Tiles Integration with Struts 2 Annotation

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]

Did you try with `type="tiles"`? Also you'll need to make sure your parent package extend the tiles default. — Dave Newton, Jul 21 '13 at 01:19
Yes I did but after that it has given me following exception: Post Updated — Wasif Kirmani, Jul 21 '13 at 08:30
Make sure you have codebehind plugin included with the deployment. — Roman C, Jul 21 '13 at 09:06
@WasifKirmani http://struts.apache.org/release/2.3.x/docs/codebehind-plugin.html — Roman C, Jul 21 '13 at 09:23
@RomanC I am not using this plugin it's deprecated too... so I am just trying to integrate tiles with my struts 2 but without xml gluecode i.e. struts.xml and stuff.. — Wasif Kirmani, Jul 21 '13 at 09:48
@WasifKirmani Really, what is the code from your question, clarify and update it. Because your annotation looks like codebehind based. — Roman C, Jul 21 '13 at 09:53
@RomanC it was simply struts2 with tiles integration but using annotation not struts.xml. So, in this case I am not completely sure about the result-type annotation. Because in struts.xml we must need to define something like 08. 09. but, here in my case i don't want struts.xml so how to achieve it this is my main questio — Wasif Kirmani, Jul 21 '13 at 10:02
@WasifKirmani Incorrect usage of annotations, I didn't see that is a one of the major problem in your question and not codebehind related, anyway your version is outdated. — Roman C, Jul 21 '13 at 10:14
@RomanC which version do i need to use then?? as my struts library is 2.1.8 — Wasif Kirmani, Jul 21 '13 at 10:32
@WasifKirmani Exactly, this version of struts library and plugin. — Roman C, Jul 21 '13 at 10:34
So in my case both are same... 2.1.8 org.apache.struts struts2-tiles-plugin 2.1.8 org.apache.struts struts2-core 2.1.8 — Wasif Kirmani, Jul 21 '13 at 10:35
Your action needs to be in a package that extends the tiles package, as I said. — Dave Newton, Jul 21 '13 at 11:58
@DaveNewton But this is the confusion I don't have any struts.xml file as using annotations. So, how can I extend my package with tiles package using annotation?? — Wasif Kirmani, Jul 21 '13 at 13:58
By reading the docs and using the appropriate parent package. — Dave Newton, Jul 21 '13 at 15:54

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

Basically I am using annotation with tiles and it's giving me another exception i have done that too SEVERE: Exception starting filter struts2 Unable to load configuration. - [unknown location] — Wasif Kirmani, Jul 21 '13 at 15:15
@Syed Muhammad Humayun Is Struts 2.5.10.1 support annotation for result-type tag or any other alternative ? — deepaksingh pawar, Jun 17 '17 at 10:27

"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.

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    <init-param>

        <param-value>com.demo.action</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
