SOAPAction is null with java/ws-client vs. no token with jav

I am trying to send a request though soap

I tried 2 method:

1. I use java/ws-client, however the SOAPAction is null so the message always fail

2. I tried to use java/ws-rawclient since you can add header SOAPAction there, but however, this needs a token and there is no place to setup the token at all

so any suggestion about  what can be one to get this done? TIA
