" I have been able to walk thru the tutorials and generate the resources to make them work as described. But, I am having a heck of a time trying to determine how I can use them in a production application. I have the Stock Quote web service working using the client proxy that was generated in WDSc. So, now I have proven that the resources can be generated by WDSc. Can RPG somehow be used to be a web service consumer ? Or must Java be used. Can the Java methods generated by the web service be prototyped in an RPG to call them and invoke the web service ? I would ultimately like to use the UPS Online Tools to update the shipping rate in DB2 on the iSeries. WDSc gets me part of the way there. But, I'm still not sure how I tie it all together.
