Struts2 ActionSupport strange issue, without extending it, works fine. please explain the concept

After clicking Submit in Login.jsp page, Action is not calling IFFFF I extends ActionSupport.
If I remove the extends ActionSupport, it is working fine, it is calling execute method.

Please explain why it is happening like this ???

Struts action config:

Login.jsp:

Struts action class:

LoginInfo.java

Tiles:

All actions may implement this interface, which exposes the execute() method.

However, as of XWork 1.1, this is not required and is only here to assist users. You are free to create POJOs that honor the same contract defined by this interface without actually implementing the interface.

I'm not sure how the Action documentation is relevant.

In any case, I'd guess it's a validation issue, but you don't provide enough information to help.

I'm confused. I thought it was basically the same question as this post. i.e. "why does it work if I don't extend ActionSupport?". I see now he's saying it doesn't work if he DOES extend ActionSupport.

Ah, gotcha.

I do not have any validation code in my jsp/action class. Please let me know what information I need to provide.
I am very much confused. I tried by putting @Override after extending ActionSupport on execute method. No results

@Override is a development tool to make sure you've actually overridden a method--nothing more.

Do you have validation XML config for the action? Have you set logging to DEBUG level to see if it's going through the validation stack (or if something else funky is happening)? Are you using the default interceptor stack?

I'd still guess it's a validation issue.

Yes David, your guess is correct

Actually there was a Login-validation.xml file which I created long back. I forgot about that. Just now only I saw as per your comments.
This solved my problem

Thanks a lot David

Glad to hear you figured it out--those validation files can cause problems if we forget about them!
