For starters, you should generally be using String properties in your form bean because this is what the JSP sends to you. If you declare an integer in your form bean, and the user enters character data into the text field, youre going to get an exception thrown before you (or the validator) ever gets to see it.
When you call BeanUtils.copyProperties(destObject, srcObject), it will do the type conversions for you. If the field names are the same, it will typically handle it. If youre using your own type that BeanUtils doesn't understand out of the box, you can register a class that implements the Converter interface. This tells copyProperties() how to convert it from a String. I do this quite a bit with enumerations. > -----Original Message----- > From: Caroline Jen [mailto:[EMAIL PROTECTED] > Sent: Saturday, June 17, 2006 10:48 PM > To: user@struts.apache.org > Subject: BeanUtils, Form Bean and POJO Bean > > The Java "types" of the properties in my form bean sometimes > are not the same as those of the data fields in my database. > > The request.getParameter(); always return a String.
