----------------------------
Summary: Creating a proxy from another proxy does not produce the
same parameters as expected
Key: CXF-7360
URL: https://issues.apache.org/jira/browse/CXF-7360
Project: CXF
Issue Type: Bug
Affects Versions: 3.1.10
Reporter: Asi Lev
Priority: Minor
I'm working on an ONVIF web service client program that manages ONVIF devices.
I've used wsdl2java as follows:
wsdl2java -d C:\onvif\onvifMedia -client -exsh false -dns true -dex true
-verbose media.wsdl
I've used the same command for device.wsdl and events.wsdl
The files were downloaded from https://www.onvif.org/profiles/specifications/
In my project, I've used the following code in order to pull events from an
ONVIF device:
CreatePullPointSubscriptionResponse pullPointSubscriptionResponse =
event.createPullPointSubscription(parameters);
PullPointSubscription pullPointSubscription =
pullPointSubscriptionResponse.getSubscriptionReference().getPort(PullPointSubscription.class);
PullMessages pullMessagesParameters = new PullMessages();
pullMessagesParameters.setMessageLimit(1);
javax.xml.datatype.Duration duration =
DatatypeFactory.createDuration("PT1M");
pullMessagesParameters.setTimeout(duration);
try {
PullMessagesResponse pullMessageResponse =
pullPointSubscription.pullMessages(pullMessagesParameters);
} catch (PullMessagesFaultResponse_Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int d=1;
} catch (TopicNotSupportedFault | TopicExpressionDialectUnknownFault |
InvalidTopicExpressionFault
| InvalidMessageContentExpressionFault |
InvalidProducerPropertiesExpressionFault
| UnacceptableInitialTerminationTimeFault |
NotifyMessageNotSupportedFault | ResourceUnknownFault
| UnsupportedPolicyRequestFault | InvalidFilterFault |
SubscribeCreationFailedFault
| UnrecognizedPolicyRequestFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
According to ONVIF specification, the first proxy
"event.createPullPointSubscription" should send a "CreatePullPointSubscription"
message to the device, and the device should send back
CreatePullPointSubscription response.
Inside the response there are parameters that should be sent to the device in
order to pull the events, as "reference parameters" in the WS header.
The response is returned successfully for this code, and the parameters are
given in the returned object. I can verify this with the debugger, but they are
declared as private so I can't access them using code.
As I understand, there is supposed to be a way to create the pullMessages
service message, with the encapsulated parameters, using the response.
My attempt to do that is also in the above code. On the second line I attempt
to create the object from the response. After I initialize some parameters for
the pullMessages object, I issue the command to send the pullMessages service
message.
There are two problems I encounter in this step:
1. While the original object was created from factory as a SOAP1.2 service
client, the new object is a SOAP1.1 client, and I can't figure out how to
change that to 1.2. I would expect that an object that was generated from
another object would have the same SOAP version.
2. When the new object sends its message, there are no reference parameters in
its header as I expected. The parameters were suppose to be transformed from
the originating object.
A work around could have been to create the second object manually and add the
parameters manually, but the parameters are not visible by code, as they are
encapsulated and declared as private.
Another workaround (which I used and worked fine) is using the .toString()
method on the first object, and parsing this string which just happens to
contain the values of the private members which I needed...
