Hi Venkatesh,

Thanks. I have corrected the problem but now I am getting this error:

Error : org.xml.sax.SAXException: No deserializer for {urn:PublicService3}Param.

As you see in the Client code and the deploy.wsdd I have defined deser. I don't know what is going on.

Thanks,

Tony.

Hi Tony,
There is a problem with your client code.. You have sent the
return type as Param and your type casting the result to a ArrayList..
So, modify your Client.java file and you need to modify the statement
call.setReturnClass(Param.class)...

regards
Venkatesh
