I have created SOAP client in pure java. Also I have implemented SOAPHandler to trace the SOAP requests and responses. But when I see the sysouts the header part is missing in the request. Note that I am calling an enterprise service and that requires a mandatory security header for the service to be called. I am getting proper response with my security header back in the response and also is being sysout. What could be the issue for blank header trace from SOAPHandler ? Below is my handler code:
public class SOAPLoggingHandler implements SOAPHandler<SOAPMessageContext> {
private static final Logger log = LoggerFactory.getLogger(SOAPLoggingHandler.class);
public boolean handleMessage(SOAPMessageContext context) {
log.info("handleMessage");
logToSystemOut(context);
return true;
}
public boolean handleFault(SOAPMessageContext context) {
log.info("SOAP Fault Occur");
logToSystemOut(context);
return true;
}
public void close(MessageContext context) {
log.info("close");
}
public Set<QName> getHeaders() {
log.info("getHeaders");
return null;
}
protected void logToSystemOut(SOAPMessageContext smc) {
final Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
final String message = !outboundProperty.booleanValue() ? "Web Service Response\n" : "Web Service Request\n";
logMessage(smc, message);
}
protected void logToSystemOut(SOAPMessageContext smc, String message) {
logMessage(smc, message);
}
private void logMessage(SOAPMessageContext smc, String message) {
try {
final ByteArrayOutputStream oStream = new ByteArrayOutputStream();
final Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
transformer.transform(new DOMSource(smc.getMessage().getSOAPPart()), new StreamResult(oStream));
oStream.close();
log.info(message + new String(oStream.toByteArray()));
} catch (final Exception e) {
log.warn("Failed to log web service message", e);
}
//some custom logging going on below - could be ignored
SomeLogger someLoggerObj = SomeLogger.getInstance();
try {
someLoggerObj.logSomeMessage(smc, message);
} catch (SOAPException e) {
log.error("SOAP Exception occurred :", e);
} catch (TransformerException e) {
log.error("TransformerException Exception occurred :", e);
}
}
}
My Header is seen as:
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
