From: Doug Tidwell/Raleigh/IBM To: [EMAIL PROTECTED] Date: 06/17/2008 12:23 PM Subject: Reworking the calculator samples Gang, I've written a graphical front-end to the calculator samples. There's a Swing front-end with the usual calculator buttons, and I've added a menu that lets you select the .composite file you want to use. I'm using this in a hands-on lab to emphasize that you can change the infrastructure beneath an application without changing the application. To build this, I've taken the code from the existing calculator demos and integrated them into a single Eclipse project. I'm currently working on deploying the calculator as a Web service. What surprised me is that whenever I run the application, I get an error if there's anything wrong with any .composite file in the Eclipse project. My assumption was that Tuscany wouldn't load a .composite file unless I created an SCADomain with it. As it is, Tuscany loads every .composite file it can find, then complains if something's wrong with one of them, whether I use that .composite file or not. Is this an implementation decision, or did I miss something in the spec that says an SCA runtime should work this way? I'd appreciate any insight on this. I'm working around the problem easily enough, but the behavior surprised me. I'm using tuscany-1.1-incubating, fwiw. ...And yes, I'll post all the materials for the hands-on workshop soon, I promise.
