wsn consumer
hi all,
I have two questions:
1- i didn't find a wsdl description for the consumer resource in
wsn-consumer example (however there is the capability class). So i want to
ask:
can i create simple resource code without creating wsdl description for that
resource (only including standard wsdl and xsd files) and off course without
passing via wsdl2java (by coding manually) ?
1.1- If it's so, how MetadatExchangeClient.getWSDL() method can work?
2- I readed discussion between Dan and Bigtex (last february) about
wsn-consumer and how a simple java program can receive published
notification. If i understood, that's no way to receive notification
directly from wsn-producer (so we must create one resource consumer) ?
thanks for all.

Hi,
I assume you are not able to find any description for capability (
http://ws.apache.org/muse/test/wsn/consumer) in consumer wsdl file, that's
because this capability did not have any properties and operations.
Sometimes there might be a requirement that your capability is supposed to
do some initialization work and in that case you don't need any properties
and operations in that capability. Now if that is the case then there is
no way to define Empty Capability in wsdl file, that's the reason this
Empty Capability is define in muse.xml.
If you define any Empty Capability in muse.xml and invoke wsdl2java then
this will create a Java class for that Empty capability with having a
method
public void initializeCompleted() throws SoapFault
So you can provide your custom initialization code here.
I hope this will clarify the point 1.
For point 1.1 MetadatExchangeClient.getWSDL() method internally invoke
"GetMetadata" operation on "MetadataExchange" capability by passing the
dialect as "http://schemas.xmlsoap.org/wsdl/". There is already an
operation define as "GetMetadata" for "MetadataExchange" capability wsdl
file.
thanks

No the wsn-consumer can be in a separate container but must also be an
endpoint. For that matter it may or may not use Muse.

it's true that : to receive notification from wsn-producer, a wsn-consumer
must be deployed in the same container of wsn-producer ?

Ok, I looked into it by building wsn-consumer and droping it into tomcat.
Then made a small Java app that creates a MetadataExchangeClient on the epr
and tries to retrieve the WSDL. As expected this throws an error
[ID = 'ActionNotSupported'] The resource at 'consumer' does not expose an
operation with the WS-Action
'http://schemas.xmlsoap.org/ws/2004/09/mex/GetMetadata'
This is because the port does not define the method, so you can add the
following lines to the wsn-consumer.wsdl file (in the appropriate parts) and
you will be able to get the Metadata
xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" - in the schema
definition
<xsd:import
namespace="http://schemas.xmlsoap.org/ws/2004/09/mex"
schemaLocation="WS-MetadataExchange-2004_09.xsd"/>
Above in the Types Definitions
<wsdl:message name="GetMetadataMsg">
<wsdl:part name="GetMetadataMsg" element="wsx:GetMetadata" />
</wsdl:message>
<wsdl:message name="GetMetadataResponseMsg">
<wsdl:part name="GetMetadataResponseMsg" element="wsx:Metadata" />
</wsdl:message>
Above in the message section
<wsdl:operation name="GetMetadata">
<wsdl:input
wsa:Action="http://schemas.xmlsoap.org/ws/2004/09/mex/GetMetadata"
name="GetMetadataMsg" message="wsntw:GetMetadataMsg"/>
<wsdl:output
wsa:Action="http://schemas.xmlsoap.org/ws/2004/09/mex/GetMetadataResponse"
name="GetMetadataResponseMsg"
message="wsntw:GetMetadataResponseMsg"/>
</wsdl:operation>
The operation should go in the <wsdl:portType name="NotificationConsumer">
tag.

Yes, you can. What wsdl2java does (or at least part of what it does) is that
it modifies your wsdl and copies parts of the other wsdls to your main wsdl
that it deploys. For a simple consumer that only receives some notifications
the WS-BaseNotification-1_3.wsdl is the wsdl that is being used as the
"main" wsdl for the application. If you look at muse.xml in the wsn-consumer
example you will see that it maps the resource to this wsdl

For question 1.1 I am not 100% sure, and I'll need to look into it. Muse.xml
defines a capability for MetadataExchange for the client, but I was sure
that anything in Muse.xml must also be expressed in the wsdl file. So just
looking at it, I'd say the wsn-consumer should not be able to send Metadata
