[keycloak-user] Issue with XPathFactory

Hi all, I am writing a federation provider that accesses Oracle using MyBatis. I get the following error when MyBatis is trying to read its xml configuration: ### Cause: java.lang.RuntimeException: XPathFactory#newInstance() failed to create an XPathFactory for the default object model: http://java.sun.com/jaxp/xpath/dom <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 <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. Any ideas? Thank you Maria
