My project is a tomcat project,I m creating war files through eclipse to deploy in server.
The versions used in my project are
Hibernate verion 3.1.3
JDk version 1.5
Tomcat version 5.5
The application works fine in my local Pc,Windows server,and some Linux server.

In some Linux server the application which resides in tomcat didn't starts .

In tomcat's log file that is catelina.out it's only giving that
" ERROR LISTENER START."
But when i am looking the log file that my application is doing at the time of starting tomcat.

After successfully mapping some db table columns with my hibernate.hbm.xml files it through exception like this

I don't think there is any problem in source code or in data base.
The same code and DB script is used in both Windows and Linux server.

If some one can figure out my problem that will be very helpfull to me.

Waiting for an early response

Thanks in Advance
