EntryPointNotFoundException using custom component
Hi all,
I have a service that uses a custom component. This component is a POJO with one method, that should receive the result of a custom transformer. Tha fact is I am receiving the following exception:
********************************************************************************

********************************************************************************
Reading the stacktrace, I see Mule is complaining that my component br.com.cit.pms.integration.VacationHistoryChangedListener does not have a method with a signature containing br.com.cit.support.humanresources.service.VacationHistoryChangedEvent, which is not true, since the component code is this:
import br.com.cit.support.humanresources.service.VacationHistoryChangedEvent
public class VacationHistoryChangedListener {
private String vacationProjectID;
public void setVacationProjectID(String vacationProjectID) {
this.vacationProjectID = vacationProjectID;
}
public ReallocateResourceRequest onVacationHistoryChanged(
VacationHistoryChangedEvent event) throws Exception {
....
return request;
}
}
I suppose mu config file is right, too:
<service name="pms.vacation_changed_history">
<inbound>
<jms:inbound-endpoint topic="Event.Support.HumanResources.VacationHistoryChanged">
<transformers>
<jms:jmsmessage-to-object-transformer/>
<custom-transformer class="br.com.cit.mule.XmlToJaxbObjectTransformer">
<spring:property name="jaxbObjectClass"
value="br.com.cit.support.humanresources.service.VacationHistoryChangedEvent" />
</custom-transformer>
</transformers>
</jms:inbound-endpoint>
</inbound>
<component>
<singleton-object class="br.com.cit.pms.integration.VacationHistoryChangedListener">
<property key="vacationProjectID" value="VACA01"/>
</singleton-object>
</component>
So, according to this scenario, why can't Mule find my beloved method???
Thanks!

Re: EntryPointNotFoundException using custom component
Are you sure that the message payload type is VacationHistoryChangedEvent when the transformers have been applied to your inbound JMS message? D.

Re: EntryPointNotFoundException using custom component
Oh yes, I am.
I forgot to mention, but I am logging on console the object returned by my transformer: VacationHistoryChangedEvent. Also note that the stack mentions it is trying to match this type of object.
I found out the problem! :-)
The problem was my component didn't have a setter method for the property. At least that was the change I made that eliminated the exception. I've read it somewhere and now I remember to try it.
It's a shame there is no clue in the stack that was the problem. I hope this thread can help other people...

Re: EntryPointNotFoundException using custom component
Ops... I meant I forgot the getter. In theory only the setter should matter, but the absence of the getter was causing the error.
