root/greenstone3/trunk/resources/java/SOAPServer.java.in @ 16756

Revision 16756, 3.6 KB (checked in by ak19, 11 years ago)

Since greenstone3 core ModuleInterface?.process() now takes a Node and RETURNS a Node, have copied the XMLConverter.nodeToElement() into here to convert the Node back into the Element version of the response.
