mule java component throwing IllegalArgumentException

Я запускаю Mule 3.6.2 в STS 3.6.4. Я пытаюсь использовать простой компонент Java.mule java component throwing IllegalArgumentException

public class MyComponent implements Callable { 

    public MyComponent() { 
    super(); 
    } 

    @Override 
    public Object onCall(MuleEventContext eventContext) throws Exception { 
    return eventContext.getMessage().getPayload(); 
    } 
}

и простой поток в фазе ввода Batch компонента ....

<flow name="MainFlow> 
    <http:inbound-endpoint exchange-pattern="request-response" host="${app.host}" port="${app.port}" path="test" doc:name="HTTP"/> 
    <cxf:jaxws-service serviceClass="example.sampleservice.TempService" doc:name="CXF"/> 
    <component class="com.temp.MyComponent" doc:name="Java"/> 
    <logger level="INFO" doc:name="Logger"/> 
</flow>

В Java компонент линии, я получаю

Я знаю, что такое средство исключения , но не в состоянии понять в этом контексте.

Не могли бы вы разместить полный стек? – jvas

Если вы хотите создать простой компонент java, то вместо реализации вызываемого, попробуйте с mule specific аннотации.

public myComponent(){ 
    super(); 
} 
public String myComponent(@payload String myPayload) { 
    <!--your operation goes here--> 
system.out.println("created my simple java component!"); 
return myPayload;

}

Ура!

Это будет работать, за исключением того, что мне нужен доступ к MuleEventContext :( – Jeet

Что вы хотите получить из eventcontext? –

@jeet вы можете использовать ** @ Groovy («eventContext») ** как один из параметров метода, чтобы выйти что-то из MuleEventContext. –
