Re: Abstract Bean problem in Axis 1.2beta ['Watchdog': Virus checked] ['Watchdog': checked]
Patrick,
I dont think this is a bug.
Axis 1.1, need such configurations (as you have specified).
Axis 1.2 does not expects such configurations for array types. This is done
basically to conform WS-I BP 1.0 standard or profile.
Do one thing, Wrap array of MyBean1 into another class and define that
class in your type mapping. Iam sure it should work !.
cheers,

Please respond to
axis-user
If somebody is interested:
Somehow the problem was coming from the deployment configuration file
(deploy.wsdd) because I had (for some reasons) specified the type mapping
for the array of MyBean1 according to the following:
<typeMapping
xmlns:myNS="urn:myTest"
qname="myNS:ArrayOf_MyBean1"
type="java:MyBean1[]"
serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"
deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
Seems that Axis1.2beta doesn't work when these arrays mapping are
specified. Axis1.1 was working fine.
Anyway commenting out this type mapping did the trick.
If needed I can log that in the bug database (I have the complete server
source example with client ready).
Cheers,
Patrick.

Hi Kannan,
Thanks for the explanation ... it makes sense :)
I don't need to wrap the array of MyBean1 into another class because just removing the type mapping from the wsdd made it work.
Everything seems to be fine now.
So the conclusion might be that one has to let Axis do the type mapping for arrays of beans itself when deploying a webservice.
Maybe that was also true for Axis 1.1.
Cheers,
Patrick.
