jdk6自带的jabx2.0与cxf使用的jabx2.1冲突的问题-优快云博客

本文解决了一个在Tomcat环境下部署应用时遇到的JAXB 2.1 API加载错误的问题。该错误提示表明JAXB 2.0 API从引导类加载器加载，但当前实现需要2.1 API。通过将jaxb-api.jar放置在endorsed目录中解决了此问题。

应用在部署的时候报出这个异常

Caused by: java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/usr/local/tomcat/webapps/sso/WEB-INF/lib/jaxb-impl-2.1.6.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/)
