Re: How long are your struts-config files? Should I worry about performance?

[None None]

I'm still working on the conversion after two weeks.  It took me probably 
two days to identify all the changes that had to be made, and then about 5 
days of mostly search-and-replaces, and ever since then dealing with the 
unexpected problems during testing.  One of the tough parts was that this 
framework only allowed a single destination page mapped to an "action", and 
if the flow of your logic coming out of your actions (app controllers they 
were called in this thing), you actually had to throw a 
specially-constructed custom exception class that the controlling servlet 
would use to redirect.  Worse still, the destination was actually encoded 
into the exception, not simply defined in an XML file, so you had what would 
be in struts-config actually hardcoded in some places in the controllers!

And that was just the start of my misery! :)
I don't know if the app is any happier being on Struts, but *I* sure am! :)

None,
That was EXACTLY the kind of information I was looking for! Thanks for the
deatiled answer.
My god that homegrown framework must have been a beast to convert, but I 
bet
the app is sure happier now that its using Struts.

Best,
