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 crash. 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..........

In what way do you run more than one application? I mean haw do you run more than one tomcat instance and what exception have you?

I have few web applications and define different host for each application in web.xml..........
If there are only one application using hibernate, no matter how many hosts that I put in web.xml, everything still work fine............. but if there are more than one application using hibernate and when I run some function that need to use database through hibernate, the program will crash without any exception and error message........I think it's because the tomcat crash...........
I need to terminate tomcat, remove and leave only one appliation using hibernate in web.xml.

Therefore when I have two applications that use hibernate, I have to modify hosts in web.xml and restart tomcat to switch between those applications.

so is there anyone know why????
