Re: Validating user input
Hi, In my current project I'm using the gwt validation library (http:// sourceforge.net/projects/gwt-vl/) which supports both client- and server-side validation and integrates itself nicly with e.g. hibernate- validation ... Maybe it's something you're looking for. Kind regards, Lukasz On 7 Jan., 20:13, Dave ladjo...@gmail.com wrote: Hi, Could someone point me to some resources that shows how to validate user input.

Re: Validating user input
Hi Dave,
The JavaScript code sample for Number validation: for Client side validation
function isNumeric(obj, fieldName) {
var str = obj.value;
if ( ! isEmpty(obj, fieldName) ) {
if ( ! ValidateNumeric(obj.value) ) {
alert(fieldName + can have only numeric values.);
obj.value = ;
obj.focus();
return false;
}
else {
//obj.value = parseInt(str);
return true;
}
}
else {
return false;
}
return true;
}
function isEmpty(obj, fieldName) {
var str = obj.value;
if ( ! ValidateNotEmpty(str) ) {
alert(fieldName + is a mandatory field.);
obj.value = ;
obj.focus();
return true;
}
return false;
}
if ( ! isNumeric (document.formName.fieldName, 'FieldDisplayName') ) {
return false;
}
The Javat code sample for Number validation: for Server side validation
public static boolean isNumeric(String sTextString) {
boolean bResult = false;
Pattern p = Pattern.compile(^[0-9.]+$);
Matcher m = p.matcher(sTextString);
bResult = m.matches();
return bResult;
}
if ( ! ClassName.isNumeric(objBean.getFunctionId().trim()) ) {
objErrors.add(ActionErrors.GLOBAL_ERROR, new
ActionError(errors.database.error, Selected Function Name in Form Input
is Not Valid.));
}
