If the DataHandler parameter is null, then the bean is instantiated with no data. NOTE: this may be useful if for some reason the DataHandler that is passed in throws IOExceptions when this method attempts to access its InputStream. It will allow the caller to retrieve a reference to the bean if it can be instantiated.
If the bean does NOT implement the CommandObject interface, this method will check if it implements the java.io.Externalizable interface. If it does, the bean's readExternal method will be called if an InputStream can be acquired from the DataHandler.
dh- The DataHandler that describes the data to be passed to the command.
loader- The ClassLoader to be used to instantiate the bean.
IOException- for failures reading data
ClassNotFoundException- if command object class can't be found
