How to use ActionForm, ActionForward, DispatchAction, ActionMessages in Struts2 - struts2

I am converting application from struts1 to struts2 so I need to use ActionForm, ActionForward, DispatchAction, ActionMessages.
How I can use that in struts 2?

If you convert an app from struts1 to struts2 then you don't need to use these classes because they belong to struts1, but if you want to use struts2-struts1-plugin then you can use them. Note that using this plugin is is not easy and requires some effort to configure such application. See Struts 1 Plugin.

Struts 1 or Struts 2 . Which one is advisable for web application development?

I am little bit confused to choose Struts 1 or Struts 2 for my new web application development assignment. Could any one suggest me which framework should I use for development from architecture point of view? What are the points I should take care of to choose the struts version before I go for development of the application?
Any help will be appreciated.
Hi I prefer struts 2 because,
Struts 1.x
In struts 1.x front controller is ActionServlet
In struts 1.x we have RequestProcessor class
In struts 1.x we have multiple tag libraries like html, logic, bean..etc
In struts 1.x the configuration fine name can be [any name].xml and we used to place in web-inf folder
In struts 1.x we have form beans and Action classes separately
In struts 1.x an Action class is a single ton class, so Action class object is not a thread safe, as a programmer we need to make it as thread safe by applying synchronization
In struts 1.x we have only jsp as a view technology
Struts 2.X
In 2.x front controller is FilterDispatcher
In 2.x we have Interceptors instead RequestProcessor
In 2.x we do not have multiple libraries, instead we have single library which includes all tags
In 2.x the configuration file must be struts.xml only and this must be in classes folder
In 2.x form bean, Action classes are combinedly given as Action class only, of course we can take separately if we want
In 2.x an Action class object will be created for each request, so it is by default thread safe, so we no need to take care about safety issues here
In 2.x we have support of multiple view technologies like velocity, Freemarker, jasper reports, jsp.
Since you have mentioned that it is going to be a new web-application,Just go with Struts2.Struts1 has already in EOL which means there will be no loner support for the Struts1.
Also Struts2 is a new and very flexible framework and will provide you a lot more control.Here are
Choose latest version of Struts2 to start work with (2.3.15.1)
If you are planning to write your service layer in Spring, you can use Struts2-spring plugin to let spring DI manage struts2 component for you.
Since you seems new to Struts2, i suggest to pay special attention to OGNL which is a core building block in struts2 and you will going to use it a lot in your Tags at UI.
Struts2 has a very flexible plug-able architecture which let you to create as well use many plugin which can save your time to build functionality from start.
Hope this might help you.Additionally You can review and look in to other MVC framework also
I also prefer going with Struts2 itself rather than Struts1 because Struts1 is old and its EOL has been announced on September 1, 2013 with the message "the Struts 1.x web framework has reached its end of life and is no longer officially supported."
[Source:- wikipedia.org]
So it is better to go with Struts2[i have been using version:-2.3.1.1 as I faced some "Dispatcher error"(jar files in the package were not compatible with each other) issue while using 2.3.16 version]
Hope this might help.
I've had a similar dilemma as you do, but instead of going with Struts, I've chosen Tapestry after some consideration.
Some of its awesome features are
Pages as POJOs
Really good dependency injection
Scalable
Easy to learn with lots of examples
much more...

struts1 to struts2 migration message resource

Currently we are using Struts1 and we want to use struts2(convention+annotation) for incoming projects.
I'm having a problem with struts2 regarding message resource
in Struts1 we use a custom MessageResourceFactory which configured in struts-config.xml
<message-resource factory="" param="">
we used <bean:message> tags in struts1 to call the messages.
I can't find a good way to do it in struts2
any recommendation?
Never mind I ended up, overwriting the defaultTextProvider from Struts2 , define a bean for it in struts.xml and also set it as TextProvider that should be used.

How to integrate Struts2 with Thymeleaf?

Does anybody know how to integrate Struts2 with Thymeleaf? I could not find any tutorial regarding integrating Struts2 and Thymeleaf.
I wrote a simple plugin that supports using Thymeleaf templates as the result type for Struts2 actions. The readme file contains examples of how to use the plug-in. You'll need to build the plug-in from source, as its not currently in any Maven repositories.
