Hello there!

I'm developing a webapp and I need to integrate Hibernate and Struts. I used the HibernatePlugin found in the Hibernate website, the struts config is ok (I've added the plugin configuration as mentioned in the website...). The hibernate.cfg.xml file is also ok. The problem is that when I try to load the webapp I get the log messages below.
I have all the jar files in place, in the lib folders of the webapp and of the appserver (Tomcat5).

What is the problem?? What can I do to solve it??

Thanks in advance,

Paulo Ferreira
