Re: SCA and BPEL
Hello Guys..
As discussed earlier about Integration of SCA(Apache Tuscany) and BPEL
(Apache Ode),
I have started with a bpel container for Apache Tuscany(SCA).
Also i have attached a small readme file .
And a test case file also.
The link for the attached source is :
http://issues.apache.org/jira/browse/TUSCANY-897?page=all
Comments:
Things to do :
- need to figure out a better way than instantiating the server for every
component
- need to bring in databinding into the invoke method to be able to convert
java objects to xml that can be sent over ODE requests and also do the
reverse for the response.
Guys I need your feedback on this !!! Plz share your ideas . !!.
Sam..Tam...

Re: SCA and BPEL
Posted by Matthieu Riou <ma...@gmail.com>.
Hi Sam,
I've had a look at your implementation and played with a couple of things on
my side as well. I think I have a much better idea of how things can play
with each other now and how to solve your problems.
- For server instantiation, you should create a separate component for it
with @Init and @Destroy annotations. I've made a rough implementation of it
and I think you could take it and start from that. You'll just have to add
the component as a system implementation in your bpel.system.cdl. I'll
attach the java file to the same Jira issue. Then you can have this injected
in the BpelComponentBuilder using a constructor like:
public BpelComponentBuilder(@Autowire BpelServerLoader serverLoader) {
_server = serverLoader.getServer();
_store = serverLoader.getStore();
}
That should fix the server instantiation problem.
- For the binding part you will need to go through a real remote web service
invocation. Check of the Tuscany helloworldws is structured with the
sample-helloworldws web application being deployed in Tomcat and the client
sample-helloworldwsclient calling it remotely. I think you can even reuse
the client almost as is. However the server side should change to something
like:
<service name="HelloWorldBPELService">
<interface.wsdl interface="
http://ode/bpel/unit-test.wsdl#wsdl.interface(HelloPortType)"
wsdli:wsdlLocation="http://ode/bpel/unit-test.wsdl
HelloWorld2.wsdl"/>
<binding.ws endpoint="
http://ode/bpel/unit-test.wsdl#wsdl.endpoint(HelloService/HelloPort)"
location="HelloWorld2.wsdl" />
<reference>HelloWorldBPELComponent</reference>
</service>
<component name="HelloWorldBPELComponent">
<bpel:implementation.bpeldepDir="/home/dusty/Dev/Projects/tuscany/sca/services/containers/container.bpel/src/test/resources/HelloWorld2"
serviceId="http://ode/bpel/unit-test.wsdlHelloService"/>
</component>
Again check the Tuscany sample-helloworldws service declaration, it's almost
the same except for the implementation that will be BPEL in our case instead
of java. You can even use the same type of SDO databinding So you will need
to package the BPEL container on the server side in Tomcat and that should
get loaded.
Let me know if you need more,
Matthieu
