Subject [jira] Resolved: (JCR-1952) DOMException: NAMESPACE_ERR thrown when exporting document view
Date Sun, 22 Feb 2009 00:34:01 GMT

     [ https://issues.apache.org/jira/browse/JCR-1952?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jukka Zitting resolved JCR-1952.
--------------------------------

    Resolution: Fixed

I resolved this by replacing the JAXP serialization code with a custom XML serializer over
whose behaviour we have full control. The custom serializer and related classes were added
in revision 746602 and in revision 746603 I modified the JCR XML exports to use this new serializer.

Note that to keep things simple the new serializer is designed to only work with a fairly
constrained stream of SAX events. This is OK for the XML exports we generate, but not necessarily
for things like the DOM to SAX conversions used by the webdav component. Thus I've only modified
the JCR XML exports to use the new serializer and kept other XML serializations based on the
existing SerializingContentHandler class. 

Merged to the 1.5 branch in revision 746604.

> When I try to export some nodes with ExportDocumentView I get a DOMException with Jackrabbit
1.5.2. Version 1.4.6 works fine. Xerces version was 2.8.1.
> Code:
> Document document = documentBuilder.newDocument();
> Element exportElement = (Element) document.appendChild(document.createElement("Export"));
> Result result = new DOMResult(exportElement);
> TransformerHandler transformerHandler = saxTransformerFactory.newTransformerHandler();
> transformerHandler.setResult(result);
> session.exportDocumentView(workflowNode.getPath(), transformerHandler, true, false);
> Exception:
> org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object
in a way which is incorrect with regard to namespaces.
