Transferring Data from ValueObjects into DynaBeans

["Sumit S." <su...@virtusa.com>]

Hi,
   Is there a standard way of describing the DynaProperty array for creating a DynaBean into which I can populate data from a Value Object using PropertyUtils.copyProperties (...)

  For eg, when we are getting data from a resultset and use the ResultSetDynaClass

   BasicDynaClass bdc = new BasicDynaClass("foo", BasicDynaBean.class, rsdc.getDynaProperties());

 Is there a way to set the DynaProperties of the DynaBean when bringing the data over from a ValueObject (Say a struts based action form)

  What I have done as of now, is implemented a piece of code to introspect the ActionForm and create an array of DynaProperty objects that I am passing to the BasicDynaClass structure.

				propertyDescriptor = propertyDescriptors[i];		 
				propertyType = propertyDescriptor.getPropertyType();				
				propertyName = propertyDescriptor.getName();			
				dynaProperty = new DynaProperty(propertyName, propertyType);

Add all the dynaProperty Objects to an array and pass it to the constructor....

Is there another way ?
				

 
Thanks
Sumit

If you just want to copy the properties of your transfer object to set up a new
DynaClass, check out the WrapDynaBean class.

  MyValueObject mvo = ...;
  DynaBean dynabean = new WrapDynaBean(mvo);
