bean and exception

[Thierry]

Hello,
I want to manage that error : org.apache.jasper.JasperException: For input
string: "a"

I have a Bean with a method
public void setAge(int age) {
this.age = age;
}

I have a JSP
....
<jsp:useBean id="bean0" scope="session" class="test.Personne" />
<jsp:setProperty name="bean0" property="*" />
.....
Enter new value bean0.age : <input name="age">
the value is bean0.age is : <jsp:getProperty name="bean0" property="age" />
.....

I dont want to use javascript for validate my data
If I enter a letter in the aera and submit form
I have that error : org.apache.jasper.JasperException: For input string: "a"
How can I manage that exception ?

thank you

Thierry

Please don't multi-post, it is quite annoying.
Also, you'll need to post more of the exception you're getting. And when
does this happen? At runtime, or when the server tries to compile the jsp?
And does your bean have a getAge method?

Sorry for multipost
The problem happens when y submit the form
An I have a getAge method ?

<jsp:useBean id="bean0" scope="session" class="test.Personne" />
<jsp:setProperty name="bean0" property="*" />

I don't know how to catch that exception.

What I can contribute is that use of the wildcard version of
jsp:setProperty is universally considered to be a poor idea; even a
security risk if you're not very careful in separating trusted from
untrusted data in your application. I'd strongly recommend you look at
alternate ways of accomplishing this task, such as via Struts or JSF,
both of which provide convenient ways to parse input, fill in a bean,
and actually respond to validation or data conversion problems.
