Excellent trick! Thanks for the help.
I had been toying with passing the two values I need in with
.getStub()._setProperty("weblogic.webservice.client.proxyusername",myVal
ue) and "context.getProperty("weblogic.webservice.client.proxyusername")
and the password property. Because no proxy server address was defined,
the username and password values were ignored by the control and
service, but my handler could still use them. But I think your method
of using Headers is cleaner and not as "hackish".
Also, the solution needs to be thread safe as the client will be running
in a Weblogic application of its own, which may have multiple users
logged in at once accessing the application and making parallel calls to
the web service. I still need to read up a little in this area; does
the control bean get shared among threads, or is a new instance
instantiated for each request. Is a new Handler instantiated for each
request, etc.
Thanks again for your help,
Ben

Ben,
There is a easy way to pass properties to either a client or server side
handler. The difference is how the handler accesses these properties.
To
set properties you would use the setOuputHeaders(Element[]) method on
the
web service control before invoking the method you want to call.
Ex:
String fragment = "<MyHeaders><MyHeader>STOP</MyHeader></MyHeaders>";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
Document d = factory.newDocumentBuilder().parse(new InputSource(new
StringReader(fragment)));
NodeList nl = d.getElementsByTagName("MyHeader");
helloWorldServiceControl.setOutputHeaders(new Element[] { nl.item(0) }
);
In the server side handler (not the case you describe) you can simply
retrieve the headers from the message context object.
Unfortunately the headers are not put on the message context until after
you
client side handler is invoked, so, there is a more round-about way to
access this data from the client handler.
public boolean handleRequest(MessageContext context)
{
List outboundHeaders = (List)context.getProperty(
weblogic.wsee.ws.dispatch.client.ConnectionHandler.OUTPUT_HEADERS);
if (outboundHeaders != null) {
Iterator iter = outboundHeaders.iterator();
while (iter.hasNext()) {
Element elt = (Element) iter.next();
if ("STOP".equals(elt.getTextContent())) {
throw new IllegalArgumentException("Stopping service
call
due to STOP header");
}
}
}
return true;
}
I am sure there are other ways to accomplish what you are after but this
works for me :)
I hope this helps,
