The reason I wanted to do this was to make my Action classes cleaner. I send a parameter to the Action to determine which item to pull from a database, then forward to a certain page.
I didn't think I could get the switch to work, it was worth a try though. For a situation like mine, what do you all find to be the best way of doing this? I know I can use a series of if statements, it's just not very pretty...

Not really, but for future reference I have found this resource to be more helpful for such questions:

The reason why it doesn't work is probably specific to the implementation of the language (maybe performance reasons), but a lot of people don't miss it -- nor would they agree, I suspect. The reason is that you can usually add behaviors to objects so that a single polymorphic method call can usually eliminate all of the infrastructural work of writing a switch statement, so doing a switch on an object doens't make much sense in that context. Of course, this is not applicable in all senses, such as your case with String which is final....
