Description

 

org.springframework.beans.BeanInstantiationException: Failed to instantiate  Factory method 'myXXXApi' threw exception; nested exception is org.apache.commons.logging

Caused by: org.apache.commons.logging.LogConfigurationException: The chosen LogFactory implementation does not extend LogFactory. Please check your configuration. (Caused by java.lang.ClassCastException: The application has specified that a custom LogFactory implementation should be used but Class 'org.apache.commons.logging.impl.LogFactoryImpl' cannot be converted to 'org.apache.commons.logging.LogFactory'. The conflict is caused by the presence of multiple LogFactory classes in incompatible classloaders. Background can be found in http://commons.apache.org/logging/tech.html. If you have not explicitly specified a custom LogFactory then it is likely that the container has set one without your knowledge. In this case, consider using the commons-logging-adapters.jar file or specifying the standard LogFactory from the command line. Help can be found @http://commons.apache.org/logging/troubleshooting.html.)
