[JBoss Seam] - Trying to get an interceptor working. Please help
by gbc＠gmx.de
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:

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,
