Hi,
I'm trying to extend the wsn-producer example by adding the WS-Resource to
a remote ServiceGroup.
For doing so, I added the wsrf-sg:Content property to the existing resource
properties, extended the MyCapabilityImpl.java class by adding the
getContent(), setContent(Element e) methods and I added the WssgConstants.
CONTENT_QNAMEto the _PROPERTIESarray.
Property in the WSDL-File:
<xsd:element ref="wsrf-sg:Content" minOccurs="0" maxOccurs="1"/>
I added the following test-content to the WsResource.rmd file (also added
the wsrf-sg namespace)
<Property name="wsrf-sg:Content" modifiability="read-write" mutability=
"mutable">
<InitialValues>
<wsrf-sg:Content>
<wsrf-sg:RPDoc>
<myns:ServerName>TestServerName</myns:ServerName>
</wsrf-sg:RPDoc>
</wsrf-sg:Content>
</InitialValues>
</Property>
Now I'm getting the following exception when initializing the resource by
using the WsnTestclient. I didn't add any ServiceGroup related code so far.
java.lang.NullPointerException
