How did you get a stub with a return of java.util.Collection. I don't see
how WSDL2Java could produce this kind of stub.

I have a method which returns a Collection. Below is the generated client
stub which accurately shows it will return a Collection.
However, the actual object typ of resp is Object[]. This causes a
ClassCastException.
public java.util.Collection retrieveContractListForAsset() throws
java.rmi.RemoteException{
if (super.cachedEndpoint == null) {
throw new org.apache.axis.NoEndPointException();
}
com.rbs.base.client.remote.RBSCall call = getCall();
call.setReturnType(new javax.xml.rpc.namespace.QName
("http://util.java";, "Collection"));
call.setUseSOAPAction(true);
call.setSOAPActionURI("");
call.setOperationStyle("rpc");
call.setOperationName(new javax.xml.rpc.namespace.QName
("http://business.agreement.rbs.com";, "retrieveContractListForAsset"));
Object resp = call.invoke(new Object[] {});
if (resp instanceof java.rmi.RemoteException) {
throw (java.rmi.RemoteException)resp;
}
else {
return (java.util.Collection) resp;
}
}
Currently to fix the problem, I modify the return line to the following:
return (java.util.Collection)java.util.Arrays.asList((Object
[])resp);
The only side effect from this is that the client which called the method
should new a collection and pass in the return value from the stub
into the constructor which will copy the collection contents to the new
collection object.
i.e Collection col = new Vector( returnFromStubMethod);
or Collection col = new ArrayList( returnFromStubMethod);
Is there any plan to fix the stub generation or alternate suggestions?
Thanks,
David Cole
