ERROR: HHH000299: Could not complete schema update java.lang.NullPointerException

Question

I have a web application in the following environment.

• JPA 2.0
• Spring 3.2.2
• MySQL 5.6.11
• Hibernate 4.2.0 CR1
• Apache Tomca

Answer 1

It looks like you're incorrectly mixing Hibernate dialects and databases. In your original issue you have a MySQL database and a dialect of org.hibernate.dialect.HSQLDialect (see first code block below).

In your solution you have the MySQL database and the correct dialect of org.hibernate.dialect.MySQL5Dialect (see second code block below).

If you had changed the databasePlatform in the original to be the MySQL dialect it would have worked as well.
