newbye. setProperty exception bad format. how to handle ?

[dpr]

I use a setProperty with property="*" in a start of my jsp.

But I happen to have a property that is supposed to be an integer which
get initialised with bad data (alphabetic char).

To be clearer:

<jsp:useBean name="mybean" property="*" />

mybean have a property of type int named myProp and the page gets call
with a parameter myProp="abcdef"

This results in a exception displayed in the web browser.

I know I could encapsulate the useBean in a try catch block, or use a
string (instead of an int) and validate it myself.

But what is the usual way to handle this (if there is one) ?

Thanks in advance.
