Hello,
I'm currently using GWT 2.0.4 with Hibernate3, on Eclipse Helios, to
create a simple web application. So far, I'm able to reach the
database and do some RPC's to the server perfectly without any
problem.
The problem arises whenever I try to test out my server classes (the
data access objects) with a JUnit test case. I've added the JUnit.jar
(JUnit 3) and modified the "Run As..." properties to include the /src
and /test folders in the classpath. Whenever I call my class methods I
get the following exception:
Initial SessionFactory creation failed.java.lang.NoClassDefFoundError:

Caused by: java.lang.ClassNotFoundException:
org.slf4j.impl.StaticLoggerBinder
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
The HibernateUtil.java code is:
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new
Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." +
ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
>From what I understand, the problem lies on the fact that I haven't
added the sl4j.jar to the test server. Is the any way to do that?
Thanks in advance!
