BIRT is missing SOAP request parameters

I setup a running webservice (SOAP via JAX-WS) which has already some working Java and C# clients without any issues.

When I try to use the same SOAP webservice with BIRT I found out that in the generated request it is missing the parameters for the functions.

How can I help BIRT find the missing method parameters?

Generated Request (Missing parameter)

<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
        <m:getMachine xmlns:m="http://machine.soap.webservices.product.company.at/">
        </m:getMachine>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Request that I would expect (With parameter)

<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <SOAP-ENV:Body>
        <m:getMachine xmlns:m="http://machine.soap.webservices.product.company.at/">
            <m:machineId>&?machineId?&</m:machineId>
        </m:getMachine>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
