Webservice call from PB 11.5 Desktop Version

Hi guys

I work with PowerBuilder 11.5 Desktop version and I understand I cannot use web services with it ( Only Enterprise does I believe ).

I wonder if I can create a non-powerbuilder code to call a web service ( say java, .NET, etc ) and have this code called from PB as an external function with passing parameters such as an XML file, text structure or something similar.

Yes I would love to have PB 12.5 Enterprise version to have life solved in a click, but I'm sticking to my current tools.

Do you have an idea for this tricky requirement?

Thanks so much
