Subject: returning a node (I can't find a
solution anywhere!)
I know this may be a basic question, but I've
tried every possible option I can think of. Simply put, all I'm trying to do,
is add a "toXML()" method to a class, which converts my data into an Element
which is returned to the calling object:
public class headache{
public Element
toXML(){
.....
return
Element;
}
}
DocumentImpl doc = new
DocumentImpl();
Element root =
doc.createElement("root");
headache h = new
headache();
Element e =
headache.toXML();
root.appendChild(e);
Running this code I get:
Context log: path=""
Error in qResults service() :
org/w3c/dom/DOMException
java.lang.InstantiationError:
org/w3c/dom/DOMException
(Mind you, there is no such thing as a
java.lang.InstantiationError, but there is a
java.lang.InstantiationException)
I've tried setting up a cloneNode(node,true) at
the "headache" class side as well as on the calling class side:
public class
headache{
public Node toXML(){
.....
return Element.cloneNode(true);
}
}
DocumentImpl doc = new
DocumentImpl();
Element root =
doc.createElement("root");
headache h = new
headache();
Element e =
headache.toXML();
root.appendChild(e);
This returns the same. If I try to use importNode(node,true) on the
calling class side:
rott.appendChild(doc.importNode(headache.toXML(),true));
I get:
Context log: path="" Error in qResults service() :
null
java.lang.NoSuchMethodError
at
org.apache.xerces.dom.DocumentImpl.importNode(DocumentImpl.java:888)
I'm using Xerces 1.4.0 and JDK1.3. The code is running in
servlets.
Cheers,
Anthony
