URGENT Header issue

hi all,

i posted a similar threat sometime ago with regards to a header issue.

I am exposing a webservice as Provider in IS, i had some issues with QName’s and managed to fix it but i am still getting the following problem
when i try to send a request to IS.
[ISS.0088.9356] One or more required Headers “http://www.comp.com/services/1.0/:login_header” are not present in the SOAP request.

the wsdl i have which i use to expose the ws its a bit complicated but i have tried easier ones with no luck.

Has anyone come across this error before?
