Deserialization Problem
Hello All,
Can someone give me some advice regarding the following deserialization
error. See error message below.
My setup is as follows. Win2K with JDK1.3.1_02. I downloaded and unzipped
wsif-all-2.0alpha3.zip. I also downloaded activation.jar (v1.0.2) and
mail.jar (v1.3) and copied them into their respective locations under the
wsif-2.0alpha3/lib directory.
When I run the sample:
java complexsoap.client.dynamic.Run samples/complexsoap/Zip2Geo.wsdl 78729
I get the following error message.
-------------------------

-------------------------
Peeking at the code (Run.java) it clearly is registering the LatLongReturn
type, i.e., calls
service.mapType(new QName("http://ws.cdyne.com","LatLongReturn"),
Class.forName("complexsoap.client.stub.com.cdyne.ws.LatLongReturn") );
If this sample is supposed to work then I guess I have a
configuration/installation problem. Any one else seen this problem?
Thanks,

Re: Deserialization Problem
Posted by Rob Bugh <rb...@journee.com>.
I think I've traced down the problem I'm having with the
complexsoap.client.dynamic.Run sample. The problem I was seeing was a
deserialization error on the output part of the operation which should not
have happened because it was explicitly registered in the sample app
(Run.java). The problem is due to the encodingStyle of the call object
changing between the time the output part was registered and the call
object invoked. Specifically, in the invokeRequestResponseOperationDocument
method in
org.apache.wsif.providers.soap.apacheaxis.WSIFOperation_ApacheAxis there is
a section of code that looks like this (my comments are preceeded by "//
<=="):
Call call = wsifPort.getCall(); // <==call object created with
default encodingStyle ="http://schemas.xmlsoap.org/soap/encoding/"
// Make sure we're making a fresh start.
call.removeAllParameters();
call.clearHeaders();
//TODO need to sort out the namespace QName bindingQN =
wsifPort.getBindingName();
if (bindingQN != null) {
setInputNamespace(bindingQN.getNamespaceURI());
}
// if (inputSOAPParts == null) {
prepare(call); // <== Registers the output part with AXIS. The
TypeMapping object retrieved from AXIS to hold the mapping is keyed by the
Call object's encodingStyleName.
// }
call.setSOAPActionURI(getSoapActionURI());
call.setTargetEndpointAddress(wsifPort.getEndPoint());
call.setEncodingStyle(null); // <== Resets the encodingStyle to
null. After the call completes the deserializer for the registered part is
not found because AXIS is looking in the wrong TypeMapping.
So the question is should the encodingStyle be set to null? If so, maybe it
should be set before the call to prepare(call).
Hope this helps,
