Instantiation Exception
Hi
I'm having a little trouble using SOAP
What happens is this:-
The Call generated a Fault:
Fault Code = SOAP-ENV:Server.BadTargetObjectURI
Fault String = Unable to resolve target object:
com.datalex.has.travelservices.xmlservices.XMLHotelService
Fault Actor = /soap/servlet/rpcrouter
[Attributes={}] [faultCode=SOAP-ENV:Server.BadTargetObjectURI]
[faultString=Unable to resolve target
object: com.datalex.has.travelservices.xmlservices.XMLHotelService]
[faultActorURI=/soap/servlet/rpc
router] [DetailEntries=[(0)=<stackTrace>java.lang.InstantiationException:
com.datalex.has.travelservices.xmlservices.XMLHotelService
at java.lang.Class.newInstance0(Native Method)
at java.lang.Class.newInstance(Unknown Source)

] [FaultEntries=]
my XMLHotelService accepts two parameters in it's constructor. However if I
create an empty constructor everything works fine (to an extent), but this
is not what I want.
Anyone know why it doesn't seem to like a constructor with parameters?
thanks

Apparently the problem here is that you want to pass in arguments to the
constructor which is not possible in SOAP. The question is if this is something
specific to Apache SOAP or is it something in the SOAP spec itself. I could see
many cases where RPC invocations would require arguments passed into the
constructor for the service...
any thoughts or comments on why this is not possible?
thanks,

Hi Peter,
Is the class com.datalex.has.travelservices.xmlservices.XMLHotelService an
interface or an abstract class?

I'm assuming you are using type="java" in your
deployment descriptor.
Think about it:
The request comes in
The JavaProvider needs an instance of your class to
dispatch on.
It wants to create one, but can't because there is no
default constructor, only one which expects a couple
of parameters about which it has no idea....
What would you like it to do ?
Sounds like you need a custom? Provider which looks up
an existing HotelService...
or perhaps I am barking up the wrong tree....
