Hi,
I guess the use of xsd:anyType is correct in case of a java collection being
used in return type or as one of the input parameters. However the first
issue which Borislav is facing is related to the generation of the
java.util.xsd.Map class. Even I have come across such issues and was not
able to get over them. I had to apply an XSL on the generated WSDL for
converting the java.util.xsd and java.util namespaces to xsd:anyType. This
way I was able to get over the issue as far as code generation was
concerned.
Secondly the Helper classes which were generated from the WSDL mapped the
xsd:anyType to be OMElement and hence in the Helper classes I had to write
my own code wherein I had to convert the OMElement to the Map during
de-serialization and Map to OMElement during serialization.
Regards
NIlesh

Subject: Re: java.util.Map and more specifically HashMap
Hi Borislav,
I am trying to understand the requirement. This is what I did,I just
include a method as yours in a pojo class and generated a wsdl from that
using the codegen tool. So as expectedly because you have used a collection
as the return type the wsdl include
<xs:element name="TestResponse">
<xs:complexType>
<xs:sequence>
<xs:element name="return" nillable="true"
type="xs:anyType" />
</xs:sequence>
</xs:complexType>
</xs:element>
anyType as element type of the return values, so what that means the output
from the web service can contain any kind of valid xml. So from this service
you can generate the skeleton and include your logic inside that skeleton to
create the service and deploy that. AFAIK since messages passes are in xml
you have to implement the logic to according to that inside service
skeleton.
Thanks
