Constructor Detail

WebXmlParser

public WebXmlParser(ClassLoader commonCL)

Method Detail

parseStreamToXML

protected Document parseStreamToXML(File webXmlFile)

Get a parsed XML DOM from the given inputstream. Used to process the web.xml application deployment descriptors. Returns null if the parse fails, so the effect is as if there was no web.xml file available.

resolveEntity

public InputSource resolveEntity(String publicName,
                        String url)
                          throws SAXException,
                                 IOException

Implements the EntityResolver interface. This allows us to redirect any requests by the parser for webapp DTDs to local copies. It's faster and it means you can run winstone without being web-connected.
