    @Startup and Seam interceptor

    Xinhua Gu Newbie

      Hi everybody,

      it seems that Seam interceptor doesnot work with @Startup.
      I have an app scope Seam Component loaded by deployment, in this Seam Component i use my own annotaion (which used seam interceptor) to inject jndi resource, but it does not work.

      please help

      many thanks in advance

          Does your interceptor work with other Seam components that are not annotated with @Startup? Please post your annotation and interceptor code.

            hi,
            yes, interceptor works fine with other component without @Startup

            At first, i have two annotations

            @Target(TYPE)
            @Documented
            @Retention(RUNTIME)
            @Interceptors(KleberInterceptor.class)
            public @interface Kleber
            {
            
            }
            




            interceptor is supposed to check filed with @Jndi annotation and take the string from @jndi for jndi lookup
            public class KleberInterceptor {
            
             @PostConstruct
             public Object jndiLookup(InvocationContext invocation )throws Exception{
             Object target = invocation.getTarget();
             Field[] fields = target.getClass().getDeclaredFields();
            
             try{
             InitialContext ctx = new InitialContext();
             for(Field field: fields){
             Jndi jndi = field.getAnnotation(Jndi.class);
             if(jndi!=null){
             Object obj = ctx.lookup(jndi.value());
             field.setAccessible(true);
             field.set(target, obj);
             }
             }
            
             }catch(Exception ex){
             ex.printStackTrace();
             }
            
             return invocation.proceed();
             }
            
             @AroundInvoke
             otherMethods............
            
            
            }
            


            I can not use @Kleber on a component which already has a @Startup, what i can do now ,is to write jndi lookup codes directly in @Startup component, and it works.....

            is there any better way to inject jndi resouce in @Startup Seam component?

              So how does it not work? Does the interceptor run? Does it run and not set the values?

                nothing happened. @Startup is ignored also. Interceptor does not run.

                i put a @Create in this @Startup seam component, if my annotation @Kleber is there, @Create function doesnt run, the compoent wont be created by deployment.

                I donot know how to debug a @Startup Seam component :(
