There are solutions in Rails and Struts2 of course, but they are not clean where clean means not having to check against the value of the submit button with an if.

In Stripes, the name attribute of a submit button automatically calls the event handler method in the Action Bean with the same name. The value of the button, which is what the user sees, can be anything. So it's very clean and simple. In the JSP:

  <s:submit name="send" value="Press this to Send"/>
  <s:submit name="cancel" value="Press this to Cancel"/>

In the Action Bean:

  public Resolution send() {
    // user pressed Send button
    // do send action
    // return result
  }
  public Resolution cancel() {
    // user pressed Cancel button
    // do cancel action
    // return result
  }

Even better, using localized labels for the buttons is also very clean and simple. The Action Bean remains the same. In the JSP, you actually use less code:

  <s:submit name="send"/>
  <s:submit name="cancel"/>

You then put your localized labels in StripesResources.properties for the default locale and in StripesResources_xx.properties for other xx locales. For example:

StripesResources.properties:

  send=Press this to Send
  cancel=Press this to Cancel

StripesResources_fr.properties:

  send=Appuyez ici pour Envoyer
  cancel=Appuyez ici pour Annuler

Of course, you can use Unicode characters for the labels with the standard Java \unnnn notation.

Gotta love it!
