Re: Run a program on iSeries from the web

["Michael Ryan" <michaelrtr@xxxxxxxxx>]

So Walden...what tools are available on iSeries for web services? I've seen
some stuff about Axis on Tomcat, but I'm wondering about a Websphere shop.
Are the tools built in? How much code is needed to actually do the work? In
other words, does Websphere have 'stuff' that takes the incoming web service
call, parses out the salient data items, call the (RPG) program on the
iSeries, then take the returned data (stream file, user space contents, ?),
dress it up with the appropriate XML, and send it back?
