解决方案

您需要检查冲突类路径中org.apache.log4j.Level的版本并解决它。 TRACE级别在1.2.12或更高版本的log4j jar中可用。

I am developing a project which accesses the database but im having some problems. I try to use hibernate 3.2 and 4.52 but it doesn't work.

log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.

    at aucas.Aucas.main(Aucas.java:45)

the exception is in this lines of code

public Aucas() {
    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Session session = sessionFactory.openSession();
    LoginDialog d = new LoginDialog(null,false,this);
}

解决方案

You need to check for conflicting version of class org.apache.log4j.Level in your classpath and resolve it. The TRACE level is available in the log4j jar of version 1.2.12 or higher.
