The class 'javax.persistence.Convert' is required to be in the selected libraries

Question

When selecting a user library as the JPA implementation in Eclipse Dali's project settings, the following error message is displayed:

The class 'javax.persistence.Convert' is required to be in the selected libraries

But the class javax.persistence.Convert is correctly included in the classpath of my user library, so how can this problem be resolved?

Answer 1

Download Eclipse Link 2.X.Y (Version 3.x.y seems to have different libs)

From the Download use the libraries / jars

• eclipselink/jlib/eclipselink.jar
• eclipselink/jlib/jpa/jakarta.persistence_X.Y.Z.jar

And place them into your user Library by either

• The "Manage Libraries ..." Button on the very right of your screenshot
  or
• Eclipse -> Windows -> Preference -> Java -> Build Path -> UserLibraries
