downloaded tuscany 1.5.1 and stored in file system. created eclipse user lib to inlcude all the tuscany /lib jars

created a very simple hello world app and keep getting the same error

basically i have a client that launches the embedded tuscany web service

Quote:


import org.apache.tuscany.sca.host.embedded.SCADomain;


public class Launch
{

/**
* @param args
*/
public static void main(String[] args) throws Exception
{
System.out.println("Starting ...");
SCADomain scaDomain = SCADomain.newInstance("scaTest.composite");
System.out.println("wills test ready for big business !!!");
System.in.read();
System.out.println("Stopping ...");
scaDomain.close();
System.out.println();
}

}




I then have a simple interface class

Quote:


import org.osoa.sca.annotations.Service;

@Service (HelloWorldService.class)
public class HelloWorldImpl implements HelloWorldService
{
public HelloWorldImpl ()
{}

public String sayHello ()
{
return "hello William";
}
}



and a simple componnt that implements

Quote:


import org.osoa.sca.annotations.Remotable;

@Remotable
public interface HelloWorldService
{
String sayHello ();
}





lastly my composite file (tried various varitions on this and essentially net out to same error ) - tried service at top level and child withiun the component, one trying the sca:interface declarition, etc

current config looks like this

Quote:


<?xml version="1.0" encoding="UTF-8"?>
<sca:composite xmlns:sca="http://www.osoa.org/xmlns/sca/1.0" name="scaTest" targetNamespace="http://eclipse.org/scaTest/src/scaTest">
<sca:component name="HelloWorld">
<sca:implementation.java class="scaTest.HelloWorldImpl"/>
<sca:service name="HelloWorldService" promote="HelloWorld/HelloWorldService">
<sca:binding.ws uri="http://localhost:8085/HelloWorldService"/>
</sca:service>
</sca:component>
</sca:composite>



so why cant axis find my service - there appears to be no dispatching of the web service.

What did i do wrong ?

okay - think i've managed to sort myself (mostly ) out.

the web service was generated - and pointing my browser at it didnt do any good as it wasnt a soap message generated.

downloaded soapUI and point at the wsdl and i got the service work.

in passing is their an equivelent to @Local as opposed to @Remotable. That is if you want to build a reference to a local component - i got more errors until i added the @remotable to the referenced interface.

or do all sca interfaces have to be marked @remotable?

It seems, and I cannot believe it, that the SCA builder does not show an
error with such a composite.

You set the promote on a component service.
The right way to promote a service, is to declare it in the component,
declare another in the composite and make it promote the first one.

Here is one exemple of your composite with a correct promotion:

> <?xml version="1.0" encoding="UTF-8"?>
> <sca:composite xmlns:sca="http://www.osoa.org/xmlns/sca/1.0"
> name="scaTest" targetNamespace="http://eclipse.org/scaTest/src/scaTest">

> <sca:implementation.java class="scaTest.HelloWorldImpl" />
> <sca:service name="HelloWorldService">
> <sca:binding.ws uri="http://localhost:8085/HelloWorldService" />
> </sca:service>
> </sca:component>
> </sca:composite>

Once it is promoted, the service can be exposed correctly.

To check if a web service is correctly deployed with a Web browser, go
to the WSDL address. Generally <ws url>?wsdl

No.
Just those that can be invoked remotly.
