How to determine remote host on a RESTful Web Service

This is your Restfull service (At least one method):
@GET @Path("/{enrollmentId}/{codeword}") @Produces("application/xml") public String doGet(@PathParam("enrollmentId") final String enrollmentId, @DefaultValue("Local") @QueryParam("sysName") final String sysName, @QueryParam("msgId") final String msgId, @DefaultValue("http://127.0.0.1:8080/") @QueryParam("callbackUrl") final String callbackUrl, @PathParam("codeword") final String codeword) { MessageEntity messageEntity = null; if(CODE_WORD.equals(codeword)){ messageEntity = this.processRequestOnJbpm4(enrollmentId, sysName, new VMID().toString(), callbackUrl); }else{ log.warn("Invalid codeword while using GET method"); messageEntity = new MessageEntity(); messageEntity.setEnrollmentId(enrollmentId); messageEntity.setSysName(sysName); messageEntity.setCallbackUrl(callbackUrl); messageEntity.setErrorMessage("Invalid codeword while using GET method"); } return XMLUtil.serializeObject(messageEntity); }

As you can see, we don't have available the popular Request object, now what we can do is just to add another parameter to our method, and Listo!

@Context javax.servlet.http.HttpServletRequest request
