Ragy Eleish commented on JCR-217:
---------------------------------
I did more research the dependency on xerces is in more files than just QNAME
they are as follows:
contrib\jcr-ext\src\java\org\apache\jackrabbit\session\SessionNamespaceRegistry.java
contrib\jcr-ext\src\java\org\apache\jackrabbit\xml\DocumentViewExportVisitor.java
org\apache\jackrabbit\core\LocalNamespaceMappings.java
org\apache\jackrabbit\core\NamespaceRegistryImpl.java
org\apache\jackrabbit\core\SessionImpl.java(1009):
XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
org\apache\jackrabbit\core\WorkspaceImpl.java(687):
XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
org\apache\jackrabbit\core\query\lucene\LuceneQueryBuilder.java
org\apache\jackrabbit\core\util\ISO9075.java
org\apache\jackrabbit\name\Path.java
org\apache\jackrabbit\name\QName.java
Most of the dependency is on isValidNCName, with the following exceptions
- SessionImpl and WorkspaceImpl they specify the xerces parser directly.
- ISO9075 and DocumentViewExportVisitor depend on some other methods in the
Xerces' XMLChar class.
> class org.apache.jackrabbit.name.QName has a hardcoded dependency on Xerces

> Key: JCR-217
> URL: http://issues.apache.org/jira/browse/JCR-217
> Project: Jackrabbit
> Type: Bug
> Versions: 1.0
> Reporter: Ragy Eleish
> Priority: Critical
>
> The class org.apache.jackrabbit.name.QName, has an unneeded dependency on
> Xerces which make it difficult to work with the XML parser or ones choice.
> The dependency (on line 246) is on the method "XMLChar.isValidNCName" only. I
> suggest one of the following solutions
> - Copy the implementation of this method to the QName class, it is a very
> simple implementation.
> - Use the mehtod provided in JAXP 1.3 javax.xml.XMLUtils.isValidNCName, which
> will create dependency on JAXP 1.3 though. JDK 1.5 ships with JAXP 1.3
> This dependency is causing us alot of trouble since we need to use another
> parser that is optimized for large XML data.
