Trying to get an interceptor working. Please help
Hello everyone,
seems that I have no luck getting an interceptor working. My Interceptor method is called but does always throw an exeption (java.lang.IllegalAccessException) when the invocation should be proceeded.
My interceptor:
import javax.interceptor.AroundInvoke;
import javax.interceptor.InvocationContext;
import org.jboss.seam.annotations.intercept.Interceptor;
@Interceptor
public class PropertyInterceptor {
@AroundInvoke
public Object injectProperty(InvocationContext inv) {
try {
String methodName = inv.getMethod().getName();
System.out.println("injectProperty(): called: methodName: " + methodName);
return inv.proceed();
} catch (Exception e) {
System.out.println("inv.proceed exception:");
e.printStackTrace();
return null;
}
}
}
My Annotation:
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import org.jboss.seam.annotations.intercept.Interceptors;
@Interceptors(PropertyInterceptor.class)
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface Properties {
}
My SessionBean that should be intercepted
import javax.ejb.Stateless;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.faces.FacesMessages;
import org.jboss.seam.log.Log;
@Stateless
@Name("interceptorAction")
@Properties
class InterceptorAction implements InterceptorActionLocal {
@Logger
Log log;
@In
FacesMessages facesMessages;
public void useProperty() {
log.info("useParameter(): called:");
facesMessages.add("useParameter(): called");
}
}
Called from a facelet (like generated by seam-gen) with #{interceptorAction.useProperty()} gives following exception
10:28:45,703 INFO [STDOUT] injectProperty(): called: methodName: useProperty 10:28:45,703 INFO [STDOUT] inv.proceed exception: 10:28:45,703 ERROR [STDERR] java.lang.IllegalAccessException: Class

I'm using JBoss 4.2.0 GA and Seam 2.0 Beta1.
Could you please give me a hint what I missed?
Thank you very much,
