OWSM Custom Step - Determine Remote Address

Question

I'm working on a custom step that provides custom metrics for some of our web services (BPEL). The only thing that I haven't been able to figure out is the remote address.
The heart of my code is:
public IResult execute(IMessageContext messageContext) throws Fault {
Result result = new Result();
result.setStatus(IResult.FAILED);
boolean isRequest = (IMessageContext.STAGE_REQUEST.equals(messageContext.getProcessingStage()) || IMessageContext.STAGE_PREREQUEST.equals(messageContext.getProcessingStage()));
if (!isRequest) {
result.setStatus(IResult.SUCCEEDED);
return result;
try {
log(messageContext);
result.setStatus(IResult.SUCCEEDED);
} catch (Exception ex) {
messageContext.getInvocationStatus().setErrorMessage(ex.getMessage());
generateFault(ex.getMessage());
return result;
private void log(IMessageContext messageContext) throws Exception {
String client = null;
try {
client = ((MessageContext) messageContext).getRemoteAddr();
// HttpServletRequest httpServletRequest = (HttpServletRequest) messageContext.getProperty("javax.servlet.request");
// if (httpServletRequest != null) {
// client = httpServletRequest.getHeader("Host");
} catch (Exception ex) {
String msg = "Unable to extract the client IP address.";
throw new Exception (msg);
<continue capturing metrics and log to the database>
The problem is, client is always null. I've tried both techniques I've found online and neither of them seem to produce any results. Could there be some server configuration that is preventing this information from be sent to OWSM?

mrmora,
After opening a Service Request and communicating with one of Oracle's reps, I was told that the HttpServletRequest (and I guess other client info) is never available for either the Server Agent or Client Agent.
I created a Gateway, instead, and and I'm now getting the HttpServletRequest and the client's IP. Both of these codes now work:
HttpServletRequest request = (HttpServletRequest)messageContext.getProperty("javax.servlet.request");
String clientIP = httpSrvltRqst.getRemoteHost();
=====
String clientIP = ((MessageContext)messageContext).getRemoteAddr();
Thanks.
