Struts1.3.5でActionServlet起動時にSAXNotRecognizedException

Struts起動時にエラーが発生。ActionServletが起動しない。

原因 

「http://d.hatena.ne.jp/Ochotona/20061018」にあった「http://ml.seasar.org/archives/seasar-user/2005-September/000722.html」を参考にすると、設定ファイルを読み込むときにStrutsが使っているDigesterは、xercesというXMLパーサがあるとそれを使ってしまい、このエラーが出ると考えられる（なんじゃそりゃ）。

Xercesは消せないのでどうしようか考え中。
