Is My File Attachment Request looking correct in SOAP?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:g........e" xmlns:xsd="http://io.java/xsd">

I use free version and this service is to upload file as attachment in SOAP.
So, I am new to soap and is this looking correct..if correct, what to enter in those.

if not, where its going wrong and how to fix it.

I am using Apache Axis2 and the service method is this

public String uploadFile(File gFileObj) {
                .....
  return "Yea the method has been correctly";
}

NOTE: some names in the xml are changed!!

Thanks
