好像我过去曾经做过一次这样的事情,但是我找不到任何关于我做了什么才能让它发挥作用的参考.
我有一个Web应用程序,我想在其中指定一个不同于我的web服务器/ jre提供的JAXB实现.我从maven下载了相应的工件,看到jar在我的战争中正确打包,但是,当我启动我的Web应用程序时,我发现它仍在使用捆绑的JRE实现.
我依旧记得有关我可以配置的属性文件的一些内容,但是找不到它需要如何配置的引用.此外,如果我想要使用的实现是相同的(只是一个较新的版本),类名将与在JRE中打包相同.如何指定我想使用WAR中捆绑的那些？
编辑
我目前正在运行JBoss 7.0.2,使用Oracle JDK 1.6_0_27,JRE附带的JAXB RI(我认为它是v2.1).我正在尝试升级到JAXB RI 2.2.5(在MvnRepository上找到).
我今天早上做了一点挖掘,发现我的日志中有一条奇怪的错误消息:

Ivy 用于依赖管理，其中我包括以下内容

我看过有关此主题的其他帖子，但他们的答案没有多大帮助。我尝试使用 jaxb.properties 但这并没有改变行为。
