Ok i try as you described but i get the following error whrn tuscany try to
examine the implementation tag:
GRAVE: Contribution Resolve Exception occured due to:

... 6 more
The sample client is like the java code written for CalculatorBinding example.
this is the composite declaration:
<component name="ProvaWSService">
<implementation.java class="it.netbureau.prova.ProvaWS"/>
<reference name="externalWSProvaWS">
<binding.ws
wsdlElement="http://prova.netbureau.it/#wsdl.port(provaWSService/provaWSPort)"
uri="http://localhost:8080/ProvaWS/provaWS"/>
</reference>
</component>
<component name="SampleClient">
<implementation.java class="calculator.CalculatorClientImpl"/>
<reference name="calculatorService"
target="CalculatorServiceComponent"/>
</component>
<component name="CalculatorServiceComponent">
<implementation.java class="calculator.CalculatorServiceImpl"/>
<reference name="ProvaWSService" target="ProvaWSService"/>
and the wsdl of jax-ws web services generated with Netbeans 6.7:
<?xml version="1.0" encoding="UTF-8"?><!-- Published by JAX-WS RI at

</definitions>
</component>
the reference was passed :
private ProvaWS ProvaWS;
@Reference
public void setCalculatorService(ProvaWS ProvaWS) {
this.ProvaWS = ProvaWS;
}
why can't get implementation class? I haven't the web service class relative to
port type definition in my classes packages but i have generated interface and
other java artifact with netbeans ws import (the web service is remote into
Tomcat 6.0.18 and tomcat was running)
anybody can help me, there is something wrong?
thank you very much
