JPA from EclipseLink to which provider?

Question

Hallo all. I'm using EclipseLink as JPA provider in our project. As described here we have e big problem with char trimming with a DB char column with EclipseLink

I tried the way to remove the jdbc bind parameter but I cannot make this change for production environment: I tried to write my own SessionCustomizer but it doesn't seem to work.

public class ContrattoSessionCustomizer implements SessionCustomizer {

    /**
     * @see org.eclipse.persistence.config.SessionCustomizer#customize(org.eclipse.persistence.sessions.Session)
     */
    @Override
    public void customize(Session session) throws Exception {
        System.out.println("hello.....");
        DatabaseLogin login = (DatabaseLogin)session.getDatasourceLogin();
        login.setShouldTrimStrings(false);

    }

}

I would like to migrate from EclipseLink to another JPA provider; yesterday I tried with hibernate but unfortunately to migrate to this provider I need to change my domain model, since it seems that hibernate does not support some mapping definition that I used with eclipse link.

Is there another good provider to test without make changes to my domain model mapping?

Kind regards Massimo

Can't see how changing providers will help you, as it is a database issue. You seemed to state that you solved the issue by disabling parameter binding? Are you registering your SessionCustomizer in your persistence.xml?
