JMapper use in Payara 4.1

[Elmosen]

Hello,

I use a simple mapping from one type to another, and everything works fine in my JUnit test. I have two classes with three identical fields of type Integer, String, and Date.

When I try to use my mapping within an EJB for a Webservice, deployed on a Payara 4.1 server, I get an Exception - stack trace and other things see below in this message.

Is it a known problem or are there any hints for me regarding missing configuration?

Thank you in advance, regards Marc

And here the code snippet of the usage of the JMapper which already stops at the JMapper constructor:

   public List<ReportCategoryDTO> getAllReportCategories() {
        JMapper<ReportCategoryDTO,ReportCategory> myMapper = new JMapper<>(ReportCategoryDTO.class, ReportCategory.class);
        List<ReportCategoryDTO> result = new ArrayList<>();
        for (ReportCategory eachEntity : (List<ReportCategory>)em.createNamedQuery("ReportCategory.findAll").getResultList()) {
            result.add(myMapper.getDestination(eachEntity));
        }
        return result;
    }

Hi @Elmosen,

It is probably a class loading problem, can you share a runnable project?

Hello Avurro,

thank you four your fast reply. I was sick since friday, so I was not able to answer sooner.

Yes, I'm sure it is a class loading problem. Did you hear about any Payara or Glassfish problems before?

I will now start with Dozer for my mapping (I used it already earlier), but I hope I will find the time to strip my project to give it to you for further investigation.
