I've run into a snag trying to play friendly with some ColdFusion developers where I work and was hoping someone in the JUG would have some input. My situation is this: I am writing a web application that draws resources from several other tools within my department (Learning Technologies at the U of A). All players are willing to create web services for me to talk to. So my thought was "gee, it would be great if everyone shared the same WSDL file and the others implemented their services to match it". [Cut to scene of streets paved with gold, ethereal harp music and cats and dogs living in harmony.]
My first group of collaborators are ColdFusion developers. They are adept at creating web services. Unfortunately they are only adept at making web services that they control - making a service that fits with someone else's WSDL seems a stretch too far. In my pollyannaish way I like to think that it should be possible to take the JAXRPC-generated WSDL that fits my wonderful Java object model and run a magical script that will generate template code for implementing the service in ColdFusion. Likewise, I like to believe, it should be possible to run a similar script on the Java side that would create (potentially poorly factored) Java interface and class templates that would implement the service described by the WSDL. Barring these fantastical scripts, I would like to believe that all WSDLs are at least mutually producable/expressable by the various leading platforms for web service development. As I grow more hardened and jaded I begin to believe this is more wishful thinking. In Java my model has many Exception objects in a nice neat semantically organized hierarchy. But the CF developers seem stymied and unable to produce CF components that generate WSDL with anything other than CFInternalException (or something) messages - and no real subclasses thereof. There is an expressed willingness to reverse engineer the CF components from the WSDL if all elements of the WSDL can be reliably bound - but so far there have been no breakthroughs. So far I've wished real hard, crossed my fingers and held my breath. Neither these nor scouring newsgroups and tutorial sites have yielded the tools nor tutorials I imagine. So I thought to put this to the group. Has anyone ventured to implement the same web service on different platforms (ideally JAXRPC and ColdFusion)? Am I the only wingnut out there who wants to treat WSDL as an interface definition for multiple services (I *can't* be, but hope I'm not the only one here)? Is it possible to get ColdFusion to produce errors (SOAP fault messages) that match up with those in a Java-derived WSDL document? I'd be interested in whatever experieces y'all have had. -Duffy P.S. If I put down a vote for Dennis for the full meeting, do I get to ask obnoxious questions about sharing WSDL files between platforms ;) Either way put me down +1 for Dennis and +1 for 'Advanced Issues' -- --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
