The kernel also loads any<BR> +extensions found in the Tuscany extensions directory (found in the<BR> +directory specified by the TUSCANY_SCACPP env variable). The kernel<BR> +inspects the .composite files and checks that any required extensions<BR> +that the SCA app uses are loaded, works out how the components are<BR> +wired together, and then passes the details of the composite to the<BR> +appropriate extensions. E.g. if the SCDL contains a<BR> +<implementation.python> element, the contents of that element are<BR> +passed to the Python extension which will load a defined script, etc.<BR> +When the SCA app is invoked (via a local client call or a SOAP or REST<BR> +service binding being called) the kernel uses the appropriate<BR> +extension to invoke the right methods in the component implementation<BR> +code.</P> + +<P>The language binding extensions (C++, Ruby, Python, PHP) provide<BR> +wrapper and proxy code. The wrapper code wraps the component<BR> +implemented in that language, initialising the component<BR> +implementation, converting method arguments to the correct types and<BR> +invoking the defined method with the converted arguments. The proxy<BR> +code allows the component to call it's references, providing objects<BR> +that look like standard objects in the component language, but which,<BR> +when called, convert the method arguments from the language types and<BR> +invoke the referenced component's wrapper code to invoke the component<BR> +itself.</P> + +<P>The service and reference binding extensions (SOAP/Axis2C, REST)<BR> +provide service and reference code. The service code allows Tuscany to<BR> +run within a container as a service that can be invoked (e.g. as an<BR> +Axis2C SOAP web service). The reference code allows Tuscany to call<BR> +other services (that may or may not be other Tuscany services) using<BR> +that technology to make the call out (e.g. a SOAP call to a Web<BR> +Service).<BR> +See the various samples we have for examples of all this.</P> +</TD></TR></TBODY></TABLE> + </DIV> + </DIV> + </DIV> + <!-- pageContent macro end --> + + </TD> + </TR> + </TABLE> + + <!-- footer macro --> + <SCRIPT src="http://www.google-analytics.com/urchin.js" type="text/javascript"> + </SCRIPT> + <SCRIPT type="text/javascript"> + _uacct = "UA-1174707-5"; + urchinTracker(); + </SCRIPT> + + <A href="http://www.statcounter.com/" target="_blank"><IMG src="http://c26.statcounter.com/counter.php?sc_project=2619156&java=0&security=94bd7e7d&invisible=0" alt="website stats" border="0"></A> + + <DIV class="footer"> + Copyright � 2003-2012, The Apache Software Foundation </BR> + Apache Tuscany and the Apache Tuscany project logo are trademarks of The Apache Software Foundation. + </DIV> + <!-- footer macro end --> + + </BODY> +</HTML> |
