Description

Description:
The response HTTP header may contain information that is useful in a Java application. The context parameter is recommended to retrieve the HTTP header. For more details, refer to our document at the Java Component Implementations : Context Parameters.

Issue/Introduction

Environment

Product: TIBCO ActiveMatrix Service BusVersion:OS: All Supported Operating Systems--------------------Product: TIBCO ActiveMatrix Service GridVersion:OS: All Supported Operating Systems--------------------

Resolution

1). Add context Parameters in Component Reference.

2). In Promoted Reference->Bindings->Context Parameter Mapping, set Direction is "OUTPUT", Header Source is "HTTP_TRANSPORT_HEADERS" and Header Name is <the HTTP header you want to retrieve>.

3). In the Java application, use the code below to get the header "Content-Type" and "Expires".

//test code;

//This is test code for retrive http header "Content-Type" and "Expires" in response of Soap/Http

//We must initial MutableRequestContext before call another web service through reference.

MutableRequestContext mutableRequestContext = componentContext.createMutableRequestContext();

componentContext.setRequestContext(mutableRequestContext);

System.out.println("mutableRequestContext object has been created!");

//invoke external web service

TimeResponseDocument resp = getDateManagerPT().getCurrentTime(timezone);

System.out.println("--> Date Manager Component Response: \n\t\t" + resp.getTimeResponse());

CallbackContext callbackContext = mutableRequestContext.getCallbackContext();

System.out.println("callbackContext object has been created!");

String http_header1 = callbackContext.getParameter("contextParameter3", String.class);

String http_header2 = callbackContext.getParameter("contextParameter4", String.class);

System.out.println("http_header_Content_Encoding and http_header_Expires strings has been created!");

System.out.println("---------------------------------------------");

System.out.println("Content-Type = "+ http_header1);

System.out.println("Expires = "+ http_header2);
