problem in Beanutils.copyProperties()

[Rahul]

Hi all,

I am having a problem in using copyProperties() of
org.apache.commons.beanutils.BeanUtils class

I am doing it in this way

BeanUtils.copyProperties(destBean,srcBean)

where destBean and srcBean both have a property by name date,

which is of type java.sql.Timestamp()

If date property of srcBean is set to null then the above statement
gives

an exception: "BeanUtil.ConversionException: No value specified"

It works fine in case srcBean.date is properly initialized.

But there is a possibility of having null in srcBean.date in my code.

So, how to deal with this?

You would do a read of the field and a set.

My reaction is that is a very dangerous way to copy a single field.
You could inadvertently copy other fields as well that just happened
to have the same name.
