Can we pass J2EE security context to a xdp form?

[baijingyu]

I am doing a J2ee application developement that a user will logon to the application and open the form,fill it and press submit button to call a web service. The form submit button is pointing to a web service that needs security authentication such as:

<wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken>
  <wsse:Username>user</wsse:Username>
  <wsse:Password>password</wsse:Password>
  </wsse:UsernameToken>
  </wsse:Security>

I am wondering how to pass the security header info to the SOAP header so user doesn't have to type user name and password again when hiting submit button since he already logon to the apllication. Can and how the LiveCycle Forms server take the header info from Java API call and fill the submit button SOAP security header?  I got stucked here and I would really appreciate if someone can guide me on this.  Thanks.

Is my question in a wrong topic? I want to know how your guys handle the forms web service call with wsse:UsernameToken authentication enabled. Can forms API be used to pass the security header info? Thanks.
