Your question is far too vague. ActionFrom is a Struts1 type;
interceptors are a Struts2 concept; saying 'I have validations' or 'I am
using interceptors' tells us nothing about how you have these configured.
Since you seem to be struggling with integrating S1 and S2 in the same
app, I suggest you go back to basics and create a minimal, empty app
using S1 and S2 together and use it as a starting point to explore each
issue you find in isolation. That way you can post complete but concise
examples of code and configuration that demonstrate the problem.

Are you billing by the hour for this?
Seriously, have you seen the last three times where I said that in order to
help we need to see the complete configuration and code necessary to
duplicate the problem? Can you post that on pastebin.com?

Yes ...
I have replaced <html:rewrite> with normal href ...
I am able to view Login.jsp. But when I click on submit ...it throws me out.
Please let me know at your earliest possible

So you're using the S1 Plugin, correct?
Do you understand you will have to re-write all your JSPs to use Struts 2
tags?

You need to send a text-format message (not HTML) with your configuration
file or use a service like pastebin.com, as I said before. The latter is
preferable; it's nicely highlighted and you can paste all of the relevant
code and configs.

Let me be clear then ...
I am trying to migrate from struts1.2 to struts2.
I did all the required configuration. I could get the login page.
LoginActionForm is extending ValidatorActionForm. I defined an interceptor
for it in struts.xml. Validation is form based.
BUT when I enter username and password and click submit... it throws me this
error :
[Servlet Error]-[org.apache.struts.action.ActionForm]:
java.lang.InstantiationException: org.apache.struts.action.ActionForm
at java.lang.Class.newInstanceImpl(Native Method)
at java.lang.Class.newInstance(Class.java:1263)
at com.opensymphony.xwork2.ObjectFactory.buildBean(ObjectFactory.java:123)
at com.opensymphony.xwork2.ObjectFactory.buildBean(ObjectFactory.java:154)
.....
I have the required jars.... Please let me know how I can take care about
the validations during migration.
Thanks,

What were you doing before?
Please note: your configuration files aren't getting to everybody properly
(me, at least), so it's even more difficult to help. Consider configuring
your email client to send text-only messages to the list or using a service
such as pastebin.com. Thanks :)

I'm not sure what all I'm not seeing here, so I can't really comment.

I would assume that an interceptor-stack can have the same name as an
interceptor-ref, but as a matter of style I wouldn't do it; because it's
confusing.

Again, not sure what all we're missing.
Just to be perfectly clear: you are attempting to use the S1 Plugin, so that
your existing S1 actions etc. will be configured only in the Struts *2*
configuration file (there will be *no* Struts 1 configuration file)?
Note: According to the S1 Plugin documentation [1] you *cannot* use the S1
tags in your JSP pages, meaning you are forcing yourself to JSP rewrites.
(The other option is running the two apps more or less indepedently, but
still in the same webapp: no JSP rewrites, no plugin issues.)
Sometimes it's easier to introduce a new framework and any associated costs
(training, learning curve, etc.) on a greenfield project rather than attempt
to shoehorn it into an existing ecosystem.

Hi,
Now I am migrating from struts1 to struts2.
In struts1 I have a homeAction which extends dispatchAction and it uses
homeActionForm.
I have configured it this way in struts.xml:
<interceptors>
<interceptor name="homeActionForm"
class="com.opensymphony.xwork2.interceptor.ScopedModelDrivenInterceptor">
com.XXX.XXX.HomeActionForm
homeActionForm
</interceptor>
<interceptor name="homePage"
class="org.apache.struts2.s1.ActionFormValidationInterceptor">
/org/apache/struts/validator/validator-rules.xml,
/WEB-INF/validation-rules.xml, /WEB-INF/Validation.xml
</interceptor>
<interceptor-stack name="homeActionForm">
<interceptor-ref name="staticParams" />
<interceptor-ref name="homeActionForm" />
<interceptor-ref name="modelDriven" />
<interceptor-ref name="actionForm-reset" />
<interceptor-ref name="basicStack" />
<interceptor-ref name="homePage" />
<interceptor-ref name="workflow" />
</interceptor-stack>
</interceptors>
<action name="loadPage"
class="org.apache.struts2.s1.Struts1Action">
com.XXX.XXX.homeAction
<result name="load" type="tiles">/home.jsp</result>
</action>
