public class SystemIDResolver

extends java.lang.Object

This is a generic utility for resolving URIs, other than the fact that it's declared to throw TransformerException. Please see code comments for details on how resolution is performed.

Method Detail

getAbsoluteURIFromRelative

public static java.lang.String getAbsoluteURIFromRelative(java.lang.String uri)

Get absolute URI from a given relative URI.

The URI is resolved relative to the system property "user.dir" if it is available; if not (i.e. in an Applet perhaps which throws SecurityException) then it is currently resolved relative to "" or a blank string. Also replaces all backslashes with forward slashes.

Parameters:

uri - Relative URI to resolve

Returns:

Resolved absolute URI or the input relative URI if it could not be resolved.
