Hi, I've just started using Tuscany and I've been kicking around some of the samples to see what they do. I've managed to make them work without problems but I hit a snag when I tried to change one in particular.
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): Exception in thread "main" org.apache.tuscany.spi.builder.BuilderConfigException: No interceptor for operation [getGreetings] at org.apache.tuscany.core.builder.ConnectorImpl.connect(ConnectorImpl.java :336) at org.apache.tuscany.core.builder.ConnectorImpl.connect(ConnectorImpl.java :278) at org.apache.tuscany.core.builder.ConnectorImpl.connect(ConnectorImpl.java :389) at org.apache.tuscany.core.builder.ConnectorImpl.connect(ConnectorImpl.java :163) at org.apache.tuscany.spi.extension.CompositeComponentExtension.prepare( CompositeComponentExtension.java:460) at org.apache.tuscany.core.deployer.DeployerImpl.deploy(DeployerImpl.java :86) at org.apache.tuscany.core.runtime.AbstractRuntime.deployApplicationScdl( AbstractRuntime.java:136) at org.apache.tuscany.runtime.standalone.host.StandaloneRuntimeImpl.initialize( StandaloneRuntimeImpl.java:87) at org.apache.tuscany.launcher.MainLauncherBooter.main( MainLauncherBooter.java:83) Can anyone enlighten me about the cause of the problem? I think that a composite without an implementation should be OK, so I hope that it's just my SCDL at fault. Thanks in advance, Andrew Schofield
