Greetings! I'm posting this reply, to let you know that this issue arises when implementing WS with delphi clients. Delphi is somehow always using default namespaces and within that type of xml formulation, simple method parameters normally defined as: <q0:getUserByCredentials> | <arg0 xmlns="">kumy</arg0> | <arg1 xmlns="">mah</arg1> | <q:/getUserByCredentials> are transmited in this form from delphi: <getUserByCredentials xmlns="some_namespace"> | <arg0 xmlns="">k</arg0> | <arg1 xmlns="">m</arg1> | </getUserByCredentials> After parsing the last case, these parameters(arg0 and arg1) appear empty. Is there any recomendation how to work around this issue for now? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027453#...
