how to use soapUI as interface between java and delphi

Good Morning,

My name is Livio, I' m a delphi software developper.

I found myself in front of a big problem : I need to send files to a Java application using SOAP attachment technology.
The problem is that the way Delphi manage SOAPattachment is different from what the server I have to contact is used to.
I need to use a separate module written in Java to do that, since I have no experience with this language I' m looking for something that can operate as an external module to pass data to the Java Webservice server, I downloaded soapUI Pro trial version to see if it is possible to create a script that accept a normal text file as input and create the right web service call to the server.

I understand that SoapUI is made most of all for testing purpose, someone use this tool also for solving other kind of problems?

Regards
Livio Messina
