struts, hibernate, mysql problem

I am using eclipse, struts, hibernate, mysql, tomcat to run my web application. When I try to run more than one application that using hibernate, then all the application will hang. I am only able to run one application at a time and keep changing the host in server.xml if I want to run other application that use hibernate.

This problem occur only when I run more than one application that using hibernate. So is anyone know why does this happen? help plx..........
