resolveEntity

public org.xml.sax.InputSource resolveEntity(java.lang.String publicId,
                                             java.lang.String systemId)

Allow the application to resolve external entities.

The strategy we follow is:

We first check whether the DTD points to a well defined URI, and resolve to our internal DTDs.

If the systemId points to a file, then we attempt to read the DTD from the filesystem, in case they've been modified by the user. Otherwise, we fallback to the built-in DTDs inside jPOS.

Specified by:

resolveEntity in interface org.xml.sax.EntityResolver

Parameters:

publicId - The public identifier of the external entity being referenced, or null if none was supplied.

systemId - The system identifier of the external entity being referenced.

Returns:

An InputSource object describing the new input source, or null to request that the parser open a regular URI connection to the system identifier.

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

java.io.IOException - A Java-specific IO exception, possibly the result of creating a new InputStream or Reader for the InputSource.
