I'm trying to implement the Struts 2 Annotations in my project, but I don't know how.

I added the convention-plugin to my pom

I modified the web.xml like this:

But when I add the @Result annotation, the IDE tells me:

What I'm doing wrong?

Using a "value" annotation parameter, of which there isn't one. Do you mean "location"?

See the Result annotation documentation.

The first time I tried with location and it didn't work and I saw "value" in a Struts 2 book (??) and I thought this is the reason why is not working.

Anw, I retried the same setup and doesn't work. When I press the link associated to the action helloWorld (I have a class HelloWorld which extends ActionSupport, its sends me to the exactly the same page. So, from index.jsp, it's sends to index.jsp.

I uploaded the project (a simple HelloWorld app) to FileFront, maybe someone sees where is the problem.

And what's the problem? That doesn't look like what you had posted originally.

Note that Action.SUCCESS is *not* "SUCCESS", but rather "success".

Ok. I changed that. Anw, I don't see any difference for the moment. :)

I commented the package section from struts.xml and now I receive:
# Messages:
There is no Action mapped for namespace / and action name helloWorld.

So

If in my struts.xml I have this code:

I get the behaviour from the 3rd post.

So, from index.jsp, it's sends back to index.jsp. It should send me to HelloWorld.jsp

If I comment the package section I receive

There is no Action mapped for namespace / and action name helloWorld.

Turn up the log level to DEBUG and check out how it's scanning: you'll find there are a couple of issues.

You can also use the config-browser to help track stuff like this down--it will tell you what S2 believes your configuration to be (including convention-based actions). Read the convention plugin documentation page very carefully, paying attention in particular to the parameters it provides, and their defaults. It is not always doing what I think you believe it is.

Also, be cautious about using package names that aren't yours.
