HI ,
a dto is a user defined class inmy case its a simple bean with getter and setter methods . So how can a array of such a class be returned .
I am getting the follwing error :


Listing current CD catalog.
[SOAPException: faultCode=SOAP-ENV:Client; msg=No mapping found for 'urn:St
udentService:Student' using encoding style 'http://schemas.xmlsoap.org
/soap/encoding/'.; targetException=java.lang.IllegalArgumentException: No m

I had to Google it too, but then of course it hits you...it's one of the good ol' Core J2EE Patterns. I always think of them as 'transfer objects' or 'value objects'.

In any case, to send a DTO, you need to generate some classes to do the Java <-> XML mapping. Looks like you're using Axis, so wsdl2java would be the natural choice.
