Tiles Integration with Struts 2 Annotation - struts2

Question

I have been trying to integrate Tiles with Struts 2 annotation based action but it's not working correctly.
As I don't have struts-config.xml and in every tutorial available at web they are referencing it with struts-config.xml.
First is it possible to integrate annotation based struts action with tiles. If yes then how?
#Action(value="/login",results={#Result(name="success",location="/home",type=TilesResult.class),
#Result(name="login",location="/jsp/userLogin.jsp")})
public String execute() {
This is what my code is but it always gives me error in MyEclipse at TilesResult.class that
Type mismatch: cannot convert from Class<TilesResult> to String
I have dependency in my pom:
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-tiles-plugin</artifactId>
<version>2.1.8</version>
</dependency>
Can anyone help me how to add tiles in annotation based actions
I used type="tiles" instead of type=TilesResult.class then it has given me below exception
Caused by: The Result type [tiles] which is defined in the Result annotation on the class [class com.actions.LoginAction] or determined by the file extension or is the default result type for the PackageConfig of the action, could not be found as a result-type defined for the Struts/XWork package [com.actions#convention-default#] - [unknown location]

Answer 1

Try these :
Use type="tiles" instead of type="TilesResult.class"
Use your target tile definition, location="tiles-definition-name", instead of JSP page, location="/jsp/userLogin.jsp", in your result location
Have following in your web.xml:
<context-param>
<param-name>org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name>
<param-value>/WEB-INF/tiles.xml</param-value>
</context-param>
<listener>
<listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
Have following in your struts.xml (If you are using annotations alone and no struts.xml, then you have to create a minimal one for this because there's no annotation available to define a custom result type)
<struts>
<constant name="struts.convention.default.parent.package" value="codeoftheday.blogspot.com"/>
<package name="codeoftheday.blogspot.com" extends="struts-default">
<result-types>
<result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" />
</result-types>
</package>
</struts>
NOTE: I've written a detailed blog post here on this issue - Maven, Struts2 Annotations and Tiles Integration Example via Convention / Codebehind / Zero Config plugin using Eclipse IDE

Answer 2

"org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG" this definition is not available with Strut 2.5.10.1
I have used following jars in my project.
struts2-core-2.5.10.1
struts2-convention-plugin-2.5.10.1
struts2-tiles-plugin-2.5.10.1
javax.servlet-api-3.0.1
Please once you compare your web.xml with following code.
