how to access SCA c++ componet via web service?(about SCA, AXIS2/C)

[jing hu]

Now I have a simple SCA C++ component named Calculator. I just can access the simple component locally.

I want to define the SCA component binding with web service, so I add the below code in the Calculator.composite.

    
<service name="CalculatorService">
    <binding.ws/>
    <reference>CalculatorComponent/CalculatorService</reference>
</service>

And then I start the Axis2/C HTTP server, I have set all the environment variables,such as

   
set TUSCANY_SCACPP=C:/tuscany_sca 
set TUSCANY_SDOCPP=C:/tuscany_sdo 
set AXIS2C_HOME=C:/axis2c-bin-0.96-win32 
set PATH=%PATH%;C:/tuscany_sca/bin;C:/tuscany_sdo/bin;C:/axis2c-bin-0.96-win32/lib 
set TUSCANY_SCACPP_SYSTEM_ROOT=C:/tuscany_sca/samples/CppCalculator/deploy 
set TUSCANY_SCACPP_DEFAULT_COMPONENT=sample.calculator.CalculatorComponent 
cd %AXIS2C_HOME%/bin/ 
./axis2_http_server.exe 
 

but when I type the address:http://localhost:9090/axis2/services in the web browser, I find the numbers of service in the axis2 doesn't changed(the port of axis2 is 9090).

So My question is :
1: can the above code define Calculator component with web service?
2: should I need to make a dir named Calculator in the axis2/services directory. if this, the code "<binding.ws/> " has no function.
in the axis2/services directory, I just need a service.xml and .dll or .so file. And I don't need any *.composite or *.componentType file any more.
3. whethr or not the address(http://localhost:9090/axis2/services) can display the sca component services? because I don't find any clue about how to deploy the Calculator component in axis2.


I am a new hand of SCA and Axis2/c. Any comment will be welcome! Thanks very much!

Hi!
Try using the uri attribute in the <binding.ws> element, like this:

<binding.ws requires="SOAP.1_2" uri="http://localhost:8085/CalcService" />

I have only played around with the Tuscany and Java and, as far as I know, you should not have to configure the web service stack used by Tuscany (Axis).
If you create a project that is using Tuscany, then you have to retain the composite and componentType files.

For more details, I recommend the SCA specifications. For C++ they can be found at: http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=sca-c-cpp
I can also recommend the Tuscany User's mailing list where many of the friendly Tuscany developers answer questions.
Best wishes!

When I try to access the SCA component via Web Service. The Axis2/c HTTP server will have a segmentation fault and exit!

I also try SCA Java Component. It will be ok. I can access the sca component via Web Service.

I will read the resource you recommend with reserve.

Thanks very much.
