How to call java service using WCF without app.config

Question

Hi
I have the following headers in the app.config
<wsse:Security s:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<wsu:Timestamp wsu:Id="Timestamp-02be6222-d34d-4c19-bb35-f4e98cc18534" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsu:Created>2010-06-28T13:29:03</wsu:Created>
<wsu:Expires>2010-06-28T13:59:03</wsu:Expires>
</wsu:Timestamp>
<wsse:UsernameToken wsu:Id="SecurityToken-3f7f983f-66ce-480d-bce6-170632d33f92" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:Username>
</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">
</wsse:Password>
<wsse:Nonce>L8o3HoilQh2i4kkwlGTY4w==</wsse:Nonce>
</wsse:UsernameToken>
</wsse:Security>
The client asked me to ommit the app.config and do the above configuration from code
How do I do that?
I tried OutgoingMessageHeader, but when i call the java web service (that is not not implemented by myself) always returns "Error readin XMLStreamReader"
please advisse,
