Re: NoSuchMethodError from binding-echo sample

Hi, Simon.

You must have imcompatible jars on the classpath. Can you rebuild the sca 
and distro and try again?

Thanks,
Raymond

Subject: NoSuchMethodError from binding-echo sample


I'm working on the binding-echo application sample and I'm getting the
following error from the binding-echo extension jar when I start the
sample application:

     [java] Exception in thread "main" java.lang.NoSuchMethodError:

org.apache.tuscany.sca.contribution.processor.StAXArtifactProcessorExtensionPoint
                             .addArtifactProcessor(Ljava/lang/Object;)V

     [java] Java Result: 1

Here's the failing code in EchoModuleActivator.java, including some 
println
calls that I added:

    public void start(ExtensionPointRegistry registry) {

        // Create the Echo model factory
        EchoBindingFactory echoFactory = new DefaultEchoBindingFactory();

        // Add the EchoProcessor extension
        StAXArtifactProcessorExtensionPoint processors = 
registry.getExtensionPoint(StAXArtifactProcessorExtensionPoint.class);
        EchoBindingProcessor echoBindingProcessor = new 
EchoBindingProcessor(echoFactory);
        System.out.println("processors: " + processors);
        System.out.println("processors class: " + 
processors.getClass().getName());
        System.out.println("echoBindingProcessor: " + 
echoBindingProcessor);
        System.out.println("echoBindingProcessor class: " + 
echoBindingProcessor.getClass().getName());
>>>>    processors.addArtifactProcessor(echoBindingProcessor);

Here's the output from the println calls.  It looks OK.

     [java] processors: 
[EMAIL PROTECTED]
     [java] processors class: 
org.apache.tuscany.sca.contribution.processor.DefaultStAXArtifactProcessorExtensionPoint
     [java] echoBindingProcessor: [EMAIL PROTECTED]
     [java] echoBindingProcessor class: echo.impl.EchoBindingProcessor

Any ideas what could be causing this NoSuchMethodError?
