I am writing a federation provider that accesses Oracle using MyBatis.
### Cause: java.lang.RuntimeException: XPathFactory#newInstance() failed to create an XPathFactory for the default object model:
http://java.sun.com/jaxp/xpath/dom with the XPathFactoryConfigurationException: javax.xml.xpath.XPathFactoryConfigurationException: No XPathFactory implementation found for the object model:
http://java.sun.com/jaxp/xpath/dom at org.apache.ibatis.exceptions.ExceptionFactory.wrapException(ExceptionFactory.java:26)
at org.apache.ibatis.session.SqlSessionFactoryBuilder.build(SqlSessionFactoryBuilder.java:54)
The federation provider jar is a big fat jar that includes all its dependencies.
