Hello we have a web application where we use the Spring framework together with Hibernate and ehcache. The web application works fine. Howeve we want to deploy the same application under a different web app name. The reason for doing so is to have one application access the db and the other one access an old database and let the user search for older records.
These two webapps do not share any mapping files, classes or XML files. They are two separate and distinct web applications (at least I think so).
The problem we encounter is that when both applications are running we get an
Code:

The point where one of the classes we have written is referenced, points to this line of Java code (GesDdbAdminServicesDAOHibernate.java:99):
return getHibernateTemplate().find("from User user where user.login = ?", loginName);
Note that the above line should return a List of "User" objects but the error message complains about "Unit" objects (a "User" contains a "Unit").
Not sure what is going on. I did a search but I couldn't find any information. Any help is appreciated.
Thank you.
Our Hibernate version is 2, we use WebLogic Server 8.1 under Linux RedHat 9, MSSQL Server 2000 and the mapping documents follow:
