Hello,

I'm a new hibernate user. I want to exercise myself in Hibernate, so I'm trying to run the first Hibernate Application of the Hibernate Reference Documentation. But until now I'm not very succesful.

I'm using Eclipse 3.1M6, Hibernate3.0 and a mySQL database.

When I'm trying to run the Program I get the following message:


log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Initial SessionFactory failed: java.lang.NoClassDefFoundError: net/sf/ehcache/CacheException

I hope someone can give me a help. I don't know what I'm doing wrong.

Thanks,

Gaby

I think that could be because you don´t have a log4j.properties.
I had that error, well i had all errors to run my first application

good luck

well its seems you are missing ehcache from your classpath.

Many thanks!!!

It runs without any errors and warnings!

The error was the ehcache that I hadn't in my classpath.
The missing log4j.properties have caused the warning.


So, thanks a lot to both replies

Gaby
