Are there any exceptions in the Eclipse log file?– Message Body ——————————-
I went thru the hibernate demo help but when I finished and ran the HibernateReadTest.java as it suggested I got errors. I am assuming the instructions left something out. Here is the message stream I got:
log4j:WARN No appenders could be found for logger (com.genuitec.hibernate.EchoMessageDAO).
log4j:WARN Please initialize the log4j system properly.
