[jboss-user] [JBossWS] - Re: Newbee Q: Returning hashmaps

  | Most probably, wsconsume generated a class named HashMap, instead of using java.util.HashMap. This class is not actually a hashmap but a representation of the web service return data. Most probably, you'll need to convert that data to an actual hashmap.

  | I notice you commented out the cast to java.util.HashMap, probably you got a ClassCastException here? Seeing the class generated by wsconsume and related wsdl would help.

  | Your web.xml file should not be the problem. It just exposes the webservice, and since you're able to invoke it, it is doing its job.

Thanks mikkus. Yes, wsconsume creates it's own HashMap which inherits from it's own AbstractMap. 

How do I convert the wsconsume generated HashMap to java.util.HashMap? I believe this needs to be done at the client side.
