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.
