Subject [jira] Commented: (JCR-1952) DOMException: NAMESPACE_ERR thrown when exporting document view
Date Thu, 19 Feb 2009 10:11:01 GMT

    [ https://issues.apache.org/jira/browse/JCR-1952?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12674950#action_12674950
] 

Jukka Zitting commented on JCR-1952:
------------------------------------

The workaround is to look for and remove the Xalan jar from the repository classpath. The
export works fine with the built-in JAXP libraries in all JDKs we've tested, but it looks
like other TransformerFactory implementations (like the one in the Xalan versions reported
here) break the export.

I'm still not sure how to best resolve this. I'm inclined to either revert back to the 1.4
code (with the potential of introducing other regressions) or going with a custom XML serializer
that doesn't depend on any JAXP libraries (which would be a notable new block of potentially
buggy code).

> 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.
