I’m developing new web app with Struts2 framework, eclipse, and I’ve mapped the db structure with Hibernate. The problem is that when I execute my “list” action the framework returns me this error: 


    Struts Problem Report

    Struts has detected an unhandled exception:

    Messages:

The server.xml is:

                </Context>
            </Host>
        </Engine>
    </Service>
</Server>

I’ve also hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>

                </Context>
            </Host>
        </Engine>
    </Service>
</Server>

Any suggestion where I can look? I’m really going crazy!

    I found the solution, and the real problem. I edit the server.xml in Eclipse, and I didn’t watch the real publish result. For strange reason eclipse remove the resource link in the real server.xml, but show me the link in eclipse view. So i gooogled all day long and I find that I must add in the context.xml file under WEB-INF directory this: 

    <?xml version="1.0" encoding="UTF-8"?> 
<Context antiJARLocking="true" path="">
<ResourceLink global="jdbc/main" name="jdbc/main" type="javax.sql.DataSource" /> 
</Context>
