wsdl2java java code generation for multiple hosts
Hello,
Is it possible to generate a java service using the CXF wsdl2java
(JAX-WS front end) in such a way that we can use the service with more
than one host?
Basically, I am working on a project where a centralized console
communicates via web services to a number of agents running on remote
hosts.
On the console side I want to be able to use one set of wsdl generated
stub classes and just tell the ServiceImpl class which host to connect
to.
Is this possible?
Thanks,

Yes. There are a couple of options:
1) When you create your Service object, the first parameter is the
wsdl URL to use. If you point that to the wsdl (possibly the live "?
wsdl" on the host you want), any proxies (getPort(..)/createPort(...))
stuff created from there will use the URL's in that wsdl.
2) After calling the getPort/createPort, you can override the address
in it by doing:
((BindingProvider)port).getRequestContext().put(
BindingProvider.ENDPOINT_ADDRESS_URL,
address);
With #2, memory footprint will be less and the startup is quicker as
the wsdl can be cached. Only one wsdl is used and it's just the
address that is overridden. However, you have to make sure that
proxy is synchronized or only used on one thread or something as use
of the RequestContext is not thread safe. (Although in 2.1/2.0.6,
there is a way to make it thread safe at the expense of using more
ThreadLocals internally)

Sure. You can always override the URL from the WSDL by asking the
endpoint nicely, and the server side will always patch the generated
WSDL to show the place it's actually sitting unless you override that.

Hello Chris,
I am using the JaxWsProxyFactoryBean to do what you described. In the
sample code here I went java first but this should work the same for
wsdl2java.
You simply set the url of the service in setAddress and then initialize
a stub for this service.
Is this what you wanted?
Best regards
Christian
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(HelloWorld.class);
factory.setAddress("http://localhost:9000/helloWorld");
HelloWorld client = (HelloWorld) factory.create();
String reply = client.sayHi("HI");
