UTF - 8 with JPA and Glassfish 4.0

Question

I am having difficulties with UTF-8 characters. This is a simple JSF project. I use JSF 2.2 and Glassfish 4.0

I have a method where I go:

em.persist(         


        

Answer 1

When using Glassfish, you can set these properties as additional to your JDBC Connection Pools. Locate and view your database connection in Web Administration (Resources->JDBC Connection Pools->your.connection). In additional properties tab add (if there are not present yet) mentioned properties and restart your server:

//name, value
characterEncoding, UTF-8
characterSetResults, UTF-8
useUnicode, true

The result will be the same if parameters are added to URL, but this is more maintainable solution in my opinion.

Answer 2

This solved it:

jdbc:mysql://localhost:3306/fus?useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8

so this was wrong:

jdbc:mysql://localhost:3306/fus?useUnicode=true&connectionCollation=utf8_general_ci&characterSetResults=utf8
