Hi,

I got everything working except got an error when load the page with data populated. See errors below:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.orm.hibernate3.HibernateQueryException: EmployeeCourse is not mapped [From EmployeeCourse where employee = ?]; nested exception is org.hibernate.hql.ast.QuerySyntaxException: EmployeeCourse is not mapped [From EmployeeCourse where employee = ?]
.....
Root cause
org.springframework.orm.hibernate3.HibernateQueryException: EmployeeCourse is not mapped [From EmployeeCourse where employee = ?]; nested exception is org.hibernate.hql.ast.QuerySyntaxException: EmployeeCourse is not mapped [From EmployeeCourse where employee = ?]
org.springframework.orm.hibernate3.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:660)

I used annotation conversion from Legacy code to Annotation. I've checked everything in the configuration xml files, and all DOMAIN OBJECT everything looks fine. However, I think there is something wrong or missing that caused an exception above.

Does anyone has any clue or ran into this problem?

Your input is greatly appreciated!

HC

Below is a complete page of errors. Does anyone has any clue about these errors and how to correct it ? I think something missing or didn't configure right ?
