I spent most of today trying to get the RestCalculator sample up and
running on Windows. 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!
Cheers

I finished setting up a complete Windows environment with Curl and
Httpd yesterday evening. I noticed that there are many Curl
distributions available, so I picked an "MSVC development
distribution" and will give it a try today.
Andy,
The RestCalculator sample now works on Windows, with the following
configuration:
- an MSVC based Libcurl distribution (at
http://curl.haxx.se/download.html, the one before the last one at the
bottom of the page, more precisely
libcurl-7.15.1-msvc-win32-ssl-0.9.8a-zlib-1.2.3.zip from Chris Drake).
- an update to the VSExpress project to link with the import lib from
that Libcurl distro
- an update to the HTTPD conf to specify a DocumentRoot (and load the
Mime and Dir HTTPD modules into the server), I added the gen of this
conf to the startserver.bat script.
So if you download the Libcurl distribution above and update from the
SVN head, it should work now.
I started to update the scripts and conf in the RestCustomer sample as
well but it doesn't work yet, I'll continue to work on it later this
evening.
