sending null in Object Array

[Gal Rob <ga...@hotmail.com>]

Hi!
 
I'm sending Object[] to ws as one of the parameters. If Array members are Objects or primitive types everithing is OK. But if Object[] contains also nulls they will not get prop[agated to WS. Size of Array is decreased by number of null members in array. 
I'm quite new to WS so I'm not sure if this is part of JAX-WS specification or I'm doing something wrong.
 
Test code looks like this:
Object[] methodParameters = {"John", null};
NotificationService.sendNotify("TEST", methodParameters);
 
Thanks for help,
Robert

This is more or less per JAX-WS spec.   The mapping for an array 
parameter is just minOccurs=0/maxOccurs=unbounded.   It doesn't put 
nillable=true.

The ONLY way to control this is to generate a wrapper bean and modify the 
@XmlElement annotation to add the nillable=true thing.   You can use 
java2ws -wrapperbean to generate the initial versions.    Then add a 
@RequestWrapper annotation to your method to point at it.
