org.apache.commons.beanutils.PropertyUtil

[storck <di...@cms.tecmath.de>]

Hi,

I would like to use the PropertyUtil-class from
"org.apache.commons.beanutils" to copy the properties from one bean to
another.
For Example I have a bean bVO from type BBDetailVO and I have a bean bForm
from type ShowBlackBoardDetailsForm
If I do something like
	PropertyUtil.copyProperties(bVO, bForm);
I get an IllegalArgumentException and if I do something like
	PropertyUtil.copyProperties(bForm, bVO);
I get "NoSuchMethodException: Property 'pk' has no getter method"

Could you please HELP me !!!

If I use two normal beans mit 3 or 4 propeties and use the
PropertyUtil-class everything workes fine..

THANKS!!!!
