An explanation that may help, hope it's not too late. The reason why your first approach results in your handler being called before the wsse one is that the latter is configured as a post-handler while yours is an endpoint-handler. You would need your handler to be a post-handler, however afaik this can only be achieved editing the jbossws configurations in standard-jaxws-client-config.xml. Speaking of the second approach, where did you do that call? where is the handlerChain instance from? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112677#...
