I hit a few issues: Libcurl - this was the major one. The extension built fine but died on the restclient side of the sample when it tried to initialise libcurl (via the curl_global_init() call). I tried all the different kinds of libcurl for Windows that are available at [1] but I got the same result with all of them. Eventually I built my own from source, and that died too until I built it via VS Express rather than the command-line build! At this point it all started working and I began to see messages appearing on the server. To have to download the src and build it would be a huge hassle for users that we *really* want to avoid. It may just be that I was doing something wrong with my libcurl stuff but I couldn't see what - I was just getting the windows "it's died" message that you normally get when libraries don't like each other. If anyone else could try it out and see what happens for them with the windows libcurl binary distros it would be appreciated!
I wonder if our building with vc8 is causing the incomaptibility. We have had issue before with dll's being built against different versions of the msvc runtime dlls. REST service - after all the shenanigans with libcurl, I hit an issue
with tuscany_sca_mod_rest.dll that I didn't have time to get past. In ModREST.cpp the request->path_info is coming out as /htdocs/rest/sample.calculator.CalculatorComponent/CalculatorService/div, but it looks like the code expects it to be something like /sample.calculator.CalculatorComponent/CalculatorService/div - this meant that the runtime was looking for a component named htdocs and a service named rest! I assume you get the path without the /htdocs/rest part on Linux, although it's a bit odd that the data is different on Windows.. I'm on Apache HTTPD 2.2.3 - is that the same version you're using? Anyway, I'm doing a presentation on Tuscany at the Javapolis conference in Belgium next week, so I'll be preparing for/going to that over the next few days, and won't have much time to progress this or the HttpdBigBank sample. I've put the windows deploy/run scripts for RestCalculator on svn, so if anyone does fancy trying it out I'll be interested in your results!
