Validating XML message against WSDL

Hi all,

I have a very simple question, but I can't figure it out. I have a WSDL, and I have an XML message. I'd like to validate this message against the WSDL with IntelliJ, but I have no idea how to make that work. I have a file which has the XML, one with the WSDL, even one with the Schema, one with the complete SOAP request, but I have no idea how to combine them and make validation work. Does anyone here have a an X step guide to making it work? I have it working in SOAP UI, but I'd rather use IntelliJ.
