Thanks, I'll apply it, too.

Sure it does. Thanks a lot.
Btw, when I get the resources list I would like to add it to a document.
This will be a document fragment, the method should return a DOM Node and
this one will be after that added to the root element I already created. I'm
trying the usual iterating through the ResourceSet and creating the fragment
in the method, but it is giving me an eception, something like 'DOM005 Wrong
document'. I do not know what's happening, any ideas? (code attached below).
Thanks a lot :-)
----------------
/**
* Search for documents in the DB. If not found, return null.
* The rootCollection is initialized in the constructor
* I'm trying to return the fragment in xmldoc but it gives the exception
:-(
*/
public Node find(String subCol, String xpath) throws Exception {
Collection col = null;
Node xmldoc = null;
try {
Class c = Class.forName(driver);
Database database = (Database) c.newInstance();
DatabaseManager.registerDatabase(database);
String localCol = rootCollection + subCol;
col = DatabaseManager.getCollection(localCol);
XPathQueryService service =
(XPathQueryService) col.getService("XPathQueryService", "1.0");
ResourceSet resultSet = service.query(xpath);
ResourceIterator results = resultSet.getIterator();
while (results.hasMoreResources()) {
Resource res = results.nextResource();
System.out.println((((XMLResource)res).getContentAsDOM().getFirstChild()));
if(xmldoc!=null) {
Node childNode = ((XMLResource)res).getContentAsDOM().getFirstChild();
xmldoc.appendChild(childNode);
}
else {
xmldoc = ((XMLResource)res).getContentAsDOM().getFirstChild();
}
}
return (xmldoc);
}
catch (XMLDBException e) {
System.err.println("XML:DB - Find Exception occured " + e.errorCode);
throw e;
}
finally {
if (col != null) {
col.close();
}
}
}
I'd like to invoke this method from this one:
/**
* Inititializes a DOM Node to list the available Equipment types
*
*/
public void initEquipmentTypes() {
DOMImplementation impl;
try {
// Find the implementation
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
factory.setValidating ( false );
DocumentBuilder builder = factory.newDocumentBuilder();
impl = builder.getDOMImplementation();
}
catch (Exception ex) {
throw new RuntimeException("Failed to initialize DOM factory. Root cause:
\n" + ex);
}
//Create the node for the root, 'Class'
Document doc = impl.createDocument( null, "EquipmentTypes", null);
equipmentTypes = doc.getDocumentElement();
//find the Equipment Types available in the database
String localSubCol = "/Recording/Equipment/EquipmentType";
try {
//Here is where I create an instance and call the method above
//result is not null but it gives an exception
XindiceManager xi = new XindiceManager();
Node result = xi.find(localSubCol, "//EquipmentType");
if (result!=null) {
equipmentTypes.appendChild(result);
}
}
catch (Exception e) {
System.err.println("Cannot get results from the DB: " + e.getMessage());
}
}
