WSE2 and customised Soap Header

[Hai Ta]

Please help
We have been stuck for the past 2 weeks in trying to implement a
webservice using WSE2 such that consumer can access with the following
soap header.
<?xml version="1.0" encoding="UTF-8"?>

<env:Envelope xmlns:env="http://www.w3.org/2002/06/soap-envelope">
<env:Header>
<isa:Service xmlns:isa="http://www.isa.com.au" env:mustUnderstand="1"
Type="Request">ServiceCode</isa:Service>
<isa:Authentication>
<isa:Sender env:mustUnderstand="1">
<Id UniqueID="ISA0101" Type="IsaCode">AAA Company Name</Identifier>
<wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext">
<wsse:UsernameToken>
<wsse:Username>UserID</wsse:Username>
<wsse:Password>password</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</isa:Sender>
<isa:Recipient env:mustUnderstand="1">
<Id UniqueID="ISA0003" Type="IsaCode">BBB Company Name</Identifier>
</isa:Recipient>
</isa:Authentication>
<isa:MessageReference env:mustUnderstand="1">
<isa:Id UniqueID="12345" Type="isacode"/>
</isa:MessageReference>
</env:Header>
<env:Body>
...
</env:Body>

</env:Envelope>

Can this be achieved or is there a better alternative? A point in the
right direction would be much appreciated. Thanks in advance.
