web services - ClassCastException for xml security (TransformC14NExclusive) -

-

i have implemented web service cxf application (jdk 1.6.24) , runs on jboss 5.1.0 fine. after time web service not working throws following exception

the workaround have used removing tmp, data , work folder jboss. works fine afterwards, until throws error again later.

most cause of exception same class loaded multiple classloaders.

you have review how package application.

jboss has cxf jars , visible default application. if package cxf jars application, must understand jboss classloading rules , how tweak them.
