The build of JBoss 5 that I have been using from February, 2006 generates WSDLs where the parameter ordering is alphabetical. The latest (as of March 9th) version of JBoss WS orders parameters as they appear in the method declaration.
It's not a problem now (I can rebuild proxies), but if the behavior changes (and can't be set one way or the other) client apps will fail.
Will the behavior in the future be as declared or alphabetical?
The order is defined by the abstract contract (wsdl + schema), which may not be the alphabetical order
