com.ctc.wstx.stax.WstxInputFactory cannot be cast to javax.xml.stream.XMLInputFactory

在weblogic10.3上部署war包时总是遇到下面的问题，没有解决，不知道是怎么回事。

 Deploying a web application (using Spring 3.0) on Liferay running in WebLogic 10.3.2.0, we get following exception:

不过在查了一些资料后，发现weblogic10.3确实存在这样的问题，据说这是weblogic10.3的一个bug，对于这个问题，我的解决方案是重新安装了一个weblogic9.0，然后部署可以成功。估计就是weblogic版本和JDK版本的问题。
