How to identify particular handler with an actor value?

[Goran Markovic]

Hi, I didn't do much with intermediaries, mostly SOAP has one ultimate receiver. Here is the examlpe.

//Create header
QName passwordQName = new QName(NS, "passwordHeader");
SOAPHeaderElement passwordHeader =
header.addHeaderElement(passwordQName);
passwordHeader.addTextNode("s3cr3t");
passwordHeader.setActor("http://example.com/authenticator");

This code uses the setActor method on the header element, creating a SOAP envelope
that looks like this:

<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<passwordHeader xmlns="http://soacookbook.com/saaj"
SOAP-ENV:actor="http://example.com/authenticator">
s3cr3t
</passwordHeader>
</SOAP-ENV:Header>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Question is :
Since only the nodes in the message path that identify themselves with an actor value of (example)
http://example.com/authenticator will process the appropriate header passwordHeader header element, how do I IDENTIFY certain node (handler) to carry the particular actor (or role, depending of SOAP version) value?
Thanks
