java.io.IOException: Non nillable element is null

It appears the solution to this is to re-generate the stubs (WSDL2Java) with
Axis 1.3. At least that appears to work for me.

Anand,
I, too, get this error. Did you ever find a solution to it?
Further, I don't believe I have access to the code that let's me control
the nillable attribute. The stubs I have don't have anything about
nillable, so that may be hiddent from me.
This is all part of a greater effort to upgrade to a WL 9 server. Been a
lot more trouble than I anticipated, first w XML parsing. Had to upgrade
from Axis 1.2 to get past the parsing problem. Axis 1.3 brings this
nillable problem.
Thanks!
Ronnie

I get the same error even when I populate the element with a genuine value.
I am at loss as to what is going on here. Please help.

When I populate the client side proxy object, I do not populate the
UserNameToken object, nor its parent, thus satisfying minOccurs = 0. I am
not setting the value to null. I am not sure what is going on here.

When the element is nillable=false then you are not able to set the value
to null. If you set nillable=true then regenerate the stubs you should
not get this error, but with the minOccurs=0 and nillable=true when you
set the value to null it will not send the placeholder.

Hi,
I have an issue here which is happening only in Axis 1.3 and not 1.1. I am
getting the following exception.
java.io.IOException: Non nillable element 'usernameToken' is null.

I have pasted the code fragment from the corresponding stub file auto
generated by Axis from the wsdl.
typeDesc.setXmlType(new
javax.xml.namespace.QName("http://schemas.xmlsoap.org/ws/2002/12/secext",
">>Security>UsernameToken"));
org.apache.axis.description.ElementDesc elemField = new
org.apache.axis.description.ElementDesc();
elemField.setFieldName("username");
elemField.setXmlName(new
javax.xml.namespace.QName("http://schemas.xmlsoap.org/ws/2002/12/secext",
"Username"));
elemField.setXmlType(new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"));
elemField.setMinOccurs(0);
elemField.setNillable(false);
typeDesc.addFieldDesc(elemField);
I tried changing nillable to true, but still have the same problem. Axis
seems to not handle minOccurs and nillable well. I am confused as to what I
can try here? This was not an issue with Axis 1.1
Please help.
