Dan Allen commented on JBSEAM-1923:

Please note that this issue has now resolved JBSEAM-1537, which is basically a duplicate of this issue.

Specifying the hibernate dialect in the persistence.xml file is useful when:

a. There is more than one dialect available for a database, and you want to specify which one to use (such as MySQL)
b. Hibernate does not automatically detect the dialect, even though the dialect exists in the Hibernate library (such as H2)
c. You provide your own dialect for a database and want to use it as an overridden

Therefore, it makes sense to include it, even if in most cases it is redundant.

> seam-gen does not generate a "hibernate.dialect" propery in persistence.xml, although the hibernate.dialect property is collected and saved in hibernate-console.properties. Therefore some hibernate mappings and generated code can be incorrect.
