HI
If u can use struts Validator or not here this is not matter.
In Struts all in put text values takes Strings only. At the time of
populating Action Form use the class org.apache.struts.util.RequestUtils
class.
In Struts all input values are String type, see the following code how
to assign int variables.
int int_test;
this is u r declared integer variable in form so this is class level
variable is default value 0 at the time of running app in text field 0
will be displays.
<html:text property="testint" />
Out put:
<input type="text" name="testint" value="0">
in case u enter 'ABC' this field Struts populate like this
names = request.getParameterNames();
try{
while (names.hasMoreElements()) {
String name = (String) names.nextElement();
.
.
.
}
}catch(Exc e){
}
in case any Exception raised it d't assign input value so the default
value int_test=0 as it is
- I just add "if myInteger < 1 " in method
validate().
Ok its works fine
If I define myInteger as String - how do I check that it's a valid
number in the validate() method (without using Validator)?
Private void setMyInteger(String s){
Try{
This.Int_test_my_validation=Integer.parseInt(s);
}catch(NumberFormatException nfe){
}
in case int declared form
Private void setInt_test(int i){
This.int_test=i; //if input value is 'ABC' int_test=0 assigned
}
U no need wary about that validation that is done automatically Struts
in case u declared as int.

Hi again
When you say that validation doesn't work when inserting "ABC" in an
integer field - do you mean when using struts Validator?
I'm not using the Validator - I just add "if myInteger < 1 " in method
validate().
If I define myInteger as String - how do I check that it's a valid
number in the validate() method (without using Validator)?
Thanks
Rivka
