Re: IoC alone and annotations

I missed the final keyword in the code. indeed removing it allows the annotation to do its job. Thanks for the information regarding constructor Vs, field injection. I am very new to IoC and DI, so haven't yet come up with my own preference. Many thanks to everyone. Tim On 9 November 2011 01:05

Re: IoC alone and annotations

Hi, I've used T5-IoC outside of webapps many times...as Bob said, try it without the final (not that it would compile with...?) and ensure you're using the correct @Inject annotation: @org.apache.tapestry5.ioc.annotations.Inject public final Output o; public Hello() { System.out.println(o);

Re: IoC alone and annotations

It's (mostly) a matter of personal preference. I personally also like Constructor Injection better because it clearly establishes the dependencies required for the class in a single location. Also, if you use constructor injection, you can declare your fields final, whereas you can't do that for

Hi All, I have followed the instructions at [wiki Tapestry5HowToIocOnly] and got that working. However, is it possible to use annotations instead of passing the instance in the constructor? Thanks in advance, Tim
