Excellent! Thanks very much. Somehow -Eosv does not solve the problem.
So I put the nillable="true" in the element there, and it works.

this means your object structure do not have loaded the required fault
elements.
see you schema there should be an element named fault without
minOccurs=0 or nillable=ture.
So ADB gives an exception because of this.
if you want to remove this use -Eosv when genrating the code.
Amia.

Hi,
I created a web service code based on a wsdl, and it is run in resin
3.1.3, and I have the soapmonitor activated. When a web service
client
sent a soap message to it, it threw the following exception:

This exception will not be shown when all elements in the requesting
soap message are filled with non-empty (no-blankspace) values.
I notice that the exception is thrown from the following
axis2-generated
code:
public void serialize(final javax.xml.namespace.QName parentQName,
final org.apache.axiom.om.OMFactory factory,
org.apache.axis2.databinding.utils.writer.MTOMAwareXMLStreamWriter
xmlWriter)
throws javax.xml.stream.XMLStreamException,
org.apache.axis2.databinding.ADBException {
//We can safely assume an element has only one type associated
with it
if (localFault == null) {
throw new org.apache.axis2.databinding.ADBException(
"Property cannot be null!");
<======================== the line where the exception is thrown.
}
localFault.serialize(MY_QNAME, factory, xmlWriter);
}
My question is: In the line where the exception is thrown, why is the
parameter localFault null? How to make it as a non-null value?
Thanks.
