I am adding Axis 1.4 web services to a working Struts application.
In the Property class file auto-generated from WSDL, the references to java.util.Set are changed to java.lang.Object[].

Set rooms = property.getRooms();

generates error - Type mismatch: cannot convert from Object [] to Set;

Any suggestions or pointers to examples using Axis and Hibernate would be greatly appreciated.

First of all I'm not sure why your WSDL is producing a mapping to object[] instead of yourClass[] . Anyways, this is a matter of simple java ... I do stuff like this with Axis 1.x and more recently with Axis2 all the time:

Object [] objectArray = property.getRooms()
List objectList = Arrays.asList(objectArray);
Set arraySet = new HashSet (objectList);

There's your conversion. I suspect though that you'll either need generics to match the expected hibernate Set or put the object array in a for loop and populate it manually.

HTH,
