1) as a test project I use dvdstore;
2) dvdstore-ejb - I change hibernate-console.properties to use MySQL instead of HQL db for dvdstore-ejb Hibernate Console Configuration:
#hibernate.connection.password=
#hibernate.connection.username=sa
#hibernate.connection.driver_class=org.hsqldb.jdbcDriver
#hibernate.dialect=org.hibernate.dialect.HSQLDialect
#hibernate.connection.url=jdbc:hsqldb:MyDB
hibernate.connection.password=p@ssw0rd
hibernate.connection.username=root
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.connection.url=jdbc:mysql://localhost:3306/jpa3
3) I generate Hibernate db for MySQL via dvdstore-ejb Hibernate Console Config -> context menu -> Run Schema export;
4) then I run Seam Generate Entities for dvdstore project - the entities was generated succesfully;
5) rebuild dvdstore-ejb Hibernate Console Config - get exception - with duplicate Inventory - ok that is right;
6) so I delete generated entities;
7) during 15 minutes my rbds decelerate - it works, but very slowly; no exceptions;
8) then I get situation - screenshort-2 - it start to work normally;
