Date Fri, 07 Dec 2007 15:45:43 GMT
Replace Xerces/JAXP based (un)marshalling by XPP3 based implementation
----------------------------------------------------------------------

                 Key: JCR-1261
                 URL: https://issues.apache.org/jira/browse/JCR-1261
             Project: Jackrabbit
          Issue Type: Improvement
          Components: jackrabbit-webdav
    Affects Versions: 1.3.3
            Reporter: Felix Meschberger


Proposing to replace the current Xerces/JAXP based implementation of XML data unmarshalling
and marshalling to be replaced by a MXP ([1]) based implementation. MXP is an implementation
of the XML PullParser API [2] and provides a very mall footprint (120KB) and far better performance
than Xerces (my tests showed around 50% performance increase over Xerces for both unmarshalling
and marshalling, see also [3]).

Why do I care ? I would like to include WebDAV functionality into Sling and bundle is with
as little dependencies as possible ( the xpp3 lib might even be bundled into this project
to minimize dependencies). In addition, I think XML (un)marshalling performance is crucial
in any WebDAV solution. For this reason, this project can only win if we add a more performing
library.
