Hi John,

The code you posted in example #1 is a Struts Action definition. The code in example #2 links to a Struts Action and passes parameters to it. In both cases, the code has to do with presentational logic, not J2EE back-end logic. If you want to understand code like this, I would suggest buying a Struts book. J2EE is more about what happens further down the callstack from the execute() method.
