> I'm using the Betfair API and Axis 2 in ADB mode, and have discovered that RuntimeExceptions
are being thrown when perhaps they shouldn't. The offending XML is:
> <runners xsi:type="n2:ArrayOfRunner" /> 
> I'm pretty sure this violates the WSDL spec -  instead it should be the following:
> <runners xsi:type="n2:ArrayOfRunner" xsi:nil="1"/>
> The relevant bit from the Betfair WSDL is this:
> <xsd:element name="runners" nillable="true" type="types:ArrayOfRunner" /> 
> I've traced through the ADB-generated code and it leads to a RuntimeException if the
tag is empty but xsi:nil="1" is not present. Is this against the design spec for Axis? I was
previously using Axis in XMLBeans mode, which I believe is more lenient in handling issues
like this. XMLBeans also does not mind if boolean values are set to "true" or "1", whereas
ADB only works when boolean values are set to "true" - this also might be against the spec.
> The main issue is that whenever a RuntimeException is thrown, it basically causes some
part of Axis to completely hang, meaning that no further calls to the Betfair API from the
same thread can be made, even though I am catching the RuntimeException. This surely isn't
intended in the Axis 2 design? 
> Betfair will probably issue a fix for this eventually, but it's a very serious issue
and I can't think of an easy workaround at the moment (apart from going back to XMLBeans code!)
