Apache Tuscany y Spring

Sigo experimentando con Apache Tuscany, hoy el objetivo es hacer un ejemplo con integración con spring. Mismo ejemplo que hicimos en : http://emanuelpeg.blogspot.com/2010/05/desarrollar-un-ejemplo-con-apache.html

Comenzamos escribiendo la interfaz:

@Remotable
public interface ExampleService {

String sayHello();

}

Su implementación :

@Service(ExampleService.class)
public class ExampleServiceImpl implements
ExampleService {

private String hello = "Holasss !!! \n";

public void setHello(String hello) {
this.hello = hello;
}

/**
* @see org.assembly.nornas.ExampleService#sayHello()
*/
@Override
public String sayHello() {
System.out.print("llamaron a Say");
return hello;
}

@Init
public void init() {
System.out.println("Starting with "+ExampleServiceImpl.class + " \n");
}

}

Ahora tenemos que configurar el beans de spring, en un archivo que llamaremos: appcontext-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:sca="http://www.springframework.org/schema/sca"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/sca http://www.osoa.org/xmlns/sca/1.0/spring-sca.xsd ">


<bean id="service.example" class="com.elpaquete.ExampleServiceImpl">
<property name="hello" value="Hola desde Spring!!" ></property>
</bean>


<sca:service name="ExampleService"
type="org.assembly.nornas.sandbox.service.example.ExampleService" target="service.example" />


</beans>

Notaron que además de declarar el bean le indicamos a Apache Tuscany cual es la interfaz de nuestro bean que va a ser un componente de Apache Tuscany.

Ahora escribimos el archivo ExampleSpring.composite:

<?xml version="1.0" encoding="UTF-8" ?>

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
xmlns:t="http://tuscany.apache.org/xmlns/sca/1.0"
targetNamespace="http://nornas"
xmlns:nornas="http://nornas"
name="Example" >

<component name="ExampleServiceComponent">
<implementation.spring location="spring-sandbox.xml" />

<service name="ExampleService">
<interface.java interface="org.assembly.nornas.sandbox.service.example.ExampleService"/>
<binding.ws uri="http://localhost:8080/nornas/ws" />
<t:binding.atom uri="http://localhost:8080/nornas/atom" />
<t:binding.jsonrpc uri="http://localhost:8080/nornas/jsonrpc" />
<t:binding.rss uri = "http://localhost:8080/nornas/rss"/>
<binding.sca />
</service>

</component>


</composite>

Notaron que la implementación del componente no se indica clase si no el archivo appcontext-spring.xml, Apache tuscany va a leer y buscar de ahí la implementación.

Ya lo tenemos, ahora vamos a hacer la clase main:

public class MainSpring {

public static void main(String[] args) throws IOException {

System.out.println("Starting ...");
SCADomain scaDomain = SCADomain.newInstance("ExampleSpring.composite");
System.out.println("Example in "+scaDomain.getURI());
System.in.read();
System.out.println("Stopping ...");
scaDomain.close();
System.out.println();

}

}

Si todo salio bien, en http://localhost:8080/nornas/ws?wsdl va a estar wsdl de su web service soap.
