Assignee: Raymond Feng
> Unable to implement helloworld-ws-reference sample with complex types.
> ----------------------------------------------------------------------
>
> Key: TUSCANY-1432
> URL: https://issues.apache.org/jira/browse/TUSCANY-1432
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Samples
> Affects Versions: Java-SCA-M2
> Environment: Windows XP, JDK 1.5.0_11-b03, ant 1.7.0
> Reporter: David Haney
> Assignee: Raymond Feng
> Attachments: helloworld-ws-reference.zip

> I'm attempting to modify the helloworld-ws-reference example so that it is
> sending a complexType instead of simple types, and am having trouble with an
> exception that I can't explain. I wasn't able to find an example of this
> sort of thing in one of the other samples, so I've been trying to piece
> together the necessary changes, and I'm guessing I've just missed a step
> along the way.
> Here's what I've done so far (all file references are relative to
> <installdir>/samples/helloworld-ws-reference):
> - Modified the src/main/resources/wsdl/helloworld.wsdl So that the
> getGreetings operation contains a complexType:
> ...
> <element name="getGreetings">
> <complexType>
> <sequence>
> <element name="name" type="tns:Name"/>
> </sequence>
> </complexType>
> </element>
> ...
> <complexType name="Name">
> <sequence>
> <element name="first" type="xsd:string"/>
> <element name="last" type="xsd:string"/>
> </sequence>
> </complexType>
> ...
> - Next, I code-generated the static SDO types based on the updated WSDL file.
> I added the following to the root build.xml in order to generate the types
> (I wasn't able to find the necessary code-generator tools in the SCA
> distribution, so the following depends on an external SDO distribution
> specified by the environment variable TUSCANY_SDO. I used the
> tuscany-sdo-1.0-incubating-beta1 binary distribution for this test):
> ...
> <property environment="env"/>
> <target name="codegen" depends="init">
> <java classname="org.apache.tuscany.sdo.generate.XSD2JavaGenerator"

> - This produced the following files in src/main/java/helloworld:
> getGreetings.java
> getGreetingsResponse.java
> HelloworldFactory.java
> Name.java
> impl/getGreetingsImpl.java
> impl/getGreetingsResponseImpl.java
> impl/HelloworldFactoryImpl.java
> impl/NameImpl.java
> - Once these were in place, I modified HelloWorldService::getGreetings() to
> take the new Name type:
> ...
> public interface HelloWorldService {
> public String getGreetings(Name name); }
> - and modified HelloWorldServiceComponent::getGreeting() to match:
> ...
> public String getGreetings(Name name) {
> System.out.println("Called getGreetings");
> return helloWorldService.getGreetings(name);
> }
> - Finally, I modified HelloWorldServiceClient::main() to create a Name
> instance, and pass it into the getGreetings() call.
> ...
> Name name = HelloworldFactory.INSTANCE.createName();
> name.setFirst("David");
> name.setLast("Haney");
> String value = helloWorldService.getGreetings(name);
> ...
> - Once all of the code changes were in place, I went back to the
> src/main/resources/helloworldws.composite file, and attempted to update it so
> that it would recognize that it should be using the SDO binding:
> <dbsdo:import.sdo
> xmlns:dbsdo="http://tuscany.apache.org/xmlns/sca/databinding/sdo/1.0";
> factory="helloworld.HelloworldFactory"/>
> - That seemed like it should be sufficient based on the
> documentation/tests/demos/examples that I was able to find, however when I
> attempt to run the application, I'm seeing the following output:
> Buildfile: build.xml
> run:
> [java] log4j:WARN No appenders could be found for logger

> I've attempted this on Windows using the tuscany-sca-0.90-incubating binary
> distribution, as well as RC3 for the tuscany-sca-0.91-incubating
> distribution, and am seeing the same exception from both. The example is
> sending the data through a tcptunnel (so that I can see the on-the-wire
> format), and it appears this is failing while generating the message, since
> I'm not seeing any traffic on the wire.
