doValidation

protected void doValidation()
Description copied from class: ActionSupport
Subclasses may override this method to provide validation of input data. The execute() method should call validate() in the beginning of its code (which will delegate to this method), so as to check input data before doing the actual processing.

If any application errors arise these should be registered by calling addErrorMessage or addError .

If the validation is dependent on whether a command has been issued, and what that command is, then the isCommand() method should be used.

Overrides:
doValidation in class ActionSupport

doExecute

protected java.lang.String doExecute()
Overrides:
doExecute in class ActionSupport
