I am trying to deploy Apache Continuum on JBoss 6.
The war is apache-continuum-1.3.6.war
I get this error :
Deployment "vfszip:/D:/NPCT/Developpement/jboss-18.104.22.16800216-M2/server/default/deploy/apache-continuum-1.3.6.war/" is in error due to the following reason(s): java.lang.LinkageError: loader constraint violation: when resolving overridden method "org.apache.commons.configuration.XMLConfiguration$1.error(Lorg/xml/sax/SAXParseException;)V" the class loader (instance of org/jboss/classloader/spi/base/BaseClassLoader) of the current class, org/apache/commons/configuration/XMLConfiguration$1, and its superclass loader (instance of <bootloader>), have different Class objects for the type org/xml/sax/SAXParseException used in the signature
Does anyone know what's wrong and how to fix it ?
Thanks for helping.
