Composite without an implementation causes BuilderConfigException
-----------------------------------------------------------------
Key: TUSCANY-1075
URL: https://issues.apache.org/jira/browse/TUSCANY-1075
Project: Tuscany
Issue Type: Bug
Components: Java SCA Core
Affects Versions: Java-M2
Environment: Windows XP SP2, Tuscany M2 distribution
Reporter: Andrew Schofield
Priority: Minor
Fix For: Java-SCA-M3
I've built the webapp/helloworldws sample and deployed it on Tomcat. I've also
managed to invoke it using the standalone/helloworldwsclient sample. But, I was
surprised to find that there was a (trivial) implementation in the composite of
the client (HelloWorldServiceComponent) which just delegates the method calls
to the back-end service. I'd really expected to write SCDL for a composite
which wired a service directly to a reference with a Web-services binding. This
would give a way of connecting an SCA client to an existing Web service without
any implementation coding.
Here's the SCDL that I tried:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
xmlns:system="http://tuscany.apache.org/xmlns/system/1.0-SNAPSHOT "
name="helloworldwsclient">
<dbsdo:import.sdo xmlns:dbsdo="
http://incubator.apache.org/tuscany/xmlns/databinding/sdo/1.0-incubator-M2";
location="wsdl/helloworld.wsdl"/>
<service name="HelloWorldServiceComponent">
<interface.wsdl xmlns:wsdli="http://www.w3.org/2006/01/wsdl-instance "
interface="http://helloworld#wsdl.interface(HelloWorld) "
wsdli:wsdlLocation="http://helloworld wsdl/helloworld.wsdl" />
<reference name="helloWorldService">HelloWorldService</reference>
</service>
<reference name="HelloWorldService">
<interface.wsdl xmlns:wsdli="http://www.w3.org/2006/01/wsdl-instance "
interface="http://helloworld#wsdl.interface(HelloWorld) "
wsdli:wsdlLocation="http://helloworld wsdl/helloworld.wsdl" />
<binding.ws endpoint="
http://helloworld#wsdl.endpoint(HelloWorldService/HelloWorldSoapPort)"
location="wsdl/helloworld.wsdl" />
</reference>
</composite>
And here's the exception that I got (using Tuscany Java M2):
