RE: BeanUtils and Dates

[Greg Dunn]

robert:

Thanks for the assistance.  As it happens storing the value as a Timestamp
suits my purposes and it works with "off the shelf" BeanUtils.  However I'm
sure your solution will come in handy with other nonstandard data I need to
deal with.

hi greg

the standard SqlDateConvertor in beanutils uses java.sql.Date.valueOf to
perform the conversion. this method requires a date in sql date format ie
yyyy-mm-dd. i don't think that the conversion will work given an input in
your format.

there is an easy way to make this work in beanutils. you can create a
custom converter and then register it to handle your java.sql.date's.

i'd create a custom convertor by extending SqlDateConverter and overriding
convert with something like

<untested-code-warning>

public Object convert(Class type, Object value) {

        if (value == null) {
                return super.convert(type, value);
        }

        return super.convert(type, value.toString().substring(0, 10));

}

</untested-code-warning>

see java docs for explanation of how to register a custom converter.
