Hi Frank,
The problem is that the Tuscany runtime does not seem to create a DataObject of
the expected type.
The service implementation code looks like this
public DataObject getGreetings(DataObject getGreetings)
{
System.out.println("type of submitted DataObject is: {" +
getGreetings.getType().getURI() + "}"
+ getGreetings.getType().getName());
return null;
}
The output on the console I get is: type of submitted DataObject is:
{http://www.apache.org/tuscany/2005/SDO}AnyTypeDataObject
However, I would expect Tuscany to create a DataObject having type
{http://helloworld/type}GetGreetings which I would expect Tuscany to derive
from the XML Schema referenced in the WSDL used to describe the service.
My helloworld.composite looks like this:
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
targetNamespace="http://sample";
xmlns:sample="http://sample";
xmlns:dbsdo="http://tuscany.apache.org/xmlns/sca/databinding/sdo/1.0";
xmlns:wsdli="http://www.w3.org/2004/08/wsdl-instance";
name="helloworldws">
<service name="HelloWorld" promote="HelloWorldImpl">
<interface.java interface="helloworld.HelloWorld" />
<binding.ws
wsdlElement="http://helloworld#wsdl.binding(HelloWorldSoapBinding)"
wsdli:wsdlLocation="http://helloworld wsdl/helloworld.wsdl" />
</service>
<component name="HelloWorldImpl">
<implementation.java class="helloworld.HelloWorldImpl" />
</component>
</composite>
However, it seems that Tuscany couldn't care less about my WSDl and Schema. Am
I getting something wrong here? How do I declare the WSDL and Schema so that
Tuscany considers it?
Kai

Hi Kai,
Dynamic DataObjects should have dynamic types. I'm not sure I understand
exactly what is happening in your example, but DataObject.getType() should
be returning the appropriate types. If it isn't then my guess is that the
metadata wasn't registered/initialized properly.
Frank.
