 1 backup file 
log4j.appender.hAppender.MaxBackupIndex=3

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

# Console Appenders 
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 [%t] %c{1}:%L - %m%n

my application class

package hibernate.apptest;

import hibernate.model.Member;
import hibernate.service.MemQualServiceImpl;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import sitawc.generic.persistence.HibernateUtil;

public class HiberTester {

	/**
	 * slf4j logger
	 */
	final static Logger slf4j = LoggerFactory.getLogger(HiberTester.class);
	Session currentSession  = null;

	public static void main(String[] args) {
		HiberTester test = new HiberTester();
		test.init(); 
	}

	protected Session getSession() {
		currentSession = 
			HibernateUtil.getSessionFactory().getCurrentSession();

		if( currentSession == null ) { 
			slf4j.info("Opening a new session... session was null");
			return HibernateUtil.getSessionFactory().openSession();
		}
		else
			return currentSession;
	}

	public void init() { 

		try { 						
			
			/*  * Begin a transaction demarcation 
			 */
			Transaction tx = getSession().beginTransaction();
			
			MemQualServiceImpl memServ = new MemQualServiceImpl ();
			
			Member m = new Member("66102015");		
			List<Member> results = memServ.searchCriteria(m);
				
			for(Member obj: results) {
				slf4j.info ("Force No: " + obj.getForce());
				slf4j.info ("Name: " + obj.getFullName());
				slf4j.info ("Gender: " + obj.getGender());
				slf4j.info ("Application Code: " + obj.getAppCode());
				slf4j.info ("Rank Code: " + obj.getRankCode());
			}
			
			tx.commit();
			
		} 
		catch (Exception e) {
			slf4j.info("---- Exception occurred : " + e.getClass().getName() + " : " + e.getMessage()); 
			e.printStackTrace();
		}	
	}
}						

other classes not displayed ...

public class MemberDAOImpl 
	extends GenericHibernateDAO<Member, String> 
	implements MemberDAO {
	
	final static Logger slf4j = LoggerFactory.getLogger(MemberDAOImpl.class);
	
	// property constants	
	public static final String RANK_CDE = "rankCode";

	@SuppressWarnings("unchecked")
	public List<Member> findByProperty(String propertyName, Object value) {
		slf4j.info("finding Member instance with property: " + propertyName
				+ ", value: " + value);
		try {
			String queryString = "from Member as model where model."
					+ propertyName + "= ?";
			Query queryObject = getSession().createQuery(queryString);
			queryObject.setParameter(0, value);
			return queryObject.list();
		} catch (RuntimeException re) {
			slf4j.error("find by property name failed", re);
			throw re;
		}
	}
}

finding Member instance with property: does not get displayed
