異常摘要:
JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/D:/tomcat-6.0.18/webapps/xwiki/WEB-INF/lib/jaxb-impl-2.1.10.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.5.0/docs/guide/standards/)
運行環境:
Jdk1.6+tomcat6.0.18+windows xp sp3+xwiki

罪魁禍首:
jaxb-impl-2.1.10.jar
jaxb-api-2.1.jar
解決方案:
在jdk6的環境中,若在web應用中使用以上兩個jar包,你需要把jaxb-impl-2.1.10.jar放到jdk的lib目錄下即可解決該異常
