displaying Date, BigDecimal as html:text

[kk...@firstenergycorp.com]

Hello,

I saw that <bean:write> has a "format" attribute for formatting dates and
dollar values. But I didn't see similar thing for <html:text>. If my bean
has a property called "amount" of type BigDecimal, and I want to display
that as a <html:text> for the user to modify the value, How can I format
it?

Also, if the user leaves the <html:text> field for BigDecimal as blank, I
get an exception (string->BigDecimal conversion exception). So, is the
solution to this is to make all formbean properties to be "String" type?


Thanks,
Kiran

You could do that, or you could have BeanUtils do it for you. However, 
as long as your form bean property is type BigDecimal rather than 
String, you will be unable to re-display erroneous inputs. In other 
words, if the user types in 'abc', you will not be able to retain that 
value and redisplay it for the user to correct unless you use String. 
That's why form properties should, generally, be String-valued.

you coud do something like
BigDecimal bigDecimalProperty;
public setBigDecimalProperty(String value)
{
try {
bigDecimalProperty = new BigDecimal(value);
}catch(Exception e) {
bigDecimalProperty = new BigDecimal(somedefaultval);
}
}
