Hi Vito,
Message handlers can be configured in two ways:
1). Via the config.xml file (which is fed to xrpcc tool)
2). Programmatically within the client code
Client-side handlers can be configured in both the ways. However
server-side handlers can be configured only the first way.
To configure a client side handler (ClientHandler) and server side
handler (ServerHandler) via the first way, this is a schema fragment
required in config.xml file:
<handlerChains>
<chain runAt="client">
<handler className="ClientHandler">
<property name="fooClient" value="barClient"/>
</handler>
</chain>
<chain runAt="server">
<handler className="ServerHandler">
<property name="fooServer" value="barServer"/>
</handler>
</chain>
</handlerChains>
You can register handlers per interface or per service. Thus this
fragment can nested within <interface> element or within <service> element.
Here ClientHandler and ServerHandler are your handler classes
implementing javax.xml.rpc.handler.Handler interface. fooClient is a
property accessible within the handlers whose value is barClient. Ditto
for fooServer and barServer in server side handlers.
For registering handlers programmatically (second bullet above), you can
do this as following:
ClientService_Impl service = new ClientService_Impl();
HandlerRegistry handlerRegistry = service.getHandlerRegistry();
QName portQname = new QName("
http://foo.org/wsdl", "YourPort");
HandlerChain handlerChain = handlerRegistry.getHandlerChain(portQname);
HandlerInfo handlerInfo = new HandlerInfo(ClientHandler.class, null);
Hashtable hashtable = new Hashtable();
hashtable.put("fooClient", "barClient");
handlerInfo.setHandlerConfig(hashtable);
handlerChain.add(handlerInfo);
Here ClientService_Impl is your generated service class on the client side.
Note: Handler programming model is going to change in the next public
release of JAX-RPC.
Thanks for your interest in JAX-RPC.
