This is a generator that comes with the Exist XML Database and lets you throw XQUERYs to an exist database (both local and remote).

I'm still working on it..

• The collection parameter throws an exception when using a remote database (xmldb:exist://host/....) due to the passing of serveral variables (session, request and response). Comment the throw line in RemoteXPathQueryService.declareVariable and compile to be able to connect to remote exist databases.
