org.hibernate.query.sqm.UnknownEntityException: Error upgrading CAS server from 6.6.x to 7.0.x

[Roberto Crespo]

Hi everebody!

We are upgrading CAS to 7.0.3 with Java21, Spring 6.1.2 and Hibernate 6.4.4.Final. We have made required changes in dependencies (e. g. javax to jakarta) and we have build and deploy the application in tomcat. The problem is in execution time, when we make a query with JPA, the entities are not recognized. 

When we inspect entityManager.getMetamodel().getEntities() the value is '[]', however the value in 6.6.6 version is the list of entities (defined with @Entity annotation)

what could be the problem?

thanks in advance!!
