Hello,
I’m running into an issue using CXF with a legacy Corba application and am
looking for some advice.
Currently I have a CXF 2.2.9 client up and communicating with a pure corba
server using java 1.6 with sun’s orbd and idlj. In this setup, the wsdl
<corba:address> location is specified using a corbaname address and in the
client I’m instantiating the corba service and port objects directly. This
is based directly upon the corba/hello_world example in the CXF samples
directory. So far so good.
The change I’m trying to make is to remove the corba address from the wsdl
because I don’t want host and port values hard-coded there. My intended
approach is to use a ClientProxyFactoryBean in the client (rather than
instantiating the corba service object directly) and specify the corbaname
address at runtime.
So based upon the original hello_world example, my updated service looks
like:
<wsdl:service name="HelloWorldCORBAService">
<wsdl:port name="HelloWorldCORBAPort"
binding="tns:HelloWorldCORBABinding">
<corba:address location="IOR:" />
</wsdl:port>
</wsdl:service>
And my updated client looks like:
ClientProxyFactoryBean factory = new ClientProxyFactoryBean();
factory.getInInterceptors().add(new LoggingInInterceptor());
factory.getOutInterceptors().add(new LoggingOutInterceptor());
factory.setServiceClass(HelloWorld.class);
factory.setAddress("corbaname::localhost:1050#HelloWorld");
HelloWorld client = (HelloWorld) factory.create();
String result = client.greetMe("Hello There");
Running this, I end up with a NullPointerException:
Exception in thread "main" java.lang.NullPointerException

I’m seeing that DescriptionInfo never gets included as part of the
ServiceInfo when buildServiceFromClass() is called on
ReflectionServiceFactoryBean; whereas DescriptionInfo does eventually get
set if instead buildServiceFromWSDL(…) is called. It’s the null
DescriptionInfo that eventually trips things up.
So in summary: Can someone help me get this running? Or is there a better
way to go about pulling host and port values out of my wsdl? Or is there
some documentation out there that I’m missing?
Thanks,
Andrew
