>>Are there some utilities for generating the client stubs
You bet, there are plenty. From within SG, go to Help and navigate to the references section where I list a few. The SG package also includes client demos for MSSOAP Toolkit and AXIS which is a java based solution. You'll find them under 'Tests'. I'm waiting for Don Baccus to chime in and make reference to TclSOAP<g>. As he's correctly pointed out, it's a viable solution for thing related to tcl and soap. As far as client stuff goes in SG, I thought about it. Something will eventually surface. I must admin, all client connectivity was performed from a win32 box (hmmmm, testing interoperability to my linux server from win32 - pretty cool.) Server to server connectivity would probably be helpful for scaled implementations. Despite a potential SG client solution, I'd encourage other types of client implementations since that's what SOAP's all about.
Concerning complex types, I'll be handling that within the near future. I've been through complex types in other SOAP services I manage; therefore, I'm not concerned about its complexity.
Thanks for the compliments. I hope the package provides the connectivity we're hoping for. My personal goal was to get automated access to the ecommerce package. I'm looking forward to getting there.
