Yes, Dali provides a UI for EclipseLink which provides library management and easier configuration of EclipseLink extensions.
Using Dali 3.2 on Helios isn't a supported configuration, but if you wanted to try it out, the easiest way to do it would probably be to use the WTP update site and try to update your Dali software that comes in Helios to 3.2. This would end up updating much of WTP to 3.4. In fact it would probably best to update all of WTP to 3.4 in the process. This configuration would possibly work on a Helios base, but it is untested and may result in obvious and/or hard to diagnose problems.
