Question - Why do we overwrite the execute method and struts so as parts of the start framework?
Answer -
We can develop the action servlets and the action form servlets and other circuit classes in the action form class. We can develop a validated method that can return action errors object and in this method. We can write the validation code as well if this method returns null or action errors with the size of zero. The web container will call execute as part of the action class. If it returns a size greater than zero, it will call the execute method. It will rather execute the JSP servlet or the HTML file as the value for the input attribute is part of the attribute in the struts-config XML file.
