Hi,
I have a webapp deployed in jboss and successfully deployed an aspect using the default aop deployer, this is the definition:
| <aop>
| <bind pointcut="execution(*core.services.document.DocumentService->*(..))">
| <interceptor class="core.services.aspect.DocumentInterceptor"/>
| </bind>
| </aop>
DocumentInterceptor implements org.jboss.aop.advice.Interceptor and tries to cast one of the parameters to its origin class like this:
DocumentServiceParameters parameter = (DocumentServiceParameters)(((MethodInvocation)invocation).getArguments()[0]);
|
this throws a ClassCastException, but if printed, getClass().getName() shows DocumentParameter as instance class and instanceof returns false if asked:
| 16:10:02,693 INFO [STDOUT] 16:10:02,692 INFO [CertificationService] Fin fullSignatureAndCertificateCheck
| 16:10:02,693 INFO [STDOUT] Instancia de parametros: core.services.document.DocumentServiceParameters at 1ad2db5
| 16:10:02,693 INFO [STDOUT] Is DocumentServiceParameters? false
| 16:10:02,694 INFO [STDOUT] 16:10:02,694 ERROR [SendDocWS] Error ejecutando servicio web Document
| java.lang.ClassCastException: core.services.document.DocumentServiceParameters
| at core.services.aspect.DocumentInterceptor.invoke(Unknown Source)
What's wrong here?, I can do reflection to get my DocumentServiceParameters methods invoked, but should be done the right way...
Is this some kind of classloading bug?
