So I added a header on the server side using the code below,
I can see the header in client side logging, but how do I
grab it on the client side? I tried an interceptor but it is
not finding any headers. What am I doing wrong?
Server side code:
Document d = DOMUtils.createDocument();
Element overflowElem = d.createElement("overflow");
overflowElem.setTextContent(String.valueOf(overflow));
QName q = new QName(SCHEMA_PREFIX + "headers_ns.xsd",
"OverflowHeader", "h");
SoapHeader overflowHeader = new SoapHeader(q, overflowElem);
...
List<Header> headers = CastUtils.cast((List<?>)
messageContext.get(Header.HEADER_LIST));
...
headers.add(overflowHeader);
Client side logging shows:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
<soap:Header><overflow>false</overflow></soap:Header>
...
Client side code:
class HeaderInterceptor extends AbstractSoapInterceptor {
public HeaderInterceptor() {
super(Phase.READ);
}
public void handleMessage(SoapMessage message) throws Fault {
List<Header> headers = message.getHeaders();
if(headers.size() == 0) {
log.info("HEADER.size = 0");
return;
}
for (int i = 0; i < headers.size(); i++) {
log.info("HEADER " + i + ": " + headers.get(i).getName());
}
}
}
Thanks,
Dan
