Hi All, Here is the requirement. The users will load xml document1 on left hand side text area and document2 on right hand side text area. Then they should be able to map the fields from document1 to fields of document2 by doing drag and drop lines. Also this mapping needs to be persisted so that if they open the map later on,it will display the graphical view of the mapping which was already done. Is there any applet that can fulfil this requirement? Other suggestions are welcomed.
