New Toplink JPA release?

Question

In another thread a fix was made to the Toplink JPA codebase.
Toplink comes to a halt in the merge
The question is how to get to the fix. The latest build on the website is 2b41 from March 2007! I cannot find a source access.
How to get the latest Toplink JPA implementation?

Answer 1

There are no converter related enhancements for TopLink Essentials. If you want advanced support in this area you'll need to move to either Oracle TopLink or EclipseLink. It's pretty easy to do.
In TopLink Essentials you have the option to customize a basic mapping with your own converter. You declare the customizer in the persistence.xml, e.g.:
<property name="toplink.descriptor.customizer.Book "value="example.toplink.BookCustomizer"/>And in your customizer you can plug in a Converter, e.g.:
public class BookCustomizer implements DescriptorCustomizer {
    public void customize(ClassDescriptor descriptor) throws Exception {
        DirectToFieldMapping categoryMapping = (DirectToFieldMapping)
                  descriptor.getMappingForAttributeName("category");
        categoryMapping.setConverter(new BookCategoryConverter());
    }The converter you set on the DirectToFieldMapping (i.e., Basic) has to implement oracle.toplink.essentials.mappings.converters.Converter. In the converter you can do pretty much whatever you like including Integer/Boolean conversion.
