Class PreventLocalEntityResolver

Object

PreventLocalEntityResolver

All Implemented Interfaces:

Serializable, EntityResolver, EntityResolver2

public class PreventLocalEntityResolver
extends Object
implements EntityResolver2, Serializable

EntityResolver implementation to prevent use external entity resolution to local files.

When parsing an XML entity reference to a local file a SAXException is thrown, which can be handled appropriately.

This implementation is both recommended and the default returned by GeoTools#getEntityResolver().

getExternalSubset

resolveEntity

public InputSource resolveEntity(String name,
                                 String publicId,
                                 String baseURI,
                                 String systemId)
                          throws SAXException,
                                 IOException

Tells the parser to resolve the systemId against the baseURI and read the entity text from that resulting absolute URI. Note that because the older DefaultHandler.resolveEntity(), method is overridden to call this one, this method may sometimes be invoked with null name and baseURI, and with the systemId already absolutized.

Throws:
