How can i reteive parameters if client who is hitting the URL and setting parameters using POST method ?
Using GET method the parameters get appended in the "X-Query-String".
With POST i couldn't see any "X-Query-String" getting generated. Nor the parameters were available in any field in HTTP Input Header |

Have you looked at the HTTPServletRequest being passed as parameter on the post? Have you looked at the servlet request's attributes?
Have fun

HttpServlet:
| Quote: |
doPost
protected void doPost(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException,
IOException
Called by the server (via the service method) to allow a servlet to handle a POST request. The HTTP POST method allows the client to send data of unlimited length to the Web server a single time and is useful when posting information such as credit card numbers.
When overriding this method, read the request data, write the response headers, get the response's writer or output stream object, and finally, write the response data. It's best to include content type and encoding. When using a PrintWriter object to return the response, set the content type before accessing the PrintWriter object.
The servlet container must write the headers before committing the response, because in HTTP the headers must be sent before the response body.
Where possible, set the Content-Length header (with the ServletResponse.setContentLength(int) method), to allow the servlet container to use a persistent connection to return its response to the client, improving performance. The content length is automatically set if the entire response fits inside the response buffer.
When using HTTP 1.1 chunked encoding (which means that the response has a Transfer-Encoding header), do not set the Content-Length header.
This method does not need to be either safe or idempotent. Operations requested through POST can have side effects for which the user can be held accountable, for example, updating stored data or buying items online.
If the HTTP POST request is incorrectly formatted, doPost returns an HTTP "Bad Request" message.
Parameters:
req - an HttpServletRequest object that contains the request the client has made of the servlet
resp - an HttpServletResponse object that contains the response the servlet sends to the client
Throws:
IOException - if an input or output error is detected when the servlet handles the request
ServletException - if the request for the POST could not be handled
See Also:
ServletOutputStream, ServletResponse.setContentType(java.lang.String)
|
This tells me that your parameters are somewhere in the stream. Best bet to go hunting for is the HttpServletRequest... and the context.

I am sorry i am asking again. I have just a month experience on this and i m not sure how to go about this.
What i have done till now -
1. Used HTTPInputNode. Given my URL there.
2. Tried hitting the URL. The parameters are getting set in the JSP with the servlet code as follows -
public void doPost(HttpServletRequest request, HttpServletResponse resp)
throws ServletException, IOException {
HttpSession session1 = request.getSession(false);
String userid = null;
String password = null;
int count = 0;
if (request.getParameter("userid") != null
&& request.getParameter("password") != null) {
userid = request.getParameter("userid");
password = request.getParameter("password");
user.setPassword(password);
}
3. From MB - i get
Message --> Properties
Message --> HTTPInputHeader |

Try setting the body parser to BLOB and see in the parameters turn up there...
If not, post the output of a trace node after the HTTPInput node...

Prove it with a trace, as my most worthy associate has said.

It will not be in a header if it is not actually a query string. I suspect it will be in the body as x-www-form-urlencoded data or similar...
Kind Regards,

Having a first look at the message doesnt really show that the values are there.
Will it be any encrypted format or will be be as is set in the jsp and sent using POST method ? |

Have a second look. In a trace, not the debugger.

Thanks all for all the help you guys extended.
I was successfully able to retrieve the parameters with the suggestions and ideas you guys gave 
It was all about reading the message as a BLOB and then casting it to retrieve the original parameters... |
