Hi, First, Gilead does not support yet TopLink or EclipseLink (only Hibernate is supported), even if issues are the same (have a look at http://noon.gilead.free.fr/gilead/index.php?page=presentation for an explanation about JPA/GWT integration issues).
If TopLink is not mandatory, you can "easily" switch to Hibernate (that's JPA power) and use Gilead to solve your issue. As far as I know, Dreamsource is not JPA compliant, so using it instead of your JPA code could be very expensive if you have a lot of domain classes... Sorry, no "magic" solution... Hope this helps !
