Your action mapping has class="mainpage", but your Spring configuration
has id="mainpageAction". These should be the same. I'm not quite sure
how you're getting the error you are, though, based on that
configuration. And I don't see how introducing an @Result annotation
would effect it. I suspect you have some out-of-date config files
deployed or something, since the error is inconsistent with what you
show here.
Try doing a clean build/deploy and check that the deployed configuration
is what you think it is. One other point to check: do you have the
struts2-spring plugin deployed? You need that to allow your actions to
be managed by Spring.

Every thing works perfectly if I do not use annotations but use configuration
xml files.
My annotation part is as follows:
@Result(
name="success",
value="mainpage.page",
type=TilesResult.class)
I use the following configuration in an xml file and it works:
<package name="mainpage" namespace="/" extends="tiles-default">
<action name="mainpage" class="mainpage">
<result name="success" type="tiles">mainpage.page</result>
</action>
<!-- Add actions here -->
</package>
Using annotations I have error message (look below)
From the error message I think that Struts is trying to create my Action
object and it fails because I do not have a default constructor.
It could be the case, thought, that Spring managed to successfully create
the object but I do not refer to it the right way.
In my applicationContext.xml I have:
<bean id="mainpageAction"
class="com.gbsoft.belfin.communitypages.actions.mainpage.MainpageAction"
autowire="autodetect"
singleton="false">
<constructor-arg>
<value>Buenos Dias!</value>
</constructor-arg>
</bean>
Does my id have the right value (id=”mainpageAction”)?
