[AXIS2] NumberFormatException on parsing null date with hot deployed RPC service

[Nicolae Marasoiu <nm...@kepler-rominfo.com>]

Hi;

In the auto-generated wsdl, I have such a type entry inside a
xs:complexType:
<xs:element name="createdDate" type="xs:dateTime" />

I get:
java.lang.NumberFormatException: badDateTime00
	at
org.apache.axis2.databinding.typemapping.SimpleTypeMapper.makeCalendar(Simpl
eTypeMapper.java:214)
	at
org.apache.axis2.databinding.typemapping.SimpleTypeMapper.getSimpleTypeObjec

	at
org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver.invokeBusinessLogic(
RPCInOnlyMessageReceiver.java:84)

How can I make axis generate nillable="true" on these elements also? Or is
it part of xs:dateTime definition?
The exception above is given precisely at asserting not null and not empty
value.
On the wire:
<modifiedDate xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
nil:nil="true" />.

Another problem I get with hot deployed RPC service is when I have null
array properties. For these nillable=true is generated in wsdl, but still:

The workaround I currently use is to make sure there are no null arrays, by
putting empty arrays instead.

Thenk you,
