  • How to use POST method in PI 7.11 when using HTTP adapter

    Hi
    I need to use the POST method when using the http receiver adapter in PI 7.11. Now the GET method is used. I am using the Addressing Type = "HTTP Destination" where you create an RFC of type 3 in SM59 and reference this in your HTTP receiver adapter.
    What do I do?

    Hi Patrick
    I need to use the POST method, not the GET method. The external partner, which is receiving our message, says, that we are using GET.
    This is from their log where we are DongEnergy:
    From DongEnergy:
    2010-01-14 09:46:11 W3SVC1 10.1.2.37 GET /DongEnergy/xxxxxxxxx.dll - 443 - 193.162.91.1 SAPNetWeaverApplicationServer(1.0;711) 500 0 0 214 172
    From Danisco:
    2010-01-14 07:54:13 W3SVC1 10.1.2.37 POST /Danisco/xxxxxxxxxx.dll - 443 - 193.XXX.191.1 SAPWebApplicationServer(1.0;640) 202 0 0 380 5984
    Could it be our firewall which vonverts the method from POST to GET?

  • Open URL, use POST method in new window

    From a Java program, how do we open a https connection, basically a secured site, in a new window and pass some parameters to the link, using POST method?

    Hi
    Is JavaProgram a Applet or Servlet?
    Opening a new window directly from server,probably not possible? From your question
    what I understand is, A html page is displayed
    and when u click on a link opens a new window.
    The parameters to the link should be posted using POST method, again
    it is not possible this can be done only by appending
    "?name1=value1&name2=value2..."to the link

  • HTTP Transformation using POST Method

    Hi, I will have to use POST method with header as application/json to get the results in http transformation. I downloaded the RESTFUL client utility from Chrome, to see how JSON would look like by passing parameters and the result is displayed as expected.  But I'm not sure how the URL to be constructed in HTTP transformation and appreciate if you have any suggestions. My URLL http://dev1.com/contract-api/contract/public/contractValidationMy input parameters:  {"hierarchies":[10],"properties":[18],"licId":123} If I use the above URL and parameters in RESTFUL client, I'm getting the output, but having difficulty in setting up the URL using HTTP transformation.  RegardsSelva

    Thanks Marc.
    Let me rephrase the scenario.
    I have an external application which is capable of sending information only in XML through HTTP requests. It does not send SOAP messages. I guess in this case, we would need to use the HTTP binding using POST method. Much like the sample at http://blogs.oracle.com/reynolds/2005/09/invoking_bpel_from_an_html_for.html which uses the GET method.
    In this sample reynolds is using the GET method. I have been trying to get the POST method to work.

  • How to use SAX parser in J2ME

    Please help me how to use SAX parser in J2ME.
    Is there any function to find the value of a particular element from a XML file?
    I am able to get Element name, Values, Attributes. But control is not in my hand, DefaultHanldler automatically invokes Character method, then only I am able to get values. But I don't know when this method gets invoked.
    Is there any way or method so that I can get value of any element or attribute just by passing element name as parameter in SAX parser?
    Is there any other parser through which I can perform this task in J2ME?
    Thanks in advance.

    Hi..
    have a look at this.

  • Sending XML messages from server to client using POST method

    Dear everyone,
    I have a simple client server system - using Socket
    class on the server side and URLConnection class on
    the client side. The client sends requests to the
    server in the form of an XML message using POST method.
    The server processes the request and responds with
    another XML message through the same connection.
    That's the basic idea.
    I have a few questions about headers and formats
    especially with respect to POST.
    1. In what format should the response messages from the
    server be, for the client? Does the server need to
    send the HTTP headers - for the POST type requests?
    Is this correct?:
       out.println("HTTP/1.1 200 My Server\r");
       out.println("Content-type: text/xml\r");
       out.println("Content-length: 1024\r");
       out.println("\r");
       out.println("My XML response goes here...");2. How do I read these headers and the actual message
    in the client side? I figured my actual message was
    immediately after the blank line. So I wrote
    something like this:
       String inMsg;
       // loop until the blank line is through.
       while (!"".equals(inMsg = reader.readLine()))
          System.out.println(inMsg);
       // get the actual message and process it.
       inMsg = reader.readLine();
       processMessage(inMsg);But the above did not work for me. Because I seem to
    be receiving a blank line after each header! (I suppose
    that was because of the "\r".) So what should I do?
    3. What are the different headers I must pass from
    server to the client to safeguard against every
    possible problem?
    4. What are the different exceptions I must be prepared
    for this situation? How could I cope with them? For
    example, time outs, IOExceptions, etc.
    Thanks a lot! I appreciate all your help!

    hello,
    1) if you want to develop a distributed application with XML messages, you can look in SOAP.
    it's a solution to communicate objects distributed java (or COM or other) and it constructs XML flux to communicate between them.
    2) if it can help you, I have developed a chat in TCP/IP and, to my mind, when you send datas it's only text, so the format isn't important, the important is your traitement behind.
    examples :
    a client method to send a message to the server :
    public void send(String message)
    fluxOut.println(message);
    fluxOut.flush();
    whith
    connexionCourante = new Socket(lAdresServeur, noPort);
    fluxOut= new PrintWriter( new OutputStreamWriter(connexionCourante.getOutputStream()) );
    a server method in a thread to receive and print the message :
    while(true)
    if (laThread == null)
    break;
    texte = fluxIn.readLine();
    System.out.println(texte);
    that's all ! :)
    If you want to use it for your XML communication, it could be a good idea to use a special message, for example "@end", to finish the server
    ex :
    while(true)
    if (laThread == null)
    break;
    texte = fluxIn.readLine();
    // to stop
    if (texte.equals("@end"))
    {break;}
    processMessage(texte );
    hope it will help you

  • How to use protected method in jsp code

    Could anyone tell me how to use protected method in jsp code ...
    I declare a Calendar class , and I want to use the isTimeSet method ,
    But if I write the code as follows ..
    ========================================================
    <%
    Calendar create_date = Calendar.getInstance();
    if (create_date.isTimeSet) System.out.println("true");
    %>
    ============================================================
    when I run this jsp , it appears the error wirtten "isTimeSet has protected access in java.util.Calendar"

    The only way to access a protected variable is to subclass.
    MyCalendar extends Calendar
    but I doubt you need to do this. If you only want to tell if a Calendar object has a time associated with it, try using
    cal.isSet( Calendar.HOUR );

  • How to use the method for field-exit to trigger the workflow?

    Dear all,
         I want the workflow to trigger , when ever the check box for DELIVERY COMPLETED is checked in ME22N .
         I have developed a method in SE18 for the corresponding field and defined function module SWE_EVENT_CREATE with BOR bus2012 and event CHANGED.
        Now how to use this method to make my workflow to trigger?Shall I create an event in delegated bus2012 and can I call this method?
    Thanks and regards,
    S.Suresh

    Hi
    You want to place your method which is defined for particular filed.right?
    For that you can go for BADI. First you check whether any badi is getting called form that tcode ME22N. Then to place your method, implement that BADI.  So whenever that BADI is getting called, it will call your event. Through Event workflow will be getting triggered.

  • How to use secondary method in workflow?

    Hi friends,
    can anyone plz let me know how to use secondary methods in workflow? it would be helpful if u explain with an example..
    thanks and regards,
    Arun.S

    Hi Arun Kumar,
    The Sec Method can be used in the user decision step. The secondary methods are executed along with the user decision step. You have 3 options. Either execute a secondary method before executing the user decision step or after execution of user decision step or while executing the user decision.
    For this define the methods either in Methods before execution of workitem execution to execute it before user decision step or Methods after execution of workitem so as to execute it after the execution of user decision.
    In order to execute a method along with user decision step execution use secondary methods (amodal call.)
    Let me know if you have any queries.
    Regards,
    Raj

  • How to use this method in JSTL?help me please!

    I know I can use "<C:set >" like as
    <c:set var="clabel3" value="${portalCustomizeBean.portalPage}"/> ,
    but now I want to use one method of portalCustomizeBean object not a attribute of it !!!!!
    who would tell me how to use?
    this is wrong in my code:
    <c:set var="clabel" value="${portalCustomizeBean.currentPageLabel}"/>
    <c:set var="clabel3" value="${portalCustomizeBean.toEntitiesExceptSpaceEscape(clabel)}"/>
    but how to use "toEntitiesExceptSpaceEscape" method in JSTL?????

    Why can't you just assign the method's return value to a variable and then print that? A bit of scriptlet code will do the trick. (As much as we all hate to use scriptlet code.)
    I believe you'll be able to do what you want in the 1.1 standard JSTL, but for now this will suffice. - MOD

  • How to use getContent() method in custom JSP Provider to display a HTML Pag

    Hi,
    If anybody knows how to use getContent() method to use in custom jsp providers (developed by ourselves) so that it can be used to retrieve a jsp page (a simple html page) ..
    I want the code in the provider java file to for the getContent method...
    Pls. get back to me asap....if any body has implemented a custom jsp provider...as it's urgent...
    I have alreday placed the JSP file in the directory structure /etc/opt/SUNWps/desktop/default/channel_dir..But still the jsp is not being displayed..
    Pls get me the getContent() method code to retrive the JSP file..
    satyabrata

    Hi,
    You don't have to do anything in the custom JSPProvider's getContent method except the call {  return super.getContent(request,response); } . If all you want is just to show your jsp, then create a channel from the default JSPProvider, and edit the property contentPage of that channel from samplecontent.jsp to your jsp name, save the changes and login again. You should see your JSP.
