Hi guys,

Since last monday, I’m facing problems to connect with the entitymanager. The programs was generated with MyEclipse JPA, however I’m getting this message at console

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
log4j:WARN Please initialize the log4j system properly.[/b]

How can I fix it ?
Thanks in advance

And the entity manager

package br.gov.sp.polmil.scsu.persistence;

import java.util.logging.Level;
import java.util.logging.Logger;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.persistence.Query;
/**
 * @author MyEclipse Persistence Tools
 */
public class EntityManagerHelper {
    
    private static final EntityManagerFactory emf; 
    private static final ThreadLocal<EntityManager> threadLocal;
    private static final Logger logger;
    
    static {
        emf = Persistence.createEntityManagerFactory("SCSUPU");         
        threadLocal = new ThreadLocal<EntityManager>();
        logger = Logger.getLogger("SCSUPU");
        logger.setLevel(Level.ALL);
    }
        
    public static EntityManager getEntityManager() {
        EntityManager manager = threadLocal.get();        
        if (manager == null || !manager.isOpen()) {
            manager = emf.createEntityManager();
            threadLocal.set(manager);
        }
        return manager;
    }
    
     public static void closeEntityManager() {
        EntityManager em = threadLocal.get();
        threadLocal.set(null);
        if (em != null) em.close();
    }
    
    public static void beginTransaction() {
        getEntityManager().getTransaction().begin();
    }
    
    public static void commit() {
        getEntityManager().getTransaction().commit();
    }  
    
    public static void rollback() {
        getEntityManager().getTransaction().rollback();
    } 
    
    public static Query createQuery(String query) {
        return getEntityManager().createQuery(query);
    }
    
    public static void log(String info, Level level, Throwable ex) {
        logger.log(level, info, ex);
    }
    
}

Thanks again

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
log4j:WARN Please initialize the log4j system properly.[/b]

You have not initialised log4j properly. Try reading the online log4j manual or by adding a log4j.properties file to your classpath (to a directory which is on the classpath to be precise).
http://logging.apache.org/log4j/1.2/manual.html

[Klaus Villaca]

Thank you. I’ll do that now

[Loyal Water]

Your welcome..

[frankc01a]

Just put a log4j.properties file in your class path, here is one:
#for debugging log4j itself
log4j.debug=false

#Logger-Priorities:
#DEBUG lowest, prints all messages
#INFO prints all messages with FATAL, ERROR, WARN or INFO priority
#WARN prints all messages with FATAL, ERROR or WARN priority
#ERROR prints all messages with FATAL or ERROR priority
#FATAL highest, prints only FATAL messages

# root logger
log4j.rootLogger=INFO, A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d{MMM d, yyyy h:mm:s a} %-5p %c{1} – %m%n

# Hibernate logging

#log4j.logger.org.hibernate=DEBUG
#log4j.logger.org.hibernate=INFO
log4j.logger.org.hibernate=WARN
#log4j.logger.org.hibernate=ERROR
#log4j.logger.org.hibernate=FATAL
