After deployment to tomcat: entity class not found

[itay sahar <it...@gmail.com>]

Hello,

I've successfully created all hbm,POJO and DAO files using Hibernate tool
which is great!!!

Once deploy to Tomcat I got the exception:
nested exception is org.hibernate.MappingException: entity class not found:
MyClass

the full stack is:
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'sessionFactory' defined in ServletContext resource
[/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested
exception is org.hibernate.MappingException: entity class not found: MyClass
