Re: Xerces and Xalan packaging

[Joseph Kesselman]

Xalan is essentially using the standard package from the XML-Commons Apache project, packaging it as xml-apis.jar

Xerces also uses the files from that source, but trims away those which they don't think they need, to produce their xmlParserAPIs.jar.

Theoretically, if the former is on your classpath you shouldn't need the latter (assuming your Xerces and Xalan are otherwise in synch.)


The question of whether saving the bytes in xmlParserAPIs.jar is really worth the cost of having another jarfile to worry about is an ongoing debate.
