Question

I am following this tutorial to create a SEO friendly url with struts2, however in my class

@RequestParameter
public void setId(int id) {
    this.id = id;
}

this error shows up on @RequestParameter

RequestParameter cannot be resolved to a type

I have included the struts2-core jara in my web-inf/lib but I am still wondering how come it is returning an error there.

Struts2 does not have any @RequestParameter in it…

By the way, you don’t need it at all to run your example.

Just remove it, compile and deploy 🙂

You may want to take a look at the Struts2 REST plugin too.

And searching a bit, it turns out that it is a custom Annotation created by the author of the blog post, with the only goal of helping his IDE, IntelliJ, to avoid highlighting the Setters as unused…

@StevenBenitez (that is a SO user too), you better remove your custom Annotation from the other examples in your blog, to avoid confusions on users who have not declared it nor read the blog post in which you describe it 🙂
