AddHeader.VI

I have a problem with the LabviewHTTPclient.lvlib:addheader.vi. It adds a header, but it is not clear the value of the header when an empty string (as described in the help file). I use it for interfacing with a RESTful Web service that requires custom headers. Now, I have to close and reopen the "connection" to get rid of the old value of the header. Furthermore, I can't replace the header: it will be postfix of new values to the old value.

Hello

According to your information, I found a CAR (corrective action request) for your problem.

Thus, our R & D is updated on this incorrect behavior.

A possible workaround is: create and destroy a client handle for each request.

You now have enough information?

  • 33 Firefox does not display a pdf file when using the response object

    33.0.2 Firefox does not display pdf files by using the code below in an asp.net program, that works for the previous versions of Firefox and also works with IE. I'm using the built-in pdf viewer. All my plugins are disabled.

               Dim strPDF As String
           strPDF = Session("filname")   'pdf filename

  • How we prevent save as alwways .csv file adding .txt file name if I choose the action "open with?"

    My download of csv ASP page is to call:

    Response.Clear
    Response.AddHeader "content-disposition", "attachment; filename = filename.csv ".
    Response.ContentType = "Content-Type: text/csv; "charset = utf - 8"

    When I click on the link to this ASP page, appears the dialog 'Opening filename.csv' Firefox:

    filename.csv
    which is a: Text Document

    If I choose 'Open with < any Application name >' the file is always opened by the application with a .txt appended to the name of the file, which, in this case, my spreadsheet software prevents opening correctly.

    (a) how can I prevent the .txt is added the filename if the OpenWith is used?

    (b) is there a way to add a CSV type to the tools-> Options Applications Content Type list to avoid the message "which is a: Text Document"?

    This behavior does not occur in Chrome, Opera, Safari or IE.

    It was a failure of the server, not Firefox.

    ASP should have been:

    Response.ContentType = text/csv"; "charset = utf - 8"

    Fixed!

    Thank you

  • Adding network request headers

    How can I add network request header?

            bool result = connect(reply, SIGNAL(finished()), this,
                    SLOT(onLoginAuthenticationLoaded()));

    "BOLD" part is wrong, needing a fix for it.

    in android, I'm doing this

  • The phone queue stats

    I have a client who would like the agents must be able to view the stats on their phone line, as well as the Office of the agent. Could someone point me in the right direction?

    Hello

    Therefore, here.

    The setup of the example is as follows. First of all, a few basic terms I use in the script.

    -cc - aw: it the name of the server running the script. Is the Server Admin CIM Workstation (AW) (the script pulls information from the local database (127.0.0.1) using SQL auth (it is very important: you must have mixed auth mode enabled in SQL server, if you installed AW according to Cisco docs, you should already have it activated))

    -vialia: the name of the instance of the installation of the ICM. This means, on the AW server we can see two databases CIM: vialia_awdb (information AW), vialia_hds (based on historical data). We only need first here.

    -statreader: the account name we are connecting to SQL server. This should, of course, have the necessary rights enabled for the vialia_awdb database (public and db_owner should be OK, but you can play with restrictions)

    - [email protected] / * /: the password for the above account

    -url =http://cc-aw/stats/sg_boston.asp: this is the URL of the script. Otherwise, the name of the script itself is sg_boston.asp (display of the information on the skills of Boston Group) and is saved in the C:\Inetpub\wwwroot\stats\ folder. You may need to give him the run script permission.

    -5099: is the SkillTargetID of the Group of skills that we want to see the information. It is, for example, the SkillTargetID of the skills of Boston group. You can find the SkillTargetID of all groups of skills in the vialia_awdb.dbo.Skill_Group table (try SELECT * FROM vialia_awdb.dbo.Skill_Group in Query Analyzer for the complete list)

    Very large lines in the script:

    Response.AddHeader "Refresh", "10; URL =http://cc-aw/stats/sg_boston.asp"

    This adds a header, instructing the phone to recharge the (same) script every 10 seconds.

    oConn.Open "driver = {SQL Server}; Server = 127.0.0.1; UID = statreader; pwd =[email protected] / * /; database = vialia_awdb ".

    For uid, pwd, and database values: see the explanation above.

    So please change all these values!

    It is always good to try the script in your favorite web browser. If you get an XML object with some realistic figures, so everything is OK, you can set the URL in the form of inactive URL on phones of officers.

    If you get an error message, then:

    -check if the script itself is accessible by IIS,

    -Execute permission enabled?

    -OK SQL Login?

    Have fun. And please let me know.

    P. S.

  • ADF entry Force of user and password?

    Hello!

    We use JDev 11.1.16 and I have an ADF app that works most of the time. There is a problem when users open the application in the browser and the form request not a user name / login and then when the data technology shows in the form of empty tables to users.  If we close the browser and then try again and we get a prompt for a user to connect then everything works fine. I guess the browser puts cached login information so that if we hit the page again the user does not log in... but when she does then the tables show them all empty. I was wondering fi anyone ideas on what we could try on this!  I have set to http basic security.

    -are there a way to not do things in the browser's cache?

    -is it possible to have the app always required that the connection happen?

    d ' other options ?

    Thanks in advance for any input.

    Hello

    Like normal J2EE application, must be added

    response.setHeader ("Pragma", "non-cache" "");

    response.setHeader ("Cache-Control", "non-cache, non-magasin, max - age = 0, must-revalidate");

    response.setDateHeader ("Expires", 0);

    Concerning

    Change: response.addHeader ("Content-Disposition", "attachment; filename = "reportName +".pdf");"

    To: response.addHeader ("Content-Disposition", "inline; filename = "reportName +".pdf");"

    Browser first tries to show the PDF, and if no pdf reader is available, you will get the download dialog box.

    (and remove JasperViewer.viewReport (jasperPrint, false);  )

  • Add image beside the import XML content

    Dear users of InDesign,

    Importing text in an InDesign template (essentially in a story).

    When I import this XML file do some tweaking with XML-rules, like adding a title.

    function AddHeading() {}

    myIdName = "AddHeading";

    This.XPath = "//phoneno [1];

    This.Apply = function (myElement, myRuleProcessor) {}

    {with (MyElement)}

    var myPhoneNo = myElement.xmlContent;

    myElement.xmlContent.insertionPoints [0] .silence = String ("phone numbers \r'");

    myPhoneNomentioning [0] .appliedParagraphStyle = app.activeDocument.paragraphStyles.item ("HeadingPhoneNo");

    }

    Returns true;

    }

    }

    What I need to do is add an Image (a phone icon) next to the additional title ("phone numbers ').

    Because everything is floating in a story, I can't have the geometric limits for this paragraph.

    Any ideas how to achieve a placement of an image in this context?

    Thank you!

    Thanks to Peter, here is the approach solve my problem:

    (adopted from pkahrel great help in this thread: Re: image of place as anchor object by finding the text...)

    function AddHeading() {}

    myIdName = "AddHeading";

    This.XPath = "//phoneno [1];

    This.Apply = function (myElement, myRuleProcessor) {}

    {with (MyElement)}

    var myPhoneNo = myElement.xmlContent;

    myElement.xmlContent.insertionPoints [0] .silence = String ("phone numbers \r'");

    myPhoneNo.words [0] .appliedParagraphStyle = app.activeDocument.paragraphStyles.item("HeadingPhoneNo");

    var anchor = myElement.storyOffset.textFrames.add ();

    var f = new File('/Users/PATHTOIMAGE/image.png');

    var f = [0,0, "10mm", "10mm"];

    var myObjectStyle = app.activeDocument.objectStyles.item ("HeadingPhoneNo");

    anchor.appliedObjectStyle = myObjectStyle;

    Anchor.contents = myElement.contents;

    anchor.geometricBounds = GB;

    Anchor.place (f);

    Anchor.fit (FitOptions.CONTENT_TO_FRAME);

    }

    Returns true;

    }

    }

    I use three files in lib jasper

    iText - 2.1.7

    JasperReports - 4.0.1

    JasperReports-fonts - 4.0.1

    This code displays the report in adobe reader only and in the browser like firefox after some adjustments in the browser.

    Concerning

  • Control browser caching

    Hello

    I have the problem that when the redeployment of an application where the images or js changed these changes appear not due to browser caching.

    I'm looking for is a way to disable is cached in the browser or be able to clear items cached.

    I tried the following:

    1. replace the phaselistener with the following and added to the faces lifecycle:

    public void beforePhase (PhaseEvent event)
    {
    FacesContext facesContext = event.getFacesContext ();
    HttpServletResponse response = (HttpServletResponse) facesContext
    .getExternalContext (m:System.NET.FtpWebRequest.GetResponse ());
    response.addHeader ("Pragma", "non-cache" "");
    response.addHeader ("Cache-Control", "non-cache");
    Stronger according to blog comment below which references the HTTP specifications
    response.addHeader ("Cache-Control", "non-magasin");
    response.addHeader ("Cache-Control", "must-revalidate");
    a date in the past
    response.addHeader ("Cache-Control" "max - age = 1");
    }

    These options of cathing seems not to apply to images and js.

    2 adding filters by adding to the web.xml file

    < filter >

    < name of filter > ACF < / filter-name >

    > class filter < oracle.adf.view.rich.webapp.AdfFacesCachingFilter < / class filter >

    < / filter >

    < filter mapping >

    < name of filter > ACF < / filter-name >

    < url-pattern > * < / url-pattern >

    < / filter-mapping >

    That doesn't seem to change the Cache-Control:public to Cache-Control:public, max - age = 99999, for me, it is probably somewhat good approach.

    Then, I added the cache rules to the adf-config. XML but they do not seem to override the defaults and I still get just the cache-control: public, max - age = 99999. The images are stille caches and does not change without clearing the cache of the browser!

    Here's my adf - config.xml:

    <? XML version = "1.0" encoding = "UTF-8"? >

    I also tried to move the rules outside of < / adf-adfm-config > but with the same result.

    I use Jdev. 12.1.2.0.0.

    Its really important that the js and images are refreshed after a redeployment users shouldn't clear it cached so that the application can run.

    TIA

    Here's a similar approach, but with servlet filter, then you can try:

    http://StackOverflow.com/questions/8259286/disabling-browser-cache-JSF

  • We need a separate servlet class to open a report of jasper for each button in report or not?

    Mr President.

    We need a separate servlet class to open a report of jasper for each button in report or not?

    My code for the servlet is as under which works very well for a single report.

                   {

    For any help, I'll be very grateful

    Concerning

    Tender,

    As I mentioned in the other thread, the var0 comes null which causes this problem.

    Why var0 just null?

    You must change the property of destination as below:

    You must add "="

    See you soon

  • Can a report of Jasper operate with an af:button on a page fragment (jsff) or simply on a jsf page?

    Mr President.

    Can a report of Jasper operate with an af:button on a page fragment (jsff) or simply on a jsf page?

    Because I'm running report jasper jsff page but it does not work but the same report runs on a jsf page.

    Concerning

    Cherish!

    The answer to this question is Yes

    We can run report jasper with a button on a page jsff using the servlet class

  • Client application to consume the web service with security

    I need to write a simple client to access a WS.

    I can't do things

    1. Change the server
    2. Add external jars

    The customer will be part of a command line call and will work as a stand alone.

    I searched all day and have found hundreds of examples of wave, too complex, based mainly on SOAPHandler (who tells me that I need to install the server components that I can't do)

    I grasp the General requirements but finds it difficult to know how to add security features to the header.

    What should I do to add the chips of user name and password in the header?

    It is where I am so far.

  • Jdev 12.1.3: Button that generates the pdf Jasper report does not return a user control

    Hi experts,

    I have a page jspx with a button that generates a PDF report of Jasper.

    My problem is that after pressing on and download the pdf file, the user cannot access other links more.

    If I put the mouse over the button is watch the mouse pointer as he was waiting for something.

    Therefore, the user must close the browser (I checked with Chrome, Firefox and IE) or refresh the page.

    This is the key:

    <af:button text="Print Project" id="ctb4"
                                                   actionListener="#{backingBeanScope.JasperBean.runReportPVT}"
                                                   partialSubmit="false"
                                                   icon="/images/icons/print_ena.png"/>

    And this is the code of the bean to support:

    public void executeReport() throws Exception {
  Connection conn = null;
  Date date = new java.util.Date();
  String timestamp = new Timestamp(date.getTime()).toString();
  try {
      HttpServletResponse response = getResponse();
      ServletOutputStream out = response.getOutputStream();
      response.setHeader("Cache-Control", "max-age=0");


      response.addHeader("Content-disposition", "attachment;filename=report_" + timestamp + ".pdf");
      
      response.setContentType("application/pdf");
      ServletContext context = getContext();
      InputStream fs =
          context.getResourceAsStream("/reports/template1.jasper"); 
      JasperReport template = (JasperReport) JRLoader.loadObject(fs);
      template.setWhenNoDataType(WhenNoDataTypeEnum.ALL_SECTIONS_NO_DETAIL);
      conn = getConnection();
      JasperPrint print = JasperFillManager.fillReport(template, paramMap, conn);


      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      JasperExportManager.exportReportToPdfStream(print, baos);
      
      out.write(baos.toByteArray());
      out.flush();
      out.close();
      FacesContext.getCurrentInstance().responseComplete();


  } catch (Exception jex) {
      jex.printStackTrace();
  } finally {
      close(conn);
  }
}

    If you do not need to view the report online, you can use af:fileDownloadActionListener
